3�- BASIC CONCEPTS

The energy storage systems in a micro-grid can be charged with the use of renewable energies during the periods of maximum insolation. Stored energy can then be consumed during the rest of the day.

Figure 2: Purpose of the Dispenser Universal

The main purpose of the Dispenser Universal system is to control the energy demand and power of the different users of a micro-grid, with the aim of satisfying the energy needs of each user.

A good way to describe the operation of the Dispenser is with a water tank analogy, Figure 3.

Instruction Manual

Figure 3: Water tank analogy�

Dispenser Universal System

Energy can be stored in the Dispenser so that it is readily available. The capacity of the Dispenser would be equivalent to that of the water tank, i.e., the larger the tank, the higher the volume of water available.

The tank is lled according to the contracted ow rate. In the case of the Dispenser, the tank is lled constantly at a rate proportional to the contracted energy. If this ow rate is insufcient, the contract can be modied and adapted to current needs.

The consumption of water is equivalent to the consumption of energy, i.e., the higher the consumption rate, the quicker the tank will be emptied. In particular, there are three different scenarios:

 Balanced consumption, the lling and emptying rate of the tank is very similar, so there is always an acceptable level of water that can meet the needs of users at all times.

Low consumption; in this scenario the lling rate is higher than the emptying rate, so the tank is usually lled up to the top. This is not the optimum scenario, since the purpose of the management system is not to store the maximum amount of water (energy), but to nd the balance between load and consumption.

 Excessive consumption; in this scenario, the lling rate is much slower than the emptying rate, so the tank is fully drained leaving no available water (energy), which leads to a critical situation.

Figure 4: Management of the water tank lling/emptying procedures.

Instruction Manual

Dispenser Universal System

3.1.- OPERATING MODES

The Dispenser has three operating modes, depending on the load of the energy storage systems:

 Normal mode,  Bonus mode,  Restriction mode,

3�1�1�- NORMAL MODE

This operating mode corresponds to a situation in which there is a balance between the energy available in the storage systems of the micro-grid and the consumed energy.

Following the water analogy, the normal mode represents the balance between lling and emptying of the water tank.

This is the most benecial situation for a micro-grid and for the user. Therefore, the objective is to work under these conditions at all times.

3�1�2�- BONUS MODE

In this case, the storage systems have managed to store the maximum amount of energy after various insolation periods. In turn, the consumption of energy by users is not excessive. This is when a bonus is applied to the consumption of energy, reducing its price.

3�1�3�- RESTRICTION MODE

In this case, either the storage system has not fully charged after a period of time or there has been excessive consumption by users. Therefore, the consumption of energy must be limited by means of increasing its price.

3�1�4�- EXAMPLE

The irradiation curve in Figure 5 shows an insolation period between 06:00h and 18:00h, reaching the maximum level of insolation at 12:00h.

Instruction Manual

Figure 5: Example of an irradiation curve�

Dispenser Universal System

Different bonus or restriction periods can be dened according to the following criterion:

 The energy levels of the energy storage systems are low rst thing in the morning, since the users of the micro-grid have consumed energy during the night period. Therefore, a period of time between 05:00h and 08:00h must be dened, in which penalties will be applied to consumption. In this case, the unit will be operating in the restriction mode.

 The next period, between 08:00h and 16:00h, is the period of maximum insolation, during which the photovoltaic energy is enough to charge the storage systems and supply energy to users, so consumption should be encouraged during this period. In this case, the unit operates in the bonus mode.

 The maximum number of users will connect loads to the grid between 16:00 and 19:00. Even though the previous period was not of maximum insolation, if a message is not shown to the users during this period, warning them about the fact that the cost of energy can be higher than usual, simultaneous loads might be connected to the micro-grid, which will quickly consume the energy stored in the storage systems. During this period, the unit operates in restriction mode.

 Finally, a period is established for the rst and last 5 hours of the day, during which it is assumed that the consumption from the grid is not critical. Therefore, a period during which the unit works in normal mode can be dened.

Figure 6: Example of Operating modes�

3.2.- ENERGY FACTORS

The Dispenser can manage the price of energy according to the operating mode of a micro-grid through the Energy factor parameters:

 Bonus factor; when the micro-grid is in the bonus mode (excess energy is available), the price of energy can be reduced and users can consume it at a lower price.

 Restriction factor, if, on the other hand, the micro-grid is in the restriction mode (not much energy is available), the price of energy can rise and users will pay more for the energy they consume.

Instruction Manual

Dispenser Universal System

In normal mode, the price of energy remains unmodied and users pay for energy at the price stipulated.

Table 2 shows the values that these factors can adopt.

Table 2: Range of values of the energy price factor

Energy factors Range of values

Bonus factor 0.4...1

Restriction factor 1.2...3

3.3.- CONTROLLING THE MAXIMUM POWER

One of the functions of the Dispenser is to control the limits of the power that can be consumed by the user. The unit limits the maximum power available according to the type of contract and status of the micro-grid. If this power level is exceeded, the general relay is opened, disconnecting the power supply from the subscriber. ( 5.2.4.1.- GENERAL RELAY)

This function allows each user of the installation to dene the maximum power available, establishing the number of loads that can be connected to the grid. Therefore, this limiter can be used to ensure that the power for which the electrical network has been designed is never exceeded.

The Contracted power is dened in the DISPENSER-SOFT application as:

Contracted power = Base power x Power multiplier�

Where: Base power : base power of the micro-grid.

Power multiplier : multiplier factor that depends on the type of contract.

The maximum power value is modied according to the status of the micro-grid.

3�3�1�- NORMAL MODE

In this operating mode, the maximum power that can be consumed by the user is equal to the contracted power.

Instruction Manual

Figure 7: Controlling the maximum power, Normal mode�

Dispenser Universal System

3�3�2�- BONUS MODE

When the micro-grid is operating during an excess power period, the Dispenser allows the user to consume more power than that established by the user's contracted energy.

To do so, the Excess factor parameter has been dened in the DISPENSER-SOFT application as a multiplier factor that increases the value of the maximum power available for consumption.

Figure 8: Controlling the maximum power, Bonus mode�

Table 3: Range of values of the excess factor�

Power factor Range of values

Excess factor 1...3

3�3�3�- RESTRICTION MODE

If, on the other hand, the micro-grid is in the power limiting mode, the Dispenser will reduce the maximum power available for consumption, also reducing the power that the user can consume.

The Limiting factor parameter has been dened in the DISPENSER-SOFT application as a multiplier factor that reduces the value of the maximum power available for consumption.

Dispenser Universal System

3.4.- OPERATING MODES

The Dispenser can work in two operating modes:

Frequency mode�  Schedule mode�

3�4�1�- FREQUENCY MODE

With the frequency mode activated, the power and energy factors and the status of the aux- iliary relay are programmed according to the frequency of the grid at each moment.

3�4�2�- SCHEDULE MODE

NB: The schedule mode is selected automatically if the frequency mode is not enabled.

The schedule mode is based on the denition of the conditions under which the micro-grid will operate, according to the time of day.

With DISPENSER-SOFT, the operator can dene up to four conditions and distribute them in four daily time zones.

The user can dene up to six types of day (working day, holiday, etc.) and four types of season (rainy season, dry season, etc.) in order to improve energy management efciency.

Instruction Manual

Dispenser Universal System

3.5.- TARIFF SYSTEM

The unit features a tariff system composed of four different types of contracts. This system is responsible for fully adapting to the needs of each customer. The user will nd specic and common parameters associated with each type of contract.

Figure 10:Hydraulic diagram of the tariff system�

The hydraulic diagram shown in Figure 10 provides a general description of how the tariff system of the Dispenser works. Not all tariffs include all the elements of the diagram and the customer must select the tariff that best suits their needs.

There are four types of contracts:

 Type 1: Flat rate for power, where the user is only limited by the instantaneous power they are consuming.

 Type 2: Purchase of energy units. The customer prepays for the energy units. When these are consumed, the power supply is cut off and the customer must purchase additional units.

Type 3: Purchase of EDA units. This contract is similar to the previous type, but the customer has an additional tank (EDA tank with EDA units), which provides additional

Instruction Manual

Dispenser Universal System

management features when purchasing energy.

Type 4: EDA Flat rate. In this type of contract, the customer can consume a daily av- erage amount of EDA units, which are only limited by the contracted power of the user. Unlike the type 3 contract, the customer pays for the days of service. When this period ends, the unit cuts off the power supply

All contracts have a power limit and a validity expiry date, i.e., if they are not activated before this date, the Dispenser will not recognise the contract and not close the circuit breaker.

3�5�1�- TYPE 1 CONTRACT: FLAT RATE FOR POWER

Figure 11:Hydraulic diagram of Type 1 contracts

In the case of type 1 contracts, the customer freely consumes energy and is only limited by the contracted power and power factors, which are applied according to the operating mode of the micro-grid.

When the user exceeds the contracted power, the unit opens the general relay, cutting off the power supply to the user.

To recover the power supply, the user must switch off some of its loads and press the button of the unit. The unit will cut off the power supply within a few seconds if these loads are not switched off and the user presses the button.

Instruction Manual

Dispenser Universal System

The contracted power can be dynamically modied according to the customer's needs. To do so, the customer must contact the operator of the DISPENSER-SOFT and update their contract.

The contract has an expiry date expressed in a number of days. After this period of days, the Dispenser will open the general relay, cutting off the power supply. To recover it, the subscriber must pay the operator of the DISPENSER-SOFT for additional days of service.

Days of service can be accumulated, i.e., if only 3 days remain before the expiry of the contract and the Dispenser is updated with a new contract (an additional 10 days), these days will be added to the remaining number of days in the customer's current contract.

This type of contract can have no denite time limit, Open-ended contract, with no additional costs included in the price of energy. Designed for buildings that are not charged for the use of energy, such as cultural centres, churches, etc.

3�5�2�- TYPE 2 CONTRACT: PURCHASE OF ENERGY UNITS

Figure 12:Hydraulic diagram of Type 2 contracts

3�5�2�1�- CONCEPTS : ENERGY UNITS AND NET METERING

The energy unit concept has been dened in the Dispenser Universal as the units that the customer must purchase from the operator of the micro-grid to receive energy.

Instruction Manual

Dispenser Universal System

The net metering concept is applied to customers that have their own self-powered generator (usually a solar power generator).

Customers with a self-powered generator can consume the energy that is self-generated instantaneously. However, excess production of energy might not need to be consumed during some times of day. This is when the surplus energy can be injected into the electrical network of a micro-grid and the Dispenser will reward the user by adding energy units that can be con- sumed later. This surplus energy injected into the grid is subject to the operating mode of the micro-grid at the time of injection. The unit can measure the injected energy and manage it:

Applying penalties to energy injected during bonus periods.

Awarding a bonus to energy injected during restriction periods.

Example of net metering:

A subscriber installs solar panels at their home to generate their own electricity. At a certain time of day, the amount of energy generated by these solar panels exceeds the current consumption. In this case, the surplus energy of the panels would be injected into the electrical network of the micro-grid. The Dispenser will apply a penalty or bonus to the injected energy, according to the operating mode of the micro-grid.

Micro-grid operating in the normal mode (Price factor =1):

If 1 Wh is injected into the grid, the Dispenser will add 1 unit of credit to the subscriber.

Micro-grid operating in the bonus mode (Price factor <1):

If 1 Wh is injected into the grid, the Dispenser will add <1 unit of credit to the subscriber. If the price factor is 0.8, 0.8 units will be added to the user and not 1, since the micro-grid is operating in the bonus mode and needs no additional energy.

Micro-grid operating in the restriction mode (Price factor >1):

If 1 Wh is injected into the grid, the Dispenser will add >1 unit of credit to the subscriber. If the price factor is 1.5, 1.5 units will be added to the user and not 1, since the micro-grid is operating in the restriction mode and needs additional energy, applying a bonus for the subscriber for the injected energy.

3�5�2�2�- ENERGY BLOCKS CONCEPT

In the energy block operating mode, the price of energy varies according to the consumption.

The user can dene 3 energy blocks through DISPENSER-SOFT, selecting the following for each block:

- The price of energy of each block ( Price factor).

- The consumption after which the system skips to a different block (Energy).

Instruction Manual

Dispenser Universal System

The period of operation of the energy blocks must also be selected (daily, weekly or monthly). When this period ends, the energy meter resets the value of consumed energy to start consuming from Block 1, where energy is cheaper.

Figure 13:Energy blocks�

NB: If the Dispenser has no active contract when the energy meter is reset, the meter will not be reset and the user will continue consuming energy at the price of the current block.

NB: The energy factors, bonus and restriction factors can be available at the same time when the system is operating in the energy blocks mode.

Example 1: A user in block 2 has an energy price factor of 1�5 (FB). The micro-grid is in the

bonus mode with an energy price factor of 0�8 (FM). The nal factor applied to the subscriber will be:

Energy price factor of the customer = FB * FM = 1.5 * 0.8 = 1�2

If you take into account that 1 Wh = 1 unit, when the customer consumes 1 Wh, the Dispenser will subtract 1�2 units (1.2 Wh)

Example 2: Now let us assume that the customer is in energy block 3 with an energy price factor of 2 (FB). The energy levels of the micro-grid are low at this moment and it is operating in the energy restriction mode, with a price factor of 1�4 (FM). The nal factor applied to the subscriber will be:

Energy price factor of the customer= FB * FM = 2 * 1.4 = 2�8

Therefore, when the customer consumes 1 Wh, the dispenser will subtract 2�8 units.

Instruction Manual

Dispenser Universal System

3�5�2�3�- OPERATION

In the case of type 2 contracts, there is a large unit tank that is lled when units are purchased from the operator or through net metering.

The customer has a credit balance expressed in units, which is consumed in 2 ways (binomial tariff):

 by consumed units.

 by xed price, this xed price is subtracted every hour and is recalculated according

to the following equation:

Fixed price = (Price of contracted power x Contracted power ) + Net metering access charge + Other costs

Units

In nominal conditions 1Wh = 1unit

Figure 14:Representation of the consumption in the unit tank

Two energy meters are used to control the unit tank:

 a unit meter, which measures the units in the tank. These units will decrease as the subscriber consumes energy and increase when units are purchased from the operator or through the net metering balance. Under normal conditions, the 1Wh to 1 unit ratio is 1:1.

an energy block meter, which is used when the price of energy depends on the con- sumption level of the user during a period of time.

Instruction Manual

3�5�3�- TYPE 3 CONTRACT: PURCHASE OF EDA UNITS

Dispenser Universal System

Figure 15:Hydraulic diagram of Type 3 contracts

3�5�3�1�- EDA UNIT CONCEPT

The EDA is dened as the Energy Daily Allowance. And the base EDA is dened as the minimum energy available during one day.

Figure 16: EDA and BASE_EDA

Instruction Manual

Dispenser Universal System

The operator must dene the value of the BASE EDA in Dispenser-Soft

The value of the EDA can vary according to the operating mode of the micro-grid with the bonus and restriction factors.

Continuing with the water tank analogy, the EDA concept corresponds to the lling speed of the water tank.

The EDA tank can be lled in two ways:

 Once a day, at the time established by the customer.

 With dripping systems. When this option is selected, the tank lling speed can be

calculated with the formula shown in Figure 17�

Figure 17:Filling speed of the EDA tank

3�5�3�2�- DEFINITION OF THE SIZE OF THE TANK

Users of a micro-grid can have tanks of different sizes.

Therefore, the EDA_CAP is dened as the nominal capacity, i.e., the number of EDA units that can be stored in a tank.

Nominal CAPACITY = EDA_CAP x EDA

3�5�3�3�- OPERATION

The customer has two types of tanks in this type of contract:

the unit tank. the EDA tank.

The energy stored in the EDA tank decreases according to consumption and the xed price and it increases as units are transferred from the unit tank to the EDA tank and according to the net metering values.

Such a transfer of energy from one tank to another varies according to whether the dripping

Instruction Manual

Dispenser Universal System

parameter has been activated or not. When the dripping parameter has been activated, the assigned energy is stored in the EDA tank constantly (every second) and at a rate proportional to that of the contracted energy.

When the dripping option has been deactivated, Compact Dispenser mode, energy is transferred once a day.

The unit opens the general relay when the balance of EDA units is depleted or when the system has been tripped due to an overcurrent.

To recover the power supply, the customer must wait until the EDA tank is lled by means of transferring units from one tank to another or by charging it with EDA units purchased from the DISPENSER-SOFT operator.

If the EDA balance is used up and the tank is filled after activating the dripping option, the general relay will be automatically rearmed, following a reclosing sequence that varies according to the times the power supply has been cut off during the day (See 5.2.4.1.- GENERAL RELAY).

3�5�4� - TYPE 4 CONTRACT: EDA FLAT RATE

Figure 18:Hydraulic diagram of Type 4 contracts�

Instruction Manual

Dispenser Universal System

In the EDA Flat rate mode, the customer can consume an average amount of EDA units which is pre-dened and limited by the contracted power. If the energy daily allowance has not been consumed, it can be stored in the EDA tank up to its nominal capacity, which has been previously programmed in the card.

Unlike type 3 contracts, the customer pays for the days of service and when these end, the customer must purchase additional days of service from the DISPENSER-SOFT operator.

The supply is cut off after this period.
