1 Scope
This part of IEC SRD 63443 covers the terms and definitions, system architecture, and service
scenarios of distributed energy resource aggregation business (ERAB), whose definition is to
restrain or elevate the power generation of distributed energy resources (DERs) and power
demands of controllable loads (CLs) at customer premises in accordance with the performance
measurement by the metering device at the point of common coupling (PCC), allowing real-time
data access from customer premises and the request of the transmission service operator
(TSO), distribution system operator (DSO), electricity supplier, and energy exchange, as
illustrated in Figure 1.
Figure 1 – Position of ERAB system
In conventional power systems, the balance between supply and demand is adjusted by the
transmission service operator (TSO) and distribution system operator (DSO) controlling the
power generation facilities on the supplier side, enforcing the same amounts of demand and
supply at the same time on TSO and DSO. However, the widespread use of DERs and CLs with
network access has enabled them to be configured as virtual systems on the demand-side. In
addition, real-time data access to a metering device allows measurement of the performance
of aggregating these devices using trustworthiness data. Similar to the drastic changes in the
electricity system, the ERAB provides a new service scenario that contributes to the balance of
supply and demand within the electricity system.
The ERAB coordinates the requests and reports from/to ERAB participants, such as the TSO,
DSO, and electricity supplier, and manages the remote control of the DERs and CLs executed
through the ERAB controller that provides site-specific DER management. The ERAB provides
two types of services: "demand restraint" and "demand increase." The former model removes
tight supply and demand by effectively shaving or shifting the peak demand. The latter model
contributes to the effective use of energy by shifting the demand against the excessive power
supply owing to the expansion of the introduction of renewable energy, as well as to the
improvement of energy autonomy by aggregating the DERs and CLs with a power storage
function.

4 System component
4.1 General
The decentralised generation of electrical power, as well as the spread of energy storage and
controllable loads, the management of distributed energy resources (DERs), and controllable
loads (CLs) at the customer premises near the final customer offer economic and ecological
benefits. In addition, information on metering data from advanced metering infrastructure (AMI)
provides a customer with a method to measure the value of aggregating these resources at the
customer premises.
Distributed energy resource aggregation business (ERAB) is a system architecture and service
scenario that restrains or elevates the power generation of DERs and demands of CLs by a set
of customer premises in accordance with the performance measurement by metering data at
the point of common coupling (PCC), allowing real-time access from customer premises and
requests by transmission service operators (TSO), distribution system operators (DSO),
electricity suppliers, and energy exchange. The ERAB is configured by the ERAB server that
manages upward communications such as the TSO, DSO, and electricity supplier and ERAB
controller that manages downward communications such as a metering device, DERs, and CLs.
ERAB was mapped onto the smart grid architecture model (SGAM) in IEC TR 63097:2017, as
shown in Figure 2. ERAB servers were placed in the enterprise zone, configuring the ERAB
controller at the field zone with real-time data access to a metering device at the PCC. The
DER and CL at the field zone are operated by the ERAB controller.
Annex A shows use cases of distributed energy resource aggregation business for information.
Figure 2 – Outlook of ERAB on SGAM plane in IEC TR 63097:2017
4.2 ERAB system
In alignment with the hierarchical approach in SRD 62913-2-3:2019, ERAB is described in five
levels across multiple domains, as illustrated by the five-level hierarchical system architecture
shown in Figure 3.
– Level 1: DERs and CLs are at the bottom level and are described as customer premises.
They are operated autonomously in normal time but are incorporated behind the PCC, in
which a metering device allows real-time data access when ERAB is in process. The remote
operation signal is delivered by the ERAB Controller at level 2.
– Level 2: The ERAB controller is at a higher level in which the operation of the DERs and
CLs and the metering data at the PCC are managed. The controller has been recognised
as a logical function in the field zone in SGAM, so that it appears in commercial and
industrial sites, such as households and buildings.
– Level 3: The ERAB server requests and commands the DERs and CLs through the ERAB
controller that performs specific actions, such as turning on/off and increasing/restraining
the output. The signal managed by the ERAB server, for example, DR, is in accordance with
the commands by the user of ERAB such as, TSO, DSO, electricity supplier, and energy
exchange.
– Level 4: The utility operational grid management in DSO/TSO applies to utility applications
that are required to determine what commands should be issued to the ERAB servers.
– Level 5: Market operations involve a large-energy environment. For example, a balancing
power market is a bid/offer transaction energy market between ERAB and TSO/DSO.
Figure 3 – ERAB on the five-level architecture in IEC SRD 62913-2-3:2019
4.3 ERAB controller
The ERAB controller collects data from the metering device at the PCC, controls various DERs
and CLs, and communicates with them. The controller provides the following key functions:
– data ingestion, cleaning, filtering, positioning, and early analytics before being sent to a
cloud or remote data centre;
– security as a network gateway acts as a buffer between a WAN and devices on customer
premises;
– provision of real-time configuration, control, management, and tracking.
4.4 Distributed energy resource
Distributed energy resource (DER) is a generator (with its auxiliaries, protection, and
connection equipment), including loads with a generating mode (such as electrical energy
storage systems) connected to a low-voltage or medium-voltage network.
4.5 Controllable load
Controllable load (CL) is the load of particular consumers that shall be reduced for a limited
period of time under contract at the request of the distribution supply undertaking. The
controllable loads in ERAB include air conditioning, lighting, and other loads. The controllable
loads exchange information with an aggregator through ERAB, uploading their status and
responding to a control signal such as DR.
4.6 Metering device
A smart metering device is essential for the ERAB. The data accuracy collected at the metering
device ensures the performance of the ERAB, which manages the DR orders from the TSO,
DSO, and electricity supplier. To trade electricity in the ERAB, a metering device measures the
active power at the PCC. Its data interval, for example, every 1 min and 30 min, is in accordance
with the service menu between ERAB and its users. The real-time data access between the
ERAB controller and metering device at the PCC is mapped on the five-layered architecture in
IEC SRD 62913-2-3:2019, as shown by Figure 3.
5 Evaluation of the value of ERAB
5.1 Evaluation pattern of ERAB
To evaluate the value created in the ERAB, it is necessary to define the evaluation procedures
shown by the measurement items (location, interval), criteria (kW and kWh), and time. This
procedure is implemented using the data accessible to a metering device at the PCC. Table 1
illustrates the necessary evaluation items for ERAB as well as the reward/penalty mechanism.

5.2 Measurement point of ERAB value
5.2.1 General
In general, there are two measurement points for evaluating the amount of supply under control:
point of common coupling (PCC) and DER point measurement. ERAB applies PCC
measurements while also considering DER point measurements for future adaptation.
5.2.2 PCC point measurement
As shown in Figure 4, the point of common coupling (PCC) is a point in an electric power system,
electrically nearest to a particular load, at which other loads are, or can be, connected. The
PCC measurement is applicable for the trade of adjusting power at the energy exchange as
well as the ERAB. The necessary metering data available at PCC is shown in Table 2 for general
purpose, Table 3 for low-voltage customers, and Table 4 for high-voltage customers.

5.2.3 DER point measurement
The DER point measurement is a method of measuring at a point other than the receiving point.
Figure 5 shows a case in which a meter is embedded in the DERs and CLs. In this measurement,
the performance of ERAB is measured at the point of DER and CL. It is possible to adopt the
DER point measurement only when there is an agreement between ERAB users.

Figure 5 – DER point measurement
5.3 Evaluation standard of ERAB value
5.3.1 Evaluation standard applicable to lowering DRs
Where consideration is paid to the controlled amount of ERAB (amount of electricity delivered
by control, which is measured by kWh and kW values), an evaluation standard is highlighted.
The difference between the amount of electricity that would be expected in the absence of a
control mandate (hereinafter referred to as "baseline") and the actual amount of electricity when
the ERAB is working is evaluated. While the baseline is set on a per-customer basis, there is
nothing preventing ERAB from grouping multiple customers together when setting the baseline.
As a definition of the controlled amount, the controlled amount in a forward power flow is the
"demand-reduced amount". A baseline that can be agreed upon among the concerned parties
of the ERAB is required. The concept behind the controlled amount in incentive-based DR (DR
lowering) is shown in Figure 6.

Figure 6 – Baseline
There are some methods on baseline calculations. For example, the baseline of the high 4 of 5
that presents the total average value for the five most recent days, exclusive of excluded days
is applicable for reducing demand amounts. The temperature of the day, as well as other events,
is an element of the baseline. The average value of the demand data is based on the active
power value in a thirty-minute block accessible at a metering device in the PCC. The demand
data for the four days with the highest average demand amount during the DR in the
implementation period out of the five days prior to a DR is the implementation date (excluding
the date of DR implementation). If there are multiple days with the lowest average demand
amount during the DR implementation period over the five prior days, we exclude the day
furthest from the DR implementation date and use the remaining four days.
5.3.2 Evaluation standard applicable to demand-generating DRs
Demand-generating DR increases the use of grid electricity by reducing the amount of electricity
generated by power-generation resources and charging energy-storage facilities located behind
the meter at the PCC. The high 4 of 5 (with adjustments made on the day in question) is
applicable as a baseline as well as for the lowering DR. The baseline for elevating DRs shall
be set forth through discussions by and among the concerned parties based on the state of
performance of the elevating DR in question.
5.3.3 Evaluation time
The evaluation time is subject to a controlled evaluation. Whether the time subject to an
evaluation is not just the duration from the time at which control commences to the time at which
control ends, but also includes the start-up time (time from when the mandate is issued to when
the duration commences) and recovery time (time from when the duration ends to when normal
operations resume) shall be determined through discussions among the concerned parties, as
shown in Figure 7.
Figure 7 – Definitions of different time categories related to DRs
5.3.4 Evaluation interval
The interval for evaluating the controlled amount should be subject to agreement among units
of 30 min.

A.1.2.3 Scope and objectives of use case
Scope and objectives of use case
Scope Decentralized generation of electrical power, as well as the spread of energy storage and
controllable loads, has become increasingly important. The management of these distributed
energy resources (DERs) and controllable loads (CLs) at customer premises near the final
customer offers economic and ecological benefits. In addition, information on metering data,
including advanced metering infrastructure (AMI), provides a customer with a method to
measure the value of aggregating these resources at customer premises.
The distributed energy resource aggregation business (ERAB) restrains or elevates power
generation of distributed energy resources (DERs) and power demands of controllable loads
(CLs) at customer premises in accordance with the performance measurement by the
metering device at the point of common coupling (PCC), allowing real-time data access from
customer premises and the request by the transmission service operator (TSO), distribution
system operator (DSO), electricity supplier, and energy exchange.
NOTE For a definition of a virtual power plant (VPP), refer IEC TS 63189-1.
Objective(s) The business use case describes how distributed energy resource aggregation business
(ERAB) works accordingly to the request by TSO, DSO, electricity supplier, and energy
exchange.
