INTRODUCTION
Microgrids can serve various purposes depending on the primary objectives of their applications.
They are usually seen as a technical means to manage reliability of supply and to facilitate local
optimization of energy supply by controlling distributed energy resources (DER). Microgrids
also present a way to provide electricity supply in remote areas, to use renewable energy as a
systematic approach for rural electrification and to increase resiliency and security of supply to
end users.
IEC TS 62898 series is intended to provide general guidelines and technical requirements for
microgrid projects.
IEC TS 62898-1 mainly covers the following issues:
• determination of microgrid purposes and application,
• preliminary study necessary for microgrid planning, including resource analysis, load
forecast, DER planning and power system planning,
• principles of microgrid technical requirements that should be specified during planning
stage,
• Microgrid evaluation to select an optimal microgrid planning scheme.
IEC TS 62898-2 mainly covers the following issues:
• operation requirements and control targets of microgrids under various operation modes,
• the basic control strategies and methods under various operation modes,
• the requirements of electrical energy storage (EES), relay protection, monitoring and
communication under various operation modes,
• power quality.
IEC TS 62898-3-XX subseries technical specifications deal with the technical requirements of
microgrids.
IEC TS 62898-3-1 covers the protection and dynamic control of microgrids.
The present document covers microgrid energy management systems (MEMS).

4.1 System architecture and functional mapping
Generally, microgrids can be integrated into the electric power system (see Figure 1), and
MEMS is one of the key components or functions of microgrid. Figure 1 is based on a general
view and the displayed blocks have other possibilities depending on the size of the microgrids
and the type of applications.
Figure 1 – Conceptual map of a power system consisting of a microgrid
The operation control system of a microgrid can be divided into three layers according to the
time scale, namely the energy management layer, the monitoring and control layer, and the
protection and dynamic control layer, see Figure 1.
Figure 2 – Functional mapping for operation and control of microgrids
The protection and dynamic control layer of the operation control system of microgrids is not
handled by the microgrid energy management module as an independent module since this
layer is mainly for real-time control of DER, and its response time is the shortest.
The energy management works mainly in energy management layer and partially in the
monitoring and control layer for small size microgrids. In Annex A, MEMS functions are
performed or detailed in some actual application cases.
– 14 – IEC TS 62898-3-2:2024 © IEC 2024
For small microgrids, MEMS and MMCS could be managed by the same microgrid controller
(see 4.4.2, Figure 4).
The following two documents are very important for LV prosumer installations and for microgrid
as well:
• IEC 60364-8-82, which provides more detailed requirements regarding low voltage
prosumer electrical installation.
• IEC TS 60364-8-3, which provides more detailed consideration regarding low voltage
prosumer electrical installation.
The protocol conversion in MEMS should be based on the same principle as described in
IEC 61970-1:2005; see also Annex B of the present document.
4.2 Stand-alone MEMS
Microgrid energy management as a stand-alone system is intended to handle only the operation
and control system of microgrids. It is configured to have the functions with long time scales,
such as power generation forecasting, economic dispatching, and demand side management.
4.3 Integrated MEMS
Microgrid energy management module as a system integrated into a microgrid controller is
intended to handle the operation and control system of microgrids and partly the monitoring and
control layer. It is configured to have functions with long time scales, such as power generation
forecasting, economic dispatching, and demand side management. It can have fast response
times, usually involving data acquisition, system operation mode switching, black start, and
emergency control.
4.4 Communication protocols and cyber security
4.4.1 Basic principle
The microgrid should have reliable information communication capabilities. The communication
protocol and communication medium should be configured according to the specific application
scenarios, real-time requirements, and the actual situation on site.
4.4.2 Recommended methods
The microgrid communication involves remote communication and local communication. The
remote communication is applied for information exchange between the microgrid and the
upstream grid dispatching system called "dispatch centre", and the local communication is
applied for information exchange among MEMS, microgrid control and monitoring systems, DER
and/or other internal equipment of microgrid. In the case of an isolated microgrid, i.e., it is not
connected to an upstream main grid, there is no need for communication link with a dispatch
centre (dotted point lines in Figure 3 and Figure 4).
The communication protocols shall be defined according to interoperability requirements. For
example, the communication protocol can be the IEC 61850 series, IEC 60870-5-104,
IEC 60870-5-101 and IEEE Std 1815.
For local communication, the number of layers depends on the structure of the microgrid
management system.
Usually, a part of MEMS functions is carried out in the cloud, the communication can be based
for example on Web Services REST protocols.
Local communication for structure 1: Stand-alone MEMS module
Under a three-layer architecture, the protocols of the IEC 61850 series, Modbus and other
protocols can be applied between the microgrid controller and the DER and internal equipment
of microgrid. The selected communication media of the microgrid can be optical fibre, twisted
pair, wireless, etc. according to specific application conditions, see Figure 3.

Local communication for structure 2: Integrated MEMS module
Under a two-layer architecture, the protocols of IEC 60870-5-101, IEC 60870-5-104, DNP3
(Distributed Network Protocol, IEEE Std 1815), etc. can be applied between MEMS and the
microgrid controller, and the IEC 61850 series, Modbus and other protocols can be applied
between the microgrid controller and the DER and internal equipment of microgrid. The
communication medium used for the microgrid can be selected as optical fibre, twisted pair,
wireless, etc. according to specific application conditions. For integrated MEMS modules, digital
and analogue signals using I/O card could also be an option.

4.4.3 Cyber security
The cyber security strategy of MEMS shall be aligned with the IEC 62443 series, which defines
security levels and associated requirements for Industrial Automation and Control Systems
(IACS).
The IEC 62443 series defines four different security levels (SL1 to SL4), with specific
requirements applicable to system level (see IEC 62443-3-3) and component level (see
IEC 62443-4-2). The required level remains specific to each microgrid application and its
required security profile. The manufacturer or system provider shall declare the security level
of the MEMS and its components, as defined in the IEC 62443 series.
Cyber security functions of MEMS should be shared with MMCS (see IEC TS 62898-3-4), and
the declared security level can be common.

The configuration and main functionalities of MEMS shall be based on the selected type,
purpose, use case, application, target and needs of th
