Introduction

This document should be used for general specification purposes only. The final solution design is based on the customer project requirement.

The design of each Microgrid project varies based on size, power and voltage levels, types of Distributed Energy Resources (DER), electrical loads, and environmental factors. The environmental factors, such as location, climate, standards and regulations, utility interconnection requirements, local energy pricing, physical layout, main drivers, and cost criteria, are project-specific and define the solution's design.

Hence, a preliminary engineering study should be performed by Schneider Electric or a third party, to model the physical and economic environment and context. The study helps the engineering team in determining the types and power ratings of the Microgrid components to be used and aids in proposing the appropriate technical design and configuration of the EcoStruxure Microgrid Operation Large solution.

Overview

EMO-L is a Microgrid controller. Microgrid and DER technologies are increasingly chosen by the energy industry as the strategy to provide cost-effective, resilient, and adaptable supply of sustainable energy. With Microgrids, DER can operate in parallel with the grid or selectively islanded in the event of electricity outage or to reduce energy cost.

A Microgrid is a managed group of DER such as:

Energy production sources for example, solar panels, combined heat and power facilities (CHP systems), gensets and so on.
Energy storage systems for example, Battery Energy Storage System (BESS), thermal energy storage system and so on.
Shed able loads that can be shed during an outage.

Features

EMO-L is a controller with dedicated HMI which allows the monitoring and control of the DER systems within the Microgrid.

EMO-L offer comprises of:

Microgrid Controller
HMI: Ecostruxure Power Operation or EPAS-UI.

The features of EMO-L Microgrid are:

Ensure the stability of the Microgrid by synchronizing the energy production sources, loads, and energy storage systems based on the energy requirement.
Automatically disconnect and re-connect the Microgrid from or to the grid (islanded mode or grid-connected) in case of abnormal electrical conditions such as grid blackout.
Maintain the frequency and voltage in the Microgrid during islanded or off-grid mode within an acceptable operating range.
Perform dynamic electrical topology computations in real time to manage the energy production or consumption.
Adapt the power production of each DER.
Shed non-critical loads when the Microgrid power production is lower than the demand.
Island management of the Microgrid.
Real-time control of DER.
