Abstract

Energy management systems are one of the most important components in the operation of an electric microgrid. They are responsible for ensuring the supervision of the electrical system, as well as the coordination and reliability of all loads and distributed energy resources in order for the microgrid to be operated as a unified entity. Because of that, an energy management system should be fast enough at processing data and defining control action to guarantee the correct performance of the microgrid. This paper explores the design and implementation of an energy management system deployed over a dedicated electronic device. The proposed energy management device coordinates the distributed energy resources and loads in a residential-scale islanded microgrid, in accordance with a rule-based energy management strategy that ensures reliable and safe operation of the battery-based energy storage system. A hardware-int-he-loop test was performed with a real-time simulation platform to show the operation of the electronic device

Highlights

Increasing energy requirements, along with a general concern about global warming caused by the use of conventional energy sources based on fossil fuels, have triggered the use of renewable energy sources (RES) (Keyhani, 2016)
The model defined for the rule-based management strategy requires the energy management device to perform mathematical operations such as solving a system of equations composed by Equation (2) and (3), which allow obtaining the curtailment indexes of the generators when the microgrid operates in MODE II
This fact minimizes the initial need to have a real system plant, which comprises a system of medium complexity devices in the case of a microgrid

Summary

Introduction

Increasing energy requirements, along with a general concern about global warming caused by the use of conventional energy sources based on fossil fuels, have triggered the use of renewable energy sources (RES) (Keyhani, 2016). The rule-based management strategy will be outlined for an isolated microgrid whose model has been implemented on a real-time simulation platform (OP4510).
