How do energy management systems work?

Coordination of multiple grid energy storage systems that vary in size and technology while interfacing with markets, utilities, and customers (see Figure 1) Therefore, energy management systems (EMSs) are often used to monitor and optimally control each energy storage system, as well as to interoperate multiple energy storage systems.

What is an Energy Management System (EMS)?

Energy management systems (EMSs) are required to utilize energy storage effectively and safely as a flexible grid asset that can provide multiple grid services. An EMS needs to be able to accommodate a variety of use cases and regulatory environments. 1. Introduction

How do energy storage systems maximize revenue?

In these regions the potential revenue of ESSs is dependent on the market products they provide. Generally, the EMS tries to operate the ESS to maximize the services provided to the grid, while considering the optimal operation of the energy storage device. In market areas, maximizing grid services is typically aligned with maximizing revenue.

What are the requirements for a communication interface of an ESS?

Fundamental requirements for a communication interface of an ESS can be found in existing standards such as IEC 61850-7-420 and Modular Energy System Architecture (MESA) (see Figure 5). Commercial systems often follow standardized communication protocols.

Which microcontroller is used for battery management firmware?

For demonstration purposes a Microchip© 8-bit microcontroller was used as the host for the battery management firmware, the code was written in ANSI C language and developed within MPLAB studio environment. The firmware is simple with three main functions: a power state-machine, sensor measurement and communications.

Do energy storage devices need a PCs?

The majority of energy storage devices employ a direct current (DC) interface. Therefore, a PCS is required to integrate with the alternating current (AC) power grid. The purpose of the PCS is to provide bi-directional conversion and electrical isolation.
