What is battery energy storage system (BESS)?

Battery energy storage system (BESS) has been applied extensively to provide grid services such as frequency regulation, voltage support, energy arbitrage, etc. Advanced control and optimization algorithms are implemented to meet operational requirements and to preserve battery lifetime.

What is a battery energy storage system?

Battery Energy Storage Systems (BESS) are expected to be an integral component of future electric grid solutions. Testing is needed to verify that new BESS products comply with grid standards while delivering the performance expected for utility applications.

What is 'grid scale' battery storage?

This guidance document is primarily tailored to ‘grid scale’ battery storage systems and focusses on topics related to health and safety. There is no specific definition of ‘Grid Scale Storage’ however for the purposes of this guidance document, this is assumed to be systems with an installed capacity of 1MW or greater.

What is a battery energy storage system (BESS) Handbook?

This handbook serves as a guide to the applications, technologies, business models, and regulations that should be considered when evaluating the feasibility of a battery energy storage system (BESS) project.

How are grid applications sized based on power storage capacity?

These other grid applications are sized according to power storage capacity (in MWh): renewable integration, peak shaving and load leveling, and microgrids. BESS = battery energy storage system, h = hour, Hz = hertz, MW = megawatt, MWh = megawatt-hour.

What is grid interconnection type testing?

Grid interconnection type testing is used to verify that the battery energy storage system properly performs its application logic and complies with grid interconnection standards (such as IEEE 1547) over its entire operating range. This testing would be performed with a test lab setup with the equipment and monitoring links as shown in Figure 3.
