Why is energy storage important in electrical power engineering?

Various application domains are considered. Energy storage is one of the hot points of research in electrical power engineering as it is essential in power systems. It can improve power system stability, shorten energy generation environmental influence, enhance system efficiency, and also raise renewable energy source penetrations.

Why do we need energy storage systems?

and the electrification of transportation and heating systems. As a consequence, the electrical grid sees much higher power variability than in the past, challenging its frequency and voltage regulation. Energy storage systems will be fundamental for ensuring the energy supply and the voltage power quality to customers.

Why do energy storage systems need a DC connection?

DC connection The majority of energy storage systems are based on DC systems (e.g., batteries, supercapacitors, fuel cells). For this reason, connecting in parallel at DC level more storage technolo-gies allows to save an AC/DC conversion stage, and thus improve the system efficiency and reduce costs.

What is a battery energy storage system?

A 100kW, 200kWh battery energy storage system, that is based on distributed MMC architecture. A battery module is connected directly to the half-bridge cell of the MMC, working both for control and energy storage purposes.
