Energy storage provides reactive power control

Do outer loop active and reactive power controllers ensure battery energy storage system performance?

Abstract: This paper proposes outer loop active and reactive power controllers to ensure battery energy storage system (BESS) performance when connected to a network that exhibits low short circuit ratio. Inner loops control the BESS current components.

How does a battery energy storage system work?

3.1. Battery Energy Storage System The BESS consists of an active front end (AFE), with a 30 kV A nominal power, connected to the grid and to a DC low voltage bus-bar at 600 V through a DC link supplied by a 20 kW DC/DC buck booster and a Li-Polymer battery with 70 A h and 16 kW h total capacity.

Does reactive power control affect a distribution feeder?

One way to mitigate such effects is using battery energy storage systems (BESSs), whose technology is experiencing rapid development. In this context, this work studies the influence that the reactive power control dispatched from BESS can have on a real distribution feeder considering its original configuration as well as a load transfer scenario.

What are the main energy storage functionalities?

In addition, the main energy storage functionalities such as energy time-shift, quick energy injection and quick energy extraction are expected to make a large contribution to security of power supplies, power quality and minimization of direct costs and environmental costs ( Zakeri and Syri 2015 ).

What is active power control?

The active power control performs a peak shaving logic that has been already tested and explained by the authors in Sbordone et al. (2015). The monitoring and control system read the active and the reactive power in the measurement point.
