Battery storage system for frequency stabilization of ac networks with high penetration of renewable power

الملخص EN

This paper investigates the uses of battery energy storage system (BESS) in ac networks highly populated with wind power generation.

The investigation includes power system load levelling, frequency stabilization, and provision of reactive power support to the wind farm network.

The BESS is connected to the wind farm main hub via voltage source converter, while the wind farm is connected to ac network modelled with detailed synchronous generator, including excitation and turbine-governor control.

In general the paper attempted to study the role of BESS in modern power system regarding improving system stability.

Time-domain simulations conducted in Matlab/Simulink are used to validate the importance of the BESS.
