Study on Droop Control Strategy with Application to Flywheel Energy Storage System

Abstract:

The flywheel energy storage technology is a kind of method that converts electrical energy into kinetic energy in store. The flywheel energy storage system (FESS) is usually used for renewable energy system such as wind turbine generator system (WTGS) to adjust the quality of output power. Droop control is a kind of control technology to regulate the active power and reactive power in micro-grid. In this paper, we introduced a method to combine the droop control with FESS and designed the control topology. The droop control method was applied to control the part of inverter in FESS. By controlling the output frequency and the voltage amplitude of WTGS-FESS system, we can regulate the output of the inverter as a promotion in smoother active power and reactive power.
