Simulation on the Application of Electric Spring for Reactive Power Compensation at Load Side

Electric spring has a lot of advantages like simple control and without needing a lot of energy storage, which is applied to the load side by means of suppressing voltage fluctuation caused by the reactive power fluctuation. The simulation model with electric spring is built by using the software of Matlab/Simulink. Through observing the changed voltage waveform on power grids with or without electric spring, the simulation results show that the electric springs are capable of regulating voltage at the load side.
