Improved droop control strategy based on voltage feedforward current compensation

In order to achieve the stable operation of different-capacity parallel distributed generators, this paper proposes an improved droop control strategy according to the control strategy of parallel synchronous generators. By the improved control strategy, the active power and reactive power of parall...
