Power calculation method used in wireless parallel inverters under nonlinear load conditions

Droop control method is widely used in wireless parallel inverters control strategy. In this application, inverters output active power and reactive power need to be calculated accurately for control of the angular frequency and amplitude of output voltage. Traditional calculation methods have a slow and oscillating transient response and could be easily impacted by disturbance and variation of load. To overcome these limitations, this paper suggests an more suitable method of power calculation to increase calculating speed and improve the dynamic response especially under nonlinear load conditions.
