Abstract
A new method for islanding detection is presented, and the status of the islanding can be detected by the change of the frequency of the load voltage. The optimal detection performance is achieved when the appropriate RPC (reactive power compensation) strategy is used, which is in accord with the characteristics of the loads. The theory of the islanding detection using the variable reactive power generation from the inverter is investigated primarily. The simulation results validate the feasibility of the RPC method to detect the islanding. At last, the effects of the matching degree of the active power and reactive power between the power resource and the local loads on the frequency of the load voltage are analyzed by the simulation results.
