Zusammenfassung:	In this paper, a power control strategy for parallel inverters of DGs, which are connected to harmonic polluted grids, is proposed. In order to optimize the controller performance, the dual-time sampling scheme is implemented. Also, the parameters of the controller are optimized by harmony search algorithm. The simulation results show that by using this scheme the system control delay is minimized, and the proposed controller presents a high performance even under presence of system harmonics or fault.
