Abstract:

© 2015 IEEE. Microgrids performance and stability mostly depend on power flow control strategy. In order to allow for a coordinated control while maintaining a reliable operation, decentralized control methods based on P and Q droop characteristics have been utilized. Originally based on the conventional power systems, the power droop control methods, suffer from inherently slow dynamics. In this paper, a novel control method based on V-I characteristics is introduced to exploit the flexibility and fast dynamics of the inverter based Distributed Energy Resources (DERs). In this method, the direct and quadrature axis voltage components are drooped with the corresponding currents according to a piecewise linear droop function. The proposed method significantly improves the system dynamic response by increasing damping and decreasing time constant. In order to verify the efficacy of the proposed method, simulation results are presented.
