Abstract

Power sharing and load voltage regulation requires the knowledge of feeder impedance which is one of the biggest demerit of conventional droop control. This paper proposes a new method to overcome this demerit by the use of numerical approach and a new voltage regulation technique. Modified angle droop and voltage droop is proposed for intended sharing ratio and transfer of active and reactive powers. The proposed method can work with different type of feeder impedance using a single droop law. Accurate sharing of active and reactive power while maintaining constant load voltage without the knowledge of feeder impedance is the main contribution of this paper. Simulation results are shown to verify the proposed scheme.
