This paper proposes an interline power flow control method using photovoltaic (PV) plant for both transmission and distribution networks in order to regulate the feeder voltages. In the proposed approach the interline power flow between two or more feeders will be achieved by appropriately reconfiguring the PV plant. The reconfiguration is made in such a way that the PV plant acts as a flexible ac transmission system (FACTS) device to regulate the point-of-common coupling (PCC) voltage on either feeder. The control system of I-PV plants mainly consists of active and reactive power droop controllers, voltage and current controllers and unbalance compensator. The negative sequence current is injected from the I-PV power plant to compensate for the unbalanced loads. In addition to voltage regulation, active and reactive power flow control and energy management in a multi-line system can be achieved using the proposed method. The simulation of the proposed model was carried out using MATLAB/Simulink and the effective performance was analyzed.
