Abstract :
This paper proposes a stationary-frame control method for voltage unbalance compensation using Interline Photovoltaic (I-PV) power system. I-PV power systems are controlled to compensate voltage unbalance autonomously. The control system of I-PV plants mainly consists of active and reactive power droop controllers, voltage and current controllers and unbalance compensator. This approach is based on injecting negative sequence current from I-PV power plants to compensate for the unbalanced loads. Consequently, the Point of Common Coupling (PCC) voltage remains balanced and regulated. The results obtained from Matlab/Simulink based simulation demonstrate the effectiveness of the proposed method in compensation of voltage unbalance at PCC.
