Dynamic Performance of Reactive Power Control for Voltage Support in Low-Voltage Distribution Networks with Photovoltaic Systems

Abstract:

The coordinated reactive power control among photovoltaic (PV) systems, without communication requirement, is introduced to prevent the over-voltage problems in radial distribution networks. The voltage source inverter in PV system can provide the reactive power control to deal with the dynamic voltage variations. Two reactive power control methods, Q(P) and Q(V), can be employed into each PV system depending on its location. The dynamic voltage control performances are examined on simulation in DIgSILENT PowerFactory software. The results showed that the proposed control method can mitigate the rise of voltage level sufficiently.
