Regional Coordinated Voltage Regulation in Active Distribution Networks With PV-BESS

In distribution networks with a high penetration of photovoltaic (PV), the intermittency is easy to cause regional voltage violation issue. Network-wide power compensation is always used to mitigate this issue while lacking a regional refined voltage regulation (VR). This brief proposes a regional c...

Zusammenfassung:In distribution networks with a high penetration of photovoltaic (PV), the intermittency is easy to cause regional voltage violation issue. Network-wide power compensation is always used to mitigate this issue while lacking a regional refined voltage regulation (VR). This brief proposes a regional coordinated VR algorithm that uses a proportional power compensation of PV inverter and battery energy storage system (BESS) based on the sensitivity. With a shared VR burden among all PV inverters and BESSs, the regional voltage violation issue is solved without using network-wide controllable resources. Finally, the simulation results demonstrate the effectiveness of this algorithm.
