In recent years, the increasing penetration of photovoltaic (PV) systems has caused power quality issues in distribution systems, including voltage rises due to reverse power flows and rapid voltage fluctuations. Conventionally, voltage management has been performed using grid-side equipment. However, relying solely on such equipment to mitigate PV output uncertainty is becoming increasingly difficult and may increase the operational costs of the power grid.
To address this challenge, coordinated voltage management using demand-side resources, such as PV grid-connected inverters and controllable loads, has attracted attention. Since this approach relies on consumers' participation, appropriate incentive mechanisms are required to encourage and sustain their cooperation.
Cooperative game theory provides a well-established framework for fairly allocating the benefits generated through cooperation and has been widely applied in power system studies. In this paper, a coordinated voltage management method for distribution systems with high PV penetration is proposed, achieving stable cooperation among prosumers through fair profit allocation.
