Power consumption strategy in smart residential district with PV power based on non-cooperative game

Abstract

With the popularization of intelligent household appliances, the interactions between electric market and customers have become more frequent. Because of Photovoltaic(PV) power intermittency, the customers are encouraged to participate in PV consumption. This paper proposes an optimal smart power utilization model using a non-cooperative game for residential community with distributed PV energy. Firstly, a benefit maximization model for distributed PV energy is established to determine an optimal PV output. Secondly, according to the consumption habits and load curves of residential customers, a power utilization model of community customers is built by clustering analysis. Finally, a non-cooperative game model between PV power supplier and customers in the community is built, and a Nash Equilibrium point is obtained based on the balance between maximum benefit of PV power and minimum electricity bills for customers, which is useful to encourage the consumers to consume PV energy in local areas. The proposed model can not only achieve the maximum benefit of PV power, but also reduce customers’ electricity payments, which is indicated in case studies.
