In recent years, with the rapid development of photovoltaic power generation and the gradual deepening of research on regional integrated energy system, more and more complex factors need to be considered in integrated energy system planning. In order to promote photovoltaic consumption, a novel model of energy supply system (ESS) for photovoltaic integrated energy system (PIES) is proposed. The Stackelberg game model based on multi-leader and multi-follower is established, and through the internal electrovalence and energy dynamic scheduling game, the high proportion of photovoltaic power generation is achieved on the basis of the minimum energy cost. Taking a regional power grid in northeast China as an example, the results show that the proposed method can effectively improve the local photovoltaic consumption level, and accelerate the pace of carbon emission reduction.
