Multi-energy entities cooperative operation strategy of power system based on stochastic evolution game theory
The randomness and fluctuation of wind and photovoltaic output,as well as the bounded rationality among various energy enti-ties,result in low wind and solar consumption rates.In order to maximize the interests of each energy entity and improve the wind and solar consumption rate,a multi-energy entities cooperative operation strategy of power system based on stochastic evolution game theory was proposed.Firstly,the Wasserstein index was used to build a wind and photovoltaic uncertainty model to obtain the optimal scenario of wind and photovoltaic output.Then,based on the stochastic evolution game theory,the game relationship between the energy power supply station and the load aggregator was analyzed,and the system optimal operation model was established with the goal of minimizing the dispatch cost and pollution cost.Finally,the power system with high proportion new energy in Hexi area of Gansu Province was taken as an example for simulation verification.The results show that the proposed strategy can flexibly suppress the fluctuation of wind and photovoltaic output,improve the consumption rate of renewable energy,and achieve the economic operation of the system.
