Abstract
At present, the market-oriented reform of comprehensive energy based on electric power is gradually promoted, and it is the general trend for regional comprehensive energy system to participate in market competition. In this paper, we model the bilateral energy trading of regional integrated energy system (RIES) based on Stackelberg game theory. RIES implements power-price curves and time-variant energy prices to conduct interaction with the supply side and the demand side respectively. Then, the energy hub (EH) modeling method is used to build the RIES dispatching model in detail to optimize the operation of RIES to maximize RIES's profit. Nash equilibrium solution is proposed. The simulation results show that the solution of the proposed game interaction model has good convergence, and RIES can better achieve operational optimization of their own distributed energy equipment and purchase energy at a lower cost.
