在考虑信息传递延迟产生费用基础上,设计一种新的电力用户社会福利函数来构建智能电网下多售电商多用户的Stackelberg博弈模型,证明了电力用户之间及售电商之间非合作博弈纳什均衡的存在性,从而得到售电商与用户之间的Stackelberg博弈均衡。最终提出一种分布式迭代算法求解用户最优用电策略和售电商的最优实时定价策略。数值模拟验证了算法的收敛性,获得了售电商最优实时定价策略,从而说明该定价机制的合理性与有效性。
Based on the consideration of information transmission delay cost, a new power user social welfare function is designed to construct the Stackelberg game model of multi-selling multi-user under smart grid, which proves that non-cooperation between power users and salespersons Game Nash equilibrium existence, thus obtaining the Stackelberg game equilibrium between the salesman and the user. Finally, a distributed iterative algorithm is proposed to solve the optimal real-time pricing strategy of the user and the electricity supplier. The numerical simulation verifies the convergence of the algorithm and obtains the optimal real-time pricing strategy for the salesman, which shows that the pricing mechanism is reasonable and effective.
