基于综合需求响应和博弈的区域综合能源系统多主体日内联合优化调度

Multi-player Intraday Optimal Dispatch of Integrated Energy System Based on Integrated Demand Response and Games

区域综合能源系统是以可再生能源为核心,多能源网络耦合、多利益主体协同的未来能源网络,多方主体间的制约平衡是实现系统优化运行的关键。构建了包含产能基地、系统管理商和综合能源用户三方主体的典型区域IES模型;并建立综合能源用户的热电负荷耦合特性模型,完善综合需求响应机制。基于综合需求响应和博弈方法,提出了一种两阶段优化调度策略,实现区域IES内三方主体利益诉求的制约平衡和日内联合优化。一阶段为系统管理商的经济收益优化,利用Stackelberg博弈和电价型IDR策略实现用户对系统管理商经济优化的制约;二阶段为产能基地与用户利益的联合优化,采用激励型IDR策略建立用户与产能基地的互利关系,利用联盟博弈实现用户间制约平衡,从而实现三方主体利益相互制约和联合优化。最后,通过仿真算例验证了所提调度策略的优越性。

Integrated energy system (IES) is a future energy system focusing on renewable energy, containing multi-energy systems and multiple players. Equilibrium among players is the key point of system optimization. Firstly, an IES model is built, composed of a system manager, a generation base and integrated energy consumers. Then a coupling model between different loads is proposed. On this basis, a complete integrated demand response (IDR) strategy is proposed. Based on IDR and game method, a two-stage optimal dispatch is proposed to realize equilibrium and multi-player intraday optimization. The first-stage dispatch focuses on optimization of system manager profit. The optimization is restricted by consumers through Stackelberg game and price-based IDR. The second-stage dispatch is optimization of consumers and generation base. The proposed reward-based IDR gains the mutual benefit between the consumers and the generation base. The coalition game is used to gain equilibrium among consumers in the reward-based IDR, realizing the multi-player equilibrium and intraday optimization. Finally, simulation results verify advantages of the proposed strategy.
