考虑需求响应激励机制的园区综合能源系统博弈优化调度

Optimal dispatch of park integrated energy system considering demand response incentive mechanism

建设源荷协调、灵活互动的综合能源系统是构建新型电力系统的有效路径.在综合能源系统下,通过价格、补贴等激励手段合理调节用户侧需求响应机制可以促进综合能源系统的经济高效运行.为制定合理的需求响应激励机制,首先充分考虑源侧可再生能源出力和负荷侧多类能源需求的不确定性,提出随机场景生成策略;然后提出计及用户需求响应的综合能源系统博弈优化框架,分别以园区综合能源系统运营商和综合能源用户效益最大化为目标,建立双主体博弈优化调度模型,并提出快速高效的求解算法;最后,基于某实际园区综合能源系统开展多场景算例仿真分析,制定合理有效的需求响应价格激励方案.调度结果表明,所提出方案可以有效提升综合能源系统运行商和用户的效益.

Building an integrated energy system with coordinated source and load and flexible interaction is an effective way to build a new type of power system.Under the integrated energy system,reasonable adjustment of the user-side demand response mechanism through incentives such as electricity prices and subsidies can promote the economic and efficient operation of the integrated energy system.In order to formulate a reasonable demand response incentive mechanism,first,the paper fully considers the uncertainty of renewable energy output on the source side and multi-type energy demand on the load side,proposes a random scenario generation strategy,and then proposes a game optimization framework for an integrated energy system that takes into account user demand response.With the goal of maximizing user benefits,a dual-agent game optimal scheduling model is established,and a fast and efficient solution algorithm is proposed.Finally,a multi-scenario simulation analysis is carried out based on the integrated energy system of a real park,and a reasonable and effective demand response price incentive plan is formulated.The scheduling results show that the proposed plan can effectively improve the benefits of system operators and users.
