考虑居民热负荷主动需求响应的园区综合能源系统分布式优化运行方法

Active demand response (ADR) can not only reduce the operating and investment costs of integrated energy systems, but also apply its flexibility to more absorb clean intermittent renewable energies and reduce carbon emissions. In order to explore deeply the flexible ADR resources contained in the dynamic characteristics of residential heat loads and consider the residential privacy protection, this paper proposes a park-level integrated energy system optimal operation method for multi-users through fine residential heat loads ADR modeling. Firstly, the refined state space modeling of ADR resources of residential heat loads is carried out; Secondly, on this basis, the operation optimization model of a park-level integrated energy system considering ADR of residential heat loads is established; Thirdly, considering the users’ privacy protection, an algorithm based on alternating direction method of multipliers is proposed to decouple the overall large-scale optimization problem into both supply-side and demand-side subproblems to achieve distributed precise solution; Finally, a typical park-level integrated energy system with 128 residential users is analyzed to verify the effectiveness of the proposed method.
