摘要: |
区域综合能源系统(Regional Integrated Energy System, RIES)通常经电气接口与主动配电网(Active Distribution Network, ADN)相连,参与ADN需求响应调度。为了提高RIES与ADN的交互效益,提出了含多RIES的ADN双层博弈优化调度策略。在RIES内部,以RIES效益最大为目标,建立满足电-气-热负荷需求、响应ADN需求调度的RIES异质能优化协调调度策略。在此基础上,建立ADN与多RIES联盟的双层博弈调度模型。上层为ADN与RIES联盟的非合作博弈,ADN通过制定分时购售电价引导RIES联盟制定购售电策略。下层为RIES联盟成员合作博弈,达到联盟出力在成员之间的最优分配,并基于Shapley值对联盟成员分摊合作利益。采用粒子群算法求解博弈模型的纳什均衡点,得到最优电价策略及各RIES的最优购售电策略。算例结果表明,所提策略能够提高ADN削峰填谷能力,保障RIES的经济性及ADN的可靠运行。 |

Abstract: |
A regional integrated energy system (RIES) is usually connected with an active distribution network (ADN) through an electrical interface, and participates in the ADN demand response dispatch. To improve the interaction efficiency of RIES and ADN, a two-level game optimal scheduling strategy for ADN with multiple RIES is proposed. In RIES, a heterogeneous energy optimization and coordination scheduling strategy is established to meet the demands of electricity-gas-heat load of the RIES, and to respond to ADN electricity demand scheduling with the goal of maximizing RIES benefit. A two-layer game scheduling model of ADN and RIES-coalition is established. The upper layer is the non-cooperative game between ADN and RIES-coalition, and the ADN guides RIES-coalition to formulate power purchase and sale strategies responding to the ADN demand scheduling through a time-of-use purchase and sale price policy. The lower layer is RIES-coalition members’ cooperative game to achieve the optimal distribution of coalition trading power among members, and cooperation benefits are shared among coalition members based on the Shapley value. The particle swarm optimization algorithm is used to solve the Nash equilibrium point of the game model, and the optimal electricity price strategy and the optimal electricity purchase and sale strategy of each RIES are obtained. The results of a numerical example show that the proposed strategy can improve the peak shifting and valley filling capacity of ADN, ensure the economy of RIES and the reliable operation of the ADN.
