摘要:
      综合能源园区运行控制应兼顾多方市场主体利益诉求,针对不同类型园区供能差异化需求,提出计及用户诉求的日前调度与实时调度相结合的综合能源园区多时间尺度优化调度策略。首先,构建包含智能用电管理单元、电-气耦合联供单元、EV充电单元和用户电-冷用能调度单元的园区基本架构,并分析市场环境下园区运行方法;其次,在日前调度中建立以运营商利润和用户评价为目标的园区非合作博弈模型,确定园区能价和用能安排;再次,针对日前购电偏差问题,建立考虑不同类型用户用能诉求的含能量互保行为的实时能量偏差应对模型;最后,以14节点配电网和7节点天然气管网组成的微能源网为场景,对所提模型进行仿真验证,证明所提模型有效性。结果表明本文所提多时间尺度优化调度策略能够提升园区多方市场主体经济效益,以及兼顾考虑用户多样化用能需要的可行性。
Abstract:
      The operation control of the comprehensive energy parks should take into account the interests of multiple market subjects. According to the demand of energy supply of different types of parks, this paper proposed a multi-time scale optimization for MEP that combines day-ahead scheduling dispatch and real-time dispatch with user demands. Firstly, a MEP model including intelligent power management unit, power-gas combined supply unit, EV charging unit and user power-cold energy dispatching unit was established, and analyzed the operation methods of the park under the market environment. Secondly, the paper established a non-cooperative model with the goals of operator profit and user evaluation in day-ahead dispatch to determine energy prices and energy use arrangements of MEP. Thirdly, aiming at the problem of forecasting error in day-ahead dispatch, the energy deviation coping model which includes energy coping strategy and meets different types of users" energy demands was constructed in real-time dispatch. Finally, the paper simulated the proposed model with a 14-node distribution network and a 7-node natural gas pipeline network as the scene to verify the effectiveness of the proposed model. The result shows that the multi-time scale optimization strategy can improve the economic benefits of multi-market participants in the park, as well as the feasibility of taking into account the diversified energy needs of users.
