【摘要】：多个微电网互联组成智能配电网,能够提高清洁能源的利用率,减小源荷波动带来的负面影响。但多个微网间的调度问题具有非合作特性,难以直接通过集中优化求解。鉴于此,设计了基于多代理系统的智能配电网动态博弈框架。首先根据电能的用途与归属,建立了基于价格差异与时间贯序权重的智能配电网两阶段快速调度决策模型。然后,在考虑清洁能源随机性的基础上,建立了基于最大投标风险承受比例的电量决策模型和基于最小用电成本的电价投标决策模型。最后,开发了基于多代理系统的动态博弈仿真平台并加入上述调度、博弈模型,对比分析了多种策略下的仿真结果,证明了所提快速调度和动态博弈模型的有效性。
[Abstract]:Multiple microgrid interconnected smart distribution networks can improve the utilization of clean energy and reduce the negative impact of source load fluctuations. However, the scheduling problems among multiple micronetworks are non-cooperative and difficult to solve directly through centralized optimization. In view of this, a dynamic game framework of smart distribution network based on multi-agent system is designed. Firstly, according to the usage and attribution of electric energy, a two-stage fast dispatching decision model of smart distribution network based on price difference and time sequential weight is established. Then, on the basis of considering the randomness of clean energy, the electricity quantity decision model based on the maximum bidding risk tolerance ratio and the electricity price bidding decision model based on the minimum power cost are established. Finally, the dynamic game simulation platform based on multi-agent system is developed and the above scheduling and game models are added. The simulation results under various strategies are compared and analyzed, and the effectiveness of the proposed fast scheduling and dynamic game model is proved.
