    摘要:

    考虑到户用负荷的多样性、丰富性及用电随机性带给户用多微网系统互联运行的极大挑战,对此提出一种基于事件驱动机制的自动需求响应策略。采用事件驱动机制,将户用微网的运行状况划分为不同的事件。根据事件驱动信号,结合价格激励与调度潜力引导负荷完成自身用电优化,以此实现自动需求响应。在此基础上,将能级概念引入能量共享模型中,通过对多微网系统中各个子微网的能级计算,决定微网间的交互功率,降低了网间与网内的耦合性,使得能量共享模型具有较低的复杂性。以某一户用多微网系统为例进行仿真分析,仿真结果表明所提算法能够有效降低户用多微网系统的运行成本,提高优化效率。

    Abstract:

    This paper proposes an automatic demand response strategy based on event-driven mechanism, considering the diversity and richness of residential loads and great challenges brought by random electricity consumption behaviors to residential multi-microgrid system. The operational statuses of residential microgrids are divided into different events by using event-driven mechanism. The residential load is guided to fulfil consumption optimization considering price incentive and schedulable potential with the event-driven signal, so as to achieve automatic demand response. On this basis, the concept of energy level is introduced to the energy sharing model. By calculating the energy levels of each sub-microgrid in multi-microgrid system, the interactive power among microgrids is determined. The decoupling between inter-network and intra-network can decrease the complexity of energy sharing strategy. The numerical simulation results of a residential multi-microgrid system show that the proposed algorithm can effectively reduce operating cost of residential multi-microgrid system and improve optimization efficiency.
