The invention relates to a micro-grid energy scheduling method considering various flexible loads and electric vehicles, which is characterized by comprising the following steps of: firstly, proposing a'source-grid-load-storage 'micro-grid topological structure considering the electric vehicles and various flexible loads; then modeling adjustable resources in the micro-grid and introducing a peak-valley normal period re-division method; secondly, considering the division of peak-valley time segments, solving the lowest operation cost of the microgrid under different configurations, and obtaining the optimal microgrid configuration; finally, simulation verification shows that the proposed optimization scheme can effectively relieve the impact of centralized charging of the EV on an external power grid during the peak period of power utilization through the energy cross-space-time transfer characteristic of the flexible load and guidance of ordered charging of the electric vehicle, assists energy storage to complete peak clipping and valley filling, stabilizes the power of a tie line, and improves the power utilization efficiency of the electric vehicle. And meanwhile, the operation economy of the micro-grid is improved, and relatively high power utilization experience of a flexible load user is kept.
本发明是一种考虑多种柔性负荷和电动汽车的微电网能量调度方法,其特点是,首先提出考虑电动汽车和各种柔性负荷的“源‑网‑荷‑储”微网拓扑结构;然后对微电网中可调节资源进行建模并介绍峰谷平时段重新划分方法;其次,考虑到峰谷平时段的划分,求解不同配置下微网的最低运行成本,得到最优微网配置;最后通过仿真验证表明所提优化方案通过柔性负荷的能量跨时空转移特性和引导电动汽车有序充电,可有效缓解EV在用电高峰时段进行集中充电对外部电网造成的冲击,辅助储能完成削峰填谷,稳定了联络线功率,同时提高了微电网运行的经济性且保持了柔性负荷用户较高的用电体验。
