摘　　要：以高比例可再生电源为主的微网接入电力系统,在有效降低系统碳排放水平的同时,给系统带来大量不确定性因素。建立典型的“风-光-柴-储”微网结构,以经济最优、电能质量最优、碳排放最少、用户满意度最优为目标,总结了当前风、光等分布式微网电源对接入电网的主要影响。在此基础上,分别从确定模型、隶属度模型、区间数据模型3个方面总结了不确定参数建模方法,归纳了目前对含风、光不确定性电源微网优化调度的求解方法及各种方法的优缺点。最后,展望了含风、光不确定性电源微网优化调度的发展方向,旨在为微网不确定性优化调度研究提供参考。Connecting distributed microgrids characterized by high-proportion renewable energy to the grid system can effectively reduce the carbon emissions from the whole system,but seriously impact the stable operation for the system as well.A wind-solar-power-battery integrated system is constructed in pursuit of the optimal economy,highest quality of power,lowest carbon emissions and highest level of customer satisfaction.The negative effects of grid-connection of distributed sources,such as wind power and solar power,on the operation of power grid are summarized.Then,the uncertain parametric model for the microgrid is constructed using probabilistic model,fuzzy affiliation model,robust uncertainty set and interval-censored data set as reference.Different solutions for the optimization scheduling plans for the microgrid considering the uncertainties of renewable energy are proposed and compared.Finally,the development outlook of the power sources with uncertainties is proposed to guide the optimization scheduling of the distributed microgrids.
