摘　　要：随着清洁能源发电渗透率的提高,弃风弃光现象日趋严重。对微网运行架构及其内部源荷架构进行分析,针对清洁能源就地消纳提出微网自治策略,考虑可控负荷的参与,并建立了电热联合鲁棒调度模型。在模型中,利用鲁棒调度的思想对清洁能源发电及负荷不确定性进行建模,并利用可中断负荷措施对可控负荷的响应潜力进行发掘。仿真结果表明,可控负荷的参与提高了微网运行的灵活性,所提自治策略可有效消纳清洁能源发电,实现微网经济运行。加入鲁棒性控制后,系统调度结果趋于保守,备用和成本增加。With increasing penetration of renewable energy resources（RER）, renewable energy abandonment becomes more and more serious. Autonomy strategy for microgrid was proposed aiming at RER local consumption based on microgrid operation framework analysis and its internal power and load structures. A model of combined heat and power robust dispatch was constructed with controllable load（CL） participation taken into consideration. Robust dispatch theory was used when RER and loads were modeled and load interruption measures were used to explore CL interaction potential. According to case study results, microgrid operation flexibility was improved by controllable load participation, and RER could be efficiently accommodated through application of the proposed strategy and economic operation of microgrid was achieved. Dispatch results tend to be more conservative with robust control added and reserve capacity and cost is increased.
