发布时间：2019-05-24 02:29
【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。
[Abstract]:With the increase of the permeability of clean energy power generation, the phenomenon of abandoning wind and abandoning light is becoming more and more serious. This paper analyzes the microgrid operation architecture and its internal source load architecture, proposes a microgrid autonomy strategy for clean energy local absorption, considers the participation of controllable load, and establishes an electrothermal joint robust scheduling model. In the model, the idea of robust scheduling is used to model clean energy power generation and load uncertainty, and interruptible load measures are used to explore the response potential of controllable load. The simulation results show that the participation of controllable load improves the flexibility of microgrid operation, and the proposed autonomy strategy can effectively eliminate clean energy power generation and realize the economic operation of microgrid. With the addition of robust control, the scheduling results tend to be conservative, and the backup and cost are increased.
