摘要: 光伏、风电等可再生能源接入电网引起系统调峰资源紧张,并进一步限制了其并网容量,研究系统低谷负荷时段负调峰能力具有重要意义。文章分析了光伏发电及风电出力的时间互补性对系统调峰的影响,提出了综合考虑风、光机组并网引起系统调峰需求增大的2种场景,以负荷低谷时段负调峰能力极限为目标建立风光储联合系统优化调度模型。以华北某省实际电网为例,验证了模型的有效性。结果显示,综合考虑风光储的联合调度将显著缓解系统调峰紧张压力,促进新能源消纳。

Abstract: Photovoltaic (PV) and wind power (WT) integration incur the deficiency of power regulation resource, which limits the renewable energy accommodation into power system. Research on negative peak-regulation capability at valley-load level has significant importance. In this paper, the effect of time complementary between PV and WT on peak regulation is analyzed, and two extreme scenarios of peak regulation demand increase which is caused by the renewable energy integration are introduced. A scheduling model of wind-PV-ES joint system is proposed which is aimed to maximize the negative peak-regulation capability during valley-load level. The effectiveness of the proposed model is verified by an actual provincial power system in North China. The result indicates that the joint operation of WT, PV and energy storage (ES) can significantly release the pressure on peak-regulation capacity requirement, and promote the integration of renewable energy generation.

Key words:  photovoltaic generation, wind power, energy storage, peak regulation, renewable energy accommodation
