摘要: 随着中国可再生能源基地建设的快速推进,由于传输容量限制、调峰能力不足、备用不足等原因引起的弃风、弃光问题日益严峻。针对可再生能源的消纳问题,分析了负荷侧的高载能企业的调控特性,结合高载能企业的经营现状,分析得出高载能企业具备参与电网调节、增加可再生能源消纳的能力,提出了考虑高载能企业的“荷-网-源”协调控制的思路,建立了考虑高载能企业隐私的分布式调度的闭环协调求解模型,并通过算例初步展示了“荷-网-源”协调的效益。

Abstract: With the fast construction of the renewable energy plants, the curtailment of wind and light power generation becomes increasingly frequent due to the limits of transmission, peak-load regulation and reserve capacity. To improve the integration of renewable energy, this paper focuses on the scheduling of energy-intensive enterprises (EIE). The properties of EIE model in load-side and the current operational status of EIE have been analyzed. Then the possibility that EIE participate in scheduling to improve the renewable energy integration is discussed. Based on the analysis, the paper proposes the idea and framework of “Load-Grid-Source” coordination. A modified decomposed coordinative scheduling (DCS) method is applied to solve the optimization problem. A case study is carried out by applying the method to prove the feasibility and efficiency of the method.

Key words: power grid, renewable energy integration, energy-intensive enterprises, “Load-Grid-Source”, coordination, decomposed coordinative scheduling
