摘要:

新能源接入电力系统后,需要常规电源帮助平衡其随机性、波动性,故而产生了平衡成本。进行平衡成本的解析与计算,对促进新能源与常规电源利益的合理分配具有重要意义。将系统平衡成本分解为新能源消纳引发的新增备用成本、二次调频(SFR)成本及新增电能量成本。基于“等电量-顺负荷”方法,构建新能源相对负荷无波动性且无须为其预留备用、二次调频容量的虚拟场景,给出了基于场景模拟比较法的系统平衡成本计算方法。对修正的IEEE 39节点系统的平衡成本测算分析结果验证了所提方法的合理性。

Abstract:

After the integration of renewable energy into the power system, conventional power sources are needed to help balance its randomness and variation, which results in the balancing costs. It is of great significance to analyze and calculate the balancing costs to promote the rational allocation of returns between renewable energy and conventional power sources. The system balancing costs are decomposed into the incremental reserve costs, the secondary frequency regulation (SFR) costs and the incremental electricity energy costs caused by the renewable energy accommodation. Based on the “load-following transform”method, a virtual scenario of renewable energy with no fluctuation relative to load and no need to provide reserve and SFR capacity is constructed, and a calculation method for the system balancing cost based on scenario simulation and comparison method is given. The calculation and analysis results of the balancing cost of the modified IEEE 39-bus system verify the rationality of the proposed method.
