摘要/Abstract

摘要：

随着新能源在电力系统中的占比升高，电力系统的灵活调节需求也随之增加。系统中的灵活性资源能否满足调节需求成为新型电力系统建设过程中亟待解决的问题。基于形态学分解理论，建立了考虑储能特性的电力系统灵活调节能力充裕度分析模型；使用2种不同的运算子进行形态学分解，从电力系统净负荷曲线中分解得到了系统灵活调节能力充裕度分解结果；然后针对不同的灵活性调节需求，计算了不同装机容量灵活性资源系统的灵活调节能力充裕度；基于某省电力系统实际运行数据，验证了所提方法的有效性，计算了满足全部系统灵活调节能力充裕度的最小储能装机容量。

关键词: 数学形态学, 灵活调节能力充裕度, 调节价值

Abstract:

As the proportion of renewable energy in the power system increases, the demand for flexible regulation in the power system also increases. Whether the flexibility resources in the system can meet the regulation demand has become an urgent problem to be solved in the construction process of the new power system. Based on the theory of morphological decomposition, a model for analyzing the adequacy of flexible regulation capacity of the power system considering the characteristics of energy storage is established. Two different operators are used for morphological decomposition, and the results of the decomposition of the system's flexible regulation capacity adequacy are obtained from the net load curve of the power system. Then, for different flexible regulation demands, the flexible regulation capacity adequacy of flexible resource systems with different installed capacities is calculated. Based on the actual operating data of a provincial power system, the effectiveness of the proposed method is verified, and the minimum installed capacity of energy storage required to meet the adequacy of full system flexible regulation capacity is calculated.

Key words: mathematical morphology, the adequacy of flexible regulation capacity, regulation value
