Transient Stability Assessment of Power System Based on Spatial and Temporal Feature of Branch Potential Energy

摘要:

结合支路势能和近似熵理论，提出了基于支路能量时空特征的暂态稳定分析方法。通过《国家大气污染防治行动计划》规定的跨区输电线路电价政策、定价方法等内容的综合分析，提出了特高压直流分层接入方式下输电价格制定需考虑的因素。

Abstract:

In combination with the branch potential energy and approximate entropy theory, a transient stability analysis method based on the energy space-time characteristics of the branch is proposed. Through the comprehensive analysis of the cross regional transmission line price policy, pricing method and other contents specified in the National Action Plan for Air Pollution Prevention and Control, the factors that need to be considered in the setting of transmission prices under the layered access mode of UHVDC are put forward.
