考虑分布式光伏不确定性的输配电系统供电能力评估
Evaluationof Power Supply Capacity of Integrated Transmission and Distribution Systems Considering Distributed Photovoltaic Uncertainty
摘要
Abstract
The calculation of power supply capacity of transmission sections is a basic task to ensure the safe operation of power systems.In recent years,in order to accelerate the realization of the dual carbon goals,distributed photovoltaics are massively connected to various distribution systems,and they are closely interconnected with the transmission system,becoming a huge integrated transmission and distribution systems.Therefore,when calculating the power supply capacity of each section in the transmission system,it is necessary to consider the uncertainty caused by a large number of photovoltaic power generation and reduce the calculation burden.Therefore,this paper proposes an evaluation method of power supply capacity of transmission and distribution system considering distributed photovoltaic uncertainty and establishes the calculation model of power supply capacity of the transmission and distribution system with distributed photovoltaic.Aiming at the characteristics of large scale and complex constraints of transmission and distribution systems,the paper also proposes a distributed algorithm based on analytical target cascading to realize decoupling and parallel solution of transmission and distribution systems.In addition,when solving the lower distribution system optimization sub-problem,it adopts the column and constraint generation algorithm to solve it.The proposed method not only considers the uncertainty of distributed photovoltaic,ensures the safe operation of distribution system,but also maintains the independence between transmission system and distribution system.关键词
