Study on Capacity Setting Technique of Flexible DC Interconnection System in Multi-distribution Station
摘要
Abstract
The converter station capacity is directly related to the reliability and economy of the flexible direct current(DC)interconnection system.In order to solve the capacity allocation problem of converter station after multi-distribution area is interconnected by flexible DC technology,a two-layer optimization model established to optimize the constant capacity of converter station.Taking the most benefits of the flexible DC interconnection system and the highest consumption of renewable energy as optimization object,the inner optimization model optimizes the power exchange scheduling strategy of the distribution system to obtain the optimal strategy of power exchange.Optimal mutual power support strategy given by inner model and constrain conditions such as reliability as well as economy are considered in outer model,so that optimal capacity-load ratio and the optimal capacity configuration of converter station can be obtained.The intelligent algorithm,such as particle swarm optimization algorithm,is used to solve the optimization model iteratively.Taking a three-terminal flexible and direct interconnection system as an example,the results prove the effectiveness of the method proposed in this paper.关键词
