多端柔性直流输电经济性问题研究

摘要

针对多端柔性直流输电的经济性，建立多端柔性直流输电经济模型，分别从拓扑结构及经济调度两方面对其进行分析，并给出问题的目标函数及约束条件，运用遗传算法进行了求解。以某多端柔性直流输电系统为例进行验证，结果表明基于加权斯坦纳树的多端柔性直流输电经济拓扑相比于点放射式拓扑，减少了大量的建设投资及运行费用。%For the economy of VSC-MTDC, the VSC-MTDC economic model was established. This paper analyzed this model from two aspects of topological structure and economic dispatch, giving the objective function and constraint condition of it to solve the problem by using genetic algorithms. Taking a VSC-MTDC system for example, the results demonstrate that based on weighting Steiner tree, VSC-MTDC economic topology, compared with point radial topology, has reduced large amount of construction investment and operation cost.
