摘要:直流配电系统具有可控性好、损耗低、电能质量高、输电容量大等特点，适宜于分布式电源的多点接入，是配电领域新的发展方向。经济调度是直流配电系统发展的关键技术之一。首先，在分析直流配网特性的基础上，建立基于日前计划和实时调度的直流配网多时间尺度经济调度模型，通过2个阶段的协调优化来实现直流配网的经济调度；然后，结合具体算例，利用改进粒子群算法对该模型进行求解；最后，优化结果验证了所提经济调度模型的正确性和有效性。
Abstract：DC distribution system is characterized by good controllability, low loss, high power quality and large transmission capacity. It is suitable for multipoint access of distributed generations, and it is the new development direction of distribution system. Economic dispatch is one of the key technologies for the development of DC distribution system. Based on the analysis of the characteristics of DC distribution network, a multi-time scales-based economic dispatch model is firstly established for DC distribution network, which is divided into two stages: day-ahead optimal scheduling and real-time scheduling. Through the coordination and optimization of two stages, the economic dispatch of DC distribution network is realized. Then, a specific example of the model is solved by the improved particle swarm optimization (IPSO) algorithm. Finally, the correctness and effectiveness of the proposed economic dispatch model has been verified through the optimization results.
