摘要: 随着大量的分布式电源及电动汽车集群接入配电网,负荷的种类呈现多元化的特点。分布式电源的随机性和波动性给配电网的规划带来了巨大挑战,为此,提出多元化负荷接入适应配电网的规划方法研究。首先,以线路允许接入的分布式电源容量最大为目标,建立配电网规划模型;然后通过在每个节点接入分布式电源生成海量允许接入的待选方案,使用粒子群优化算法对模型进行求解,生成分布式电源容量最优配置方案;最后分析分布式电源接入配电网后对配电网造成的影响。实际算例仿真结果验证了模型的有效性和合理性。

Abstract: With a large number of distributed power sources and electric vehicle clusters connected to the distribution network, the types of loads are diversified. Due to the randomness and volatility of distributed generation, it brings great challenges to the planning of distribution network. Therefore, the planning method of diversified load access to adapt to distribution network is proposed. Firstly, the distribution network planning model is established with the goal of maximizing the capacity of distributed generation allowed to access the line. Then, by accessing distributed power supply at each node, a large number of alternative schemes are generated.Finally, the particle swarm optimization algorithm is used to select the optimal access scheme for the generated massive access scheme to guide the planning of the distribution network. The simulation results of practical examples verify the validity and rationality of the model.

Key words: distribution network planning, capacity configuration, distributed power supply, particle swarm optimization algorithm
