摘要

With the rapid growth of electricity load, distributed generation has become the hot spot in power systems. In order to better fulfill their economic effects, firstly distributed power grid and then analyzes the impact on traditional distribution network of research . On this basis, and establishes the power of the optimal allocation model establishes the nodal voltage offset, system loss of minimum and max mum grid voltage stability of multi-objective optimization model and adaptive chaotic Particle Swarm Optimization algorithm for solving. Finally, analysis of examples verify the accuracy of the actual effects of the mode land its solution algorithm.%随着用电负荷的急剧增长，分布式发电成为了当今电力系统的研究热点。为了更好地发挥分布式电源的经济效应，本文首先对分布式电源接入电网后对传统配电网的影响作了分析研究。在此基础上，建立了电源的优化配置模型，确立了以减少节点电压偏移量、降低系统损耗量和提高并网电压稳定度的多目标函数优化模型，并利用自适应混沌粒子群算法进行函数求解。最后通过算例分析，验证了模型的实际效果和求解算法的准确性。
