摘要

In order to research the optimization allocation of Distributed Generation in distribution network with the static voltage stability index considered. The platform of Distribution Network of IEEE 33 nodes and Matlab simulation software based on the Distributed Generation in a total capacity of maximum as the objective function, the static voltage stability index L as the constraint conditions, using the adaptive particle swarm optimization algorithm of DG in Distribution Network location and sizing optimization. The conclusions obtained from the test system satisfy the static voltage stability index and the Maximum capacity of DG, which may be available for distributed generation connecting and planning in distribution networks.%为了研究在考虑静态电压稳定性情况下，配网中分布式电源的优化布置问题。基于IEEE 33节点配电网络和Matlab仿真测试软件平台，以分布式电源（Distributed Generation，DG）接入总容量最大为目标函数，以静态电压稳定指标L（Voltage Stability Index）为约束条件，应用自适应粒子群算法（Adaptive Mutation Particle Swarm Optimization Algorithm，AMPSO）对配电网络中DG的选址和定容进行优化。优化结果得出了配电网络中最优的DG布置方案，同时满足了配电网络电压稳定和分布式电源容量最大的要求，该研究对配网中分布式电源的规划提供了积极的指导意义。
