摘要
研究分布式电源的接入容量对配网电压的影响有着重要竟义。针对DG接入容量对配网电压影响的问题,首先利用前推回代的潮流计算法计算出分布式电源接入辐射型配电网前后各节点的电压,建立了以电压变化率和系统电压影响参数为目标函数的优化模型,采用粒子群与和声搜索相结合的混合算法,分析了分布式电源的不同接入容量对配网电压的影响,得出不同接入容量对配电网电压影响的规律。利用节点配电网模型进行了仿真,结果表明,合理的接入容量能够更有效地维持电压稳定性。
Considering the access of distributed power supply capacity of the influence of the distribution network voltage has important unexpectedly righteousness.The DG access has an important influence on the capacity of distribution network voltage.Firstly,the author uses power generation power flow calculation method to calculate the distributed power access radiant distribution network before and after the voltage of each node.The objective function of optimization model established by voltage change rate and system voltage influence parameters.Adopting the combination of particle swarm and harmony search hybrid algorithm,analyses the different access of distributed power supply capacity of distribution network voltage distribution.It is concluded that different access capacity on the effect of power voltage.Using nodes distribution network model,the simulation experiment simulation results show that reasonable access capacity can more effectively to maintain voltage stability.
