基于AHSPSO算法的DG并网位置优化研究

Study on optimization of DG access position on voltage distribution network based on AHSPSO algorithm

为寻求不同接线模式下分布式电源接入位置对配网电压优化的规律性,以系统电压影响参数最小化为目标,以功率平衡、节点电压、支路容量为约束条件,采用自适应和声搜索与粒子群优化混合(AHSPSO)算法对不同接线模式下的DG并网位置进行优化,得出不同接线模式下的最优接入位置。利用IEEE—33节点配网模型进行仿真对比,分析不同接线模式下DG的并网位置对配网电压影响的规律。结果表明:只有正确合理地配置不同接线模式下DG并网位置,才能够更为有效地发挥电压的支撑作用。

For access to the location of the distributed power supply for the regularity of the distribution network voltage optimization under different connection mode,aiming to optimize the target of system voltage influence coefficient,use power balance,node voltage,branch capacity as constraints,and use AHSPSO algorithm for different connection mode of distributed power grid position to optimize the wiring mode different optimal access position. Using IEEE—33 node distribution network model for simulation comparison,analyze on influence regularity of DG grid position on distribution network voltage in different connection modes. The results show that only correctly and reasonably configurate DG access position in different connection mode can more effectively play a role of voltage support.
