基于改进DPSO的含风力发电的配电网无功优化规划

研究了风力发电系统并网后配电网无功优化问题,将年负荷持续曲线处理为五种负荷运行方式,考虑风电机组输出功率的波动性,以年电能损失费用与无功补偿设备的投资费用之和最小为目标函数,以功率平衡、过补偿约束、电压合格、馈线电流约束为约束条件,应用改进的离散粒子群算法(PSO-GA)优化并联电容器组的安装位置和容量。仿真结果证明了该优化策略的有效性及经济性。

Improved DPSO Based Reactive Power Planning in Distribution Networks with Wind Power Generation

Reactive power optimization problem in distribution system with wind power system is analyzed in this paper.The load duration cure is approximated with five load levels,considering wind power volatility.In the objective function,the sum of power loses cost and new adding shunt capacitor devices investment divided in each year are considered,and power balance,over compensation,satisfaction voltage quality are the constraints conditions.The improved discrete particle swarm algorithm(PSO-GA) is adopted to optimize placement and sizing of shunt capacitors.The simulation results indicate that method proposed for the optimization problem is effective and economical.
