摘　　要：无功优化是一个带有约束的多极值非线性组合优化问题,用传统的方法很难进行处理,且效果不佳。为此建立考虑电压稳定的以有功损耗最小为目标的电压控制数学模型,提出一种基于均匀设计和惰性变异的改进粒子群算法,并将该粒子群算法用于风-光互补发电系统的电压控制中。仿真试验显示:所建的电压控制数学模型既能保证电压质量,又能优化发电装置的无功出力,减少有功损耗;同时也显示了改进的粒子群算法比标准的粒子群算法有更好的优化效果。Optimization of reactive power is a non-linear combination optimization problem with constraints and multi-extremum. It is very difficult to handle by traditional methods. It was constructed a mathematical model considering voltage quality with the least active power loss as objective, proposed a new particle swarm optimization based on uniform design and inertia mutation （ UMPSO ）, which is used to control the voltage of the wind-photovoltaie hybrid power system. Simulation results venify the rightness of the built mathematical model. It makes voltage safe and decreases the loss of active power. The results also show that the advanced particle swarm optimization is more effective than the standard one.
