摘要:建立了含分布式电源的基于多种负荷方式(最大、最小和一般负荷方式)配电网重构模型,取折算后的综合网损最小
的方案为最佳方案。对二进制粒子群算法(BPSO)按其适应值方差大小进行分类,对不同类别的粒子采取不同的进化策略和
不同的自适应动态惯性权重,加快粒子收敛的速度;并引入遗传算法的变异操作,克服了粒子群算法易早熟的缺点。仿真结
果表明,重构后系统的网损有较大降低,从而验证了所提算法的有效性。

Abstract: This paper builds a reconfiguration model of work with DG based on various load modes, and takes the
work loss plan to be the best option. Binary particle swarm optimization (BPSO) is classified according to
value of fitness variance, and different evolutionary strategies and adaptive dynamic inertia are adopted for different types of particles,
speeding up the particle convergence; the variation operating of ic algorithm is applied to avoid the precocity of PSO. The
simulation results show that work loss has been greatly reduced after work reconfiguration, verifying the effectiveness
of this algorithm.
