中文说明：基于粒子群算法的电力系统负荷分配问题（1）数学模型： 以IEEE 3机6节点为工况模型 ，Load=850MW （2）目标函数： minF=∑(i=1，Ng)Fi(PGi)，Fi(PGi) =aiPi2+biPi+ci+Ei，考虑阀点(Valve-Point)效应 （3）约束条件： a.发电机组输出功率上下限约束，即PGi min<=PGi<= PGimax； b.电力负荷平衡约束，忽略网损，即∑(i=1，Ng)（PGi）= PGD
English Description：
Based on the particle swarm optimization algorithm of power system load allocation problem (1) mathematical model: IEEE 3-machine 6-bus operating model, Load=850MW (2) objective function: minF= sigma (1 ng) fi (PGI), fi (PGI) =aiPi2+biPi+ci+Ei, consider valve point (Valve-Point) effect (3) constraint conditions: A. The generator output power and lower bounds, namely PGI min< =PGi< = PGimax; B. the load balance constraint, ignore network loss, namely sigma (1 ng) (PGI) = PGD
