说明：  本程序用matlab编写，主要是为解决IEEE40节点电力负荷分配问题而想的一种算法。我把该算法命名为水桶法，是受一桶水的高度总与这个桶的最短一块木板齐平的原理，算法每次迭代把功率分配给需要最小消耗的机组上。
(This program with matlab, main is to solve the IEEE40 node power load distribution and think of an algorithm. I put the algorithm named bucket method, by a bucket of water is the height of the barrels of the shortest total and a board at the principle, each iteration algorithm the power allocation to the minimum consumption on the unit needs. )
