摘要
机组组合是水电站短期发电计划中一个重要的问题,合理的组合运行能带来显著的经济效益。采用进制数编码形式表示机组的运行状态,以给定的负荷为基础,对机组运行进行优化,存储运行状态少,且最优方案不受初始值的影响;采用M atlab语言编写了电站内全局的最优机组组合及机组间负荷的合理分配程序,并给出了计算程序。实例计算结果表明:利用进制数的优化算法在机组组合优化问题上是可行的,也是有效的,该算法的收敛性好且速度快,对多机组电站的经济运行具有较好的实用价值。
Unit commitment is a very important issue of short-term power generation schedule in hydropower station and reasonable unit commitment operation can bring about significant economic benefits.The numeration system code is used to indicate the operation state of the unit and the unit commitment operation is optimized based on a given load,resulting in less storage of operation state and without influence of initial value on optimal scheme;the programs of global optimal unit combinations and the rational allocation of unit load are compiled by Matlab language;and the calculation code is given as well.The calculation results show that the optimization algorithms based on numeration system are feasible and effective with good convergence and high calculation speed,which are of practical significance for the economic operation of multi-unit hydropower station.
