【摘要】 针对火电厂负荷优化分配,基于煤耗最小的单目标优化的局限性,提出了兼顾全厂煤耗最小和完成变负荷时间最短的双目标负荷优化分配模型,利用模糊理论将此双目标函数处理成相同约束条件下的单目标函数;然后用动态规划法求解,并将此结果同只考虑煤耗最小的单目标优化模型的结果相比较;最后对4台机组进行仿真。结果表明:采用多目标模糊优化设计对负荷优化分配效果良好。更多还原

【Abstract】 Aiming at the limitation of single-objective optimal model based on minimal Coal consumption of fossil-fired units in the load dispatch at present,multi-objective load optimal dispatch model considering both minimal Coal con- sumption and the shortest time to complete load is suggested.Fuzzy theory is adopted to change the multi-objective model to single-objective model,then solve it with dynamic programming algorithm and compare the result of single- objective model and multi-objective model,Finally,simulate the process.The result indicates:design of fuzzy multi- objective optimization is feasible and effective to load dispatch.更多还原
