| 摘 要： | 合理制定购电计划有利于减少购电支出和降低网损,提出了一种兼顾网损的购电计划数学模型,以全网日购电费用和网损费用之和最小为目标函数,并满足各种机组技术约束和系统安全约束,进一步解耦成依次单时段模型,降低了解空间维数,提高了寻优效率.采用灾变遗传算法进行求解,仿真结果表明,相比传统购电计划,所提模型在显著节约购电成本的同时很好地降低了网损,符合当前阶段电网公司经济调度的需求.

| Abstract: | Rational power purchase planning is helpful to decrease the power purchase costs and reduce the active power losses.A mathematical model of daily power purchase planning considering the active power losses is therefore presented in this paper,whose objective is to minimize the total daily costs of power purchase and that of active power losses of the whole networks,while satisfying all technical and security constraints.The model is decoupled to sequential single-interval model afterwards,so that the dimens... |
