| 摘要: |
| 研究了电力市场环境下电网公司购电费用最小和煤耗(排放)最小双目标下实时调度策略问题.根据当前电力市场运营规则及实时调度自身特点与要求,在不影响计算精度的前提下简化了模型的复杂度,将2种不同优化目标下的最优策略应用反比例分配原则并结合相应的权重系数统一到一个模型与算式中,再利用优化排队法将所需调整的功率偏差量分配到相应机组.通过IEEE 3机9节点系统进行了仿真计算,验证了该模型算法的实用性和有效性.该算法所需数据少,计算量小,适合在电力市场条件下,运行方式调整频繁时快速得到计及购电费用及煤耗(排放)双目标的实时调度功率分配方案. |

| Abstract: |
| The real-time dispatch strategy of electric power company in market environment is studied with two objectives:the minimum purchase cost and the least coal consumption (emission). Considering the opera-tional rules of power market and the characteristics of real-time dispatch,the optimum strategies for two objectives are integrated without compromising its accuracy into a single model by the inverse proportion principle combined with the weighted coefficients. The optimized sorting algorithm is used to assi... |
