电力市场环境下解决机组组合问题的研究

提出了一种解决电力市场环境下机组组合的新方法 ,考虑了包括网络安全约束在内的多种约束条件。这种方法首先将一个大系统按系统通常的运行方式分成一些小的子系统 ,满足联络线功率不过载的约束条件 ,并在这些小的子系统之间分配负荷 ;然后将各子系统的机组组合问题分为两层的规划问题 ,用动态规划法和分段线性规划算法分别解决这两个问题 ,并满足时间约束 ,机组出力上升、下降速度约束等各种约束条件。本算法经一个 8机系统的检验 ,说明本算法是非常有效的

A new method for unit connection in competitive environment

In this paper a new method was proposed for solving unit connection problem in the electric power market, considered multiple constrains included network security constrain. First,it divided a large scale system into some small scale subsystems according to general system operation mode, satisfying restricted transfers power limit in interconnect links, then scheduled generation between subsystems. Secondly, it independently solved unit connection problem for subsystems using dynamic programming and section linear programming. The algorithm was tested by eight machine system.
