Optimal Unit Commitment with Transmission and Energy Constraints

9219151要素研究解决了全网络传输约束下的发电调度优化难题。如前所述，这个问题很棘手。这里采用的方法是将大问题分解为三个相关的子问题。一个是我们熟悉的最优潮流问题。另一种结合了最小运行时间和停机时间限制；这是一个相对简单的动态规划问题。第三个是二次规划问题，受制于“斜坡”和能量限制。这三个子问题的有效迭代求解需要开发专门定制的内点算法，并使用创新的新思想来调整增广拉格拉格惩罚参数。＊＊＊

9219151 Clements The research addresses the difficult problem of optimizing generation scheduling with full network transmission constraints. The problem is intractable as stated. The approach taken here is to decompose the large problem into three related subproblems. One is the familiar optimal power flow problem. Another incorporates minimum up-time and down-time constraints; it is a relatively simple dynamic programming problem. The third, a quadratic programming problem, is subject to "ramping" and energy constraints. Efficient iterative solution of these three subproblems requires the development of specially tailored interior point algorithms and the use of innovative new ideas for adjusting the augmented Lagragian penalty parameter. ***
