由于在世界各地的电力系统中存在和建设了大量的联合循环电厂，因此在解决机组组合问题时，越来越需要有一个更准确和实用的模型来代表这些类型的电厂。一种常用的优化技术来解决机组组合问题是对偶规划。本文主要研究在对偶优化框架下，利用动态规划求解联合循环电厂调度子问题。用于表示联合循环电厂的模型是基于组件的，这种新的联合循环电厂建模方式考虑了配置之间的可行过渡等约束，以及联合循环电厂必须保持在某个配置上的最小和最大时间。本文提出的模型的优点是，它准确地模拟所有的物理约束的联合循环电厂。此外，本文提出了混合联合循环电厂的建模，这些都是使用辅助锅炉，以增加蒸汽涡轮机所使用的蒸汽的生产。
Due to the existence and building of an important number of combined cycle plants throughout electric power systems around the world, there exists the growing need to have a more accurate and practical model to represent these type of power plants when solving the unit commitment problem. A commonly used optimization technique implemented to solve the unit commitment problem is dual programming. This work focuses on solving the sub-problem of scheduling a combined cycle plant using dynamic programming under a dual optimization framework. The model used to represent the combined cycle plants is component based; this new way of modeling combined cycle plants takes into account such constraints as the feasible transitions between configurations, and the minimum and maximum time that a combined cycle plant must remain on a certain configuration. The advantage of the model presented in this paper is that it accurately models all the physical constraints of combined cycle plants. Also, this paper presents the modeling of Hybrid Combined Cycle Plants; these are the ones that use an auxiliary boiler in order to increase the production of steam used by the steam turbine.
