摘要:

提出了一种基于模型预测控制(MPC)原理的大型风电场与燃气-蒸汽联合循环机组的滚动调度策略。该方法在考虑联合循环机组运行约束条件下，以等效电厂的经济最优为目标。首先介绍了燃气-蒸汽联合循环机组的结构和工作原理，以及风燃协调等效电厂的概念。然后根据联合循环机组的运行状态及起停过程建立了数学模型，并在该数学模型的基础上，同时考虑风电场弃风，以风燃协调等效电厂的整体经济性最佳为目标，提出一种基于模型预测控制的新型风燃协调滚动调度运行策略。仿真结果表明新方法使得等效电厂在跟踪调度曲线的基础上，实现风燃协调等效电厂的经济最优控制。

Abstract:

A rolling dispatch strategy of the wind farm and gas-steam combined cycle power plant (CCPP) coordinated system based on model predictive control (MPC) method is proposed. Considering the constraints of CCPP, this strategy aims to optimize the power generation in the coordinated system. Firstly, the structure and working principle of CCPP and the concept of wind-gas coordinated equivalent power plant (WGPP) are introduced. Secondly, considering the working state, start-up and shut-down process of CCPP, a mathematical model of CCPP is established. Based on this model and considering the wind power curtailment, a MPC-based rolling dispatch strategy of wind-gas coordinated system is proposed in order to maximize the benefit of WGPP. Finally, the simulation results demonstrate that the new strategy can not only make WGPP track the dispatch targets, but also optimize the power generation in WGPP.

Key words: wind power generation gas-steam combined cycle power plant model predictive control
