世界正面临着全球变暖和环境保护的挑战。另一方面，由于经济的增长和人口的增加，对电力的需求正在快速增长。由于需求的增长也是能源方程中的一个重要因素，因此仅靠可再生能源无法在短时间内产生足够的电力来填补缺口。因此，不能立即排除燃煤等化石燃料电厂的发电能力和后续负荷的灵活性。然而，任何新的燃煤电厂都应该比传统电厂更清洁。超临界电厂是改善环境和提高效率的最佳选择之一。然而，在英国是否采用这项技术一直存在一个问题，因为尚不清楚SC工厂的性能是否能够满足英国电网规范的要求。本文通过数学建模和电网规范符合性仿真，研究了SC电厂的动态响应。提出了一种基于广义预测控制替代配置的电厂控制新策略。
The world is facing the challenge of global warming and environment protection. On the other hand, the demand of electricity is growing fast due to economic growth and increase in population. Since the growth in demand is also a heavy factor in energy equations, then the renewable energy alone is not able to generate enough electricity to fill the gap within a short time of period. Therefore, fossil fuel such as coal fired power plants cannot be ruled out immediately due to their generation capacity and flexibility in load following. However, any new coal fired stations should be cleaner compared with traditional power plants. Supercritical power plants are one of the most suitable choices for environmental enhancement and higher efficiency. However, there has been an issue of whether or not to adopt this technology in the UK because it is not clear whether the performance for SC plants can satisfy the British Gird Code requirement. This thesis reports a study of dynamic responses of SC power plants through mathematical modeling, and simulation for Gird Code compliance. It also presents a new control strategy based on an alternative configuration of generalized predictive control for power plant control.
