IntroductionIn view of the inferior position of coal-fired units in the power market competition compared with other types of power generating units, this paper, based on the situation of Zhuhai Power Plant, explores the control strategies of the units themselves and the ways to reduce production costs from the modification of external equipment, so as to improve the performance and efficiency of the units and obtain greater economic benefits. Method Combining to the current development level of thermal power technology and market requirements, feasibility analysis was carried out in three aspects: coordinated control parameters optimization, installation of energy storage system and heating converted project, and their optimization methods and necessary conditions were listed.
Result According to the current practice results of these technologies in various power stations, it is concluded that the optimization of the above-mentioned methods according to the actual situation of the units can reduce the generation cost, significantly improve the unit performance and its competitiveness.
Conclusion The optimization strategy discussed in this paper can effectively improve the current predicament of coal-fired units. It can not only improve the safety and reliability of the units in operation,but also ensure that the units occupy a place in the fierce market competition. It has practical guiding significance for all coal-fired units.
