In the case of deep peak shaving of thermal power units, it can absorb more photovoltaics and wind power, and also reduce the efficiency of thermal power plants and increase the environmental cost of society. This paper analyses the thermal power units under unconventional conditions from several influencing factors. The economics of operation, and innovative consideration of the current on-grid price and the latest government peaking subsidy factor. Firstly, according to the operating state and energy consumption characteristics of thermal power units, the peaking process is divided into conventional peaking, no oil depth adjustment and oil injection depth peaking, and the main factors affecting the deep peaking capacity of thermal power plants are analysed. The peaking energy cost model of thermal power units at different stages, and the actual power plant as the research object, the simulation results under different scheduling strategies are given. The results show that it is the most economical to increase the peaking depth of the unit to 54% of the rated capacity. The research results will provide a reference for better consumption of new energy.
