The cogeneration unit operates in a mode of 'fixing the power by heat', and the peak regulation capacity is only about 10%. The peak shaving difficulty has become the most prominent problem in the operation of the power grid. At present, the flexible peak regulation and reconstruction of domestic thermal power aims at a heat supply unit in winter, and how to regulate the peak in summer is a difficult problem in the presence of a plurality of thermal power plants. In order to meet the peak regulation requirement of a power grid and the survival requirement of a power plant in intense competition, deep peak regulation especially in non-heating seasons is imperative all the year.
