Research on the Impact of Coal Fired Power Unit Renovation on Thermal and Electric Load Characteristics

This article focuses on the implementation of the “triple transformation” policy for coal-fired power units, and studies the thermal and electrical load adjustment space of the “triple transformation” thermal power plant composed of condensing units, high-backpressure transformation, bypass heat supply transformation, and low-pressure cylinder 0 output transformation units. In multi energy complementary systems such as fire wind solar, the applicability of the “triple transformation” of coal-fired cogeneration units to different renewable energy penetration rates was analyzed, as well as the collaborative operation mechanism and multi scenario analysis of multiple types of power sources.
