Abstract:

With the energy structure adjustment and power market development in China, cogeneration industry is undergoing a reform and an updating. As emerging technologies in this industry, advanced heat-supply technology and intelligent power generation can promote the energy transition in China. The principles of heat-electricity decoupling,multiple heat sources and digital twin, and their applications in cogeneration are introduced, and their technical potential in facilitating coal-fired units' performance are evaluated. Finally, it is pointed out that these two technologies can realize the optimal control on frequent boundary disturbances of thermal power units by improving units' operational flexibility. The technologies provide technical support for CHP, thermal power generation facilities, electric equipment and power grid, as well as accelerate the transformation of energy structure to a low-carbon and clean one.

Key words: CHP, heat-electricity decoupling, advanced heating, intelligent power generation, heating by multiple sources, digital twin, waste heat recovery, heating with large temperature difference, long-distance heating
