Research on Modeling and Simulation Analysis of Hybrid Electric-heat Complementary Heating System

With the continuous development of the social economy and the advancement of the urbanization process, the application scale of the district heating mode based on cogeneration and district boiler rooms is expanding in northern China. Facing the carbon peak and carbon neutrality strategy, how to realize the carbon reduction of the central heating system still needs in-depth research. With the advancement of the construction of a new power system under the large-scale integration of renewable energy, the gradual implementation of electric energy substitution is of great significance for the low-carbon transformation of the heating industry. This paper proposes a new hybrid electric-heat complementary heating mode. We establish the simulation model of the hybrid electric-heat complementary heating system and analyze the configuration scheme of the electric heating equipment in combination with the specific case. The hybrid electric-heat complementary heating mode can further improve the system performance compared with the centralized electric-heat complementary heating mode. The higher the proportion of electricity replacing the heating load, the more noticeable this optimization effect is.
