This system preferentially uses regenerable energy to connect the power of photovoltaic power plant to solid heat storage electric boiler, to build a combined heat supply system of ultra-low temperature air source heat pump and sold heat storage electric boiler. Reasonable operation and control strategies were proposed to guarantee continuous and reliable heat supply. After analysis on the operation data, it was found that the combined heat supply system has effective and reliable operation in heating period, and indoor temperature could reach the design standard of ultra-low energy building. Its successful application on ultra-low energy building provided effective solutions for zero-carbon and clean heat supply to buildings in severe cold regions, satisfying the national requirements for energy conservation and emission reduction.
