Summary:Abstract The existing regional integrated energy system with thermal storage electric boiler as the main body cannot solve the cooling problem. In this paper, LiBr refrigerators were added on its basis to realize an energy supply mode that integrates heating and cooling. Established a multi-party win-win mechanism to ensure the minimum risk and obtain the maximum benefit. The results shown that the power grid load reduction ratios in winter and summer were 39% and 31%, respectively. When the subsidy price was 0.1CNY/kWh, the spending gap between sensitive and insensitive users reached 40%. A case of 100 office buildings in Beijing shown that the optimal capacity of phase change heat storage was 80MWh.
