Abstract: With the development of social industry, numerous carbon emissions have led to global warming and caused a huge negative impact on the environment. Carbon neutrality has been proposed to solve this problem; one of the primary issues in achieving carbon neutrality in integrated energy systems is to reduce carbon emissions. This paper utilizes distributed ground source heat pump heat storage systems in integrated energy systems to simultaneously improve the utilization efficiency of wind energy and solar energy for the first time. Moreover, the carbon capture and storage technology in integrated energy systems is considered to store excess CO2 in geological layer. Energy storage in integrated energy systems is applied to adjust the energy network balance. Finally, a balanced broad learning prediction model considering various heterogeneous data is established for load forecasting with 96.12% prediction accuracy. In four cases of the lower or higher wind and solar energy generation curves, carbon emissions are reduced to 82.02% of the original at least.
