Technical scheme analysis of a district energy system

 Points out that district energy sources cover gas distribution, ground-source heat pump, energy storage and “multi-energy coordination”. Prioritizes the district energy sources according to the costs of various energy supply forms at different times under different load conditions. Presents the operation strategy of “intelligent coupling” after considering the heat balance of the ground-source heat pumps and energy storage. Compares and analyses the comprehensive calculation of investment, operation cost and income, suggests a “multi-energy coordination” scheme with market competitiveness.
