Analysis of micro-grid integration with PV, energy storage and ground-source heat pump based on DeST simulation

In this paper, DeST (Designer's Simulation Toolkits) was applied to simulate the energy consumption of the solar heat storage micro-grid system in Shijiazhuang. Based on the mechanical loss, the heat loss, the utilization rate of the delay time, the energy consumption of the ground-source heat pump coupled with the PV array in the micro-grid system was reasonably calculated. In this case, the economic benefit will be greatly improved in the micro-grid area.
