“…Xue et al [24] designed a DES combining carbon capture and solar technologies, and discussed the effects of three CO 2 utilization methods on the DES performance. Deng et al [25] constructed a DES jointly driven using a ground-source heat pump (GSHP) and solar energy, and further enhanced the overall performance of the coupled system by optimizing the GSHP starting factor. Ashrafi et al [26] investigated a hybrid DES system configured with GSHP and PV and demonstrated that the combination of the two renewable energy technologies is superior to DES coupled with GSHP or solar alone.…”

The use of distributed energy systems (DES) can utilize local resources to achieve flexible and efficient energy production and supply. However, this aspect of pollutant emission reduction has not been sufficiently investigated in current related studies. On this basis, this study establishes a DES system that integrates a ground-source heat pump, a gas turbine, a photovoltaic device and an energy storage device. An Improved Zebra Optimization Algorithm (IZOA) is proposed for optimizing the capacity of DES devices and the energy supply ratio of the ground-source heat pump. Using the economic cost saving rate (ECSR), pollutant emission reduction rate (PERR) and energy saving rate (ESR) as the optimization objectives, the study builds a DES configuration optimization model. By analyzing the arithmetic example of a large hotel building, the study verifies the effectiveness of the IZOA algorithm in solving the DES configuration optimization problem. This study provides useful research ideas in promoting the development of distributed energy systems, environmental protection and energy conservation.
