Summary:Abstract Adding solar energy utilization equipment to an integrated energy system (IES) can improve the utilization rate of renewable energy and reduce the system cost. The optimal operation strategy of IES with photovoltaic and solar thermal utilization (PV-SH-IES) is investigated. The efficiency variation of CHP is considered, and the optimal results are compared and analyzed. The results show that: compared with IES, the operation cost of the PV-SH-IES is lower; it first falls and then rises with the increment of the photovoltaic area ratio, and the photovoltaic area ratio has an optimal value. The impact of photovoltaic equipment on the system cost is greater than that of solar thermal equipment.
