To improve energy utilization efficiency and reduce energy consumption

this study aims to increase the revenue generated by a solar-storage combined generation system for ground source heat pump heating.According to the segmentation of daily electricity demand into peak

flat

and valley periods

operational strategies for the solar-storage generation system are designed for both non-heating and heating seasons.Based on these operational strategies

an economically driven capacity optimization model was established

with photovoltaic (PV) panel capacity and storage battery capacity as decision variables.The effectiveness of the system capacity optimization model is validated through numerical simulations.The simulation results indicate that

without considering system costs

the system generates profits starting from the sixth year

with a total revenue of 242

418.58 yuan over ten years.With a system cost of 100

000 yuan

profits begin in the sixth year as well

yielding a total revenue of 166

329.55 yuan over the same period.This model effectively controls project costs and optimizes the generation system

maximizing system revenue while meeting heating season demands.
