Capacity optimization configuration of a solar-storage combined generation system for ground source heat pump heating
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.
