Demand-side management-based optimization of all-season performance of a hybrid photovoltaic/thermal-linked system with a heat pump
The research develops a hybrid photovoltaic/thermal-linked system with a heat pump and thermal energy storage in a single building,combining it with the idea of demand-side management to solve the issue of excessive building energy consumption.To define its operational performance,a dynamic simulation model is created.After that,the configuration is optimized for demand-side management,and the cost and energy use of various configurations are examined.The findings demonstrate that,as compared to the coupled system without storage,the ratio of feed-in tariff to total generation for the heating and cooling seasons is improved by 23.96% and 7.07%,respectively.The demand for power rose sharply at night,rising by a total of 5.07% and 104.50%,and the system is capable of good power load management.The set point for the temperature of the water tank is 43℃for the heating season and 24℃for the cooling season,respectively.This configuration uses the least amount of energy overall among all optimized configurations,with a season-wide energy savings rate of 41.77%,which is 7.10% higher than the rate without the use of management strategies.Approximately 50.9% and 72.7% of the total electricity used during the heating and cooling seasons is used during the storage period.To further lower the energy consumption of systems with control techniques and energy-saving benefits,it is useful to research demand-side management configuration optimization.
