Model-Based Prediction Control for Photovoltaic/Thermal-Assisted Heat Pump Water Heating System

Abstract:

This paper presents self-sufficiency design for a photovoltaic/thermal assisted heat pump water heating (PVTA/HPWH) system by model-based prediction control methodology. Considering the effect of weather conditions on PVT characteristics, the reciprocal energy exchange of PVT evaporator and HPWH system could be well described by the proposed PVTA/HPWH model with better precision. Having the accurate model building, the power consumption of HPWH is self-sufficiently provided by PV electricity using a model-based prediction control methodology. Performance is evaluated through experimental measurement with a test rig of integrated PVTA/HPWH system of rated power 1 kWp under real climate conditions. The dynamic behaviors and performance analysis of the PVTA/HPWH system are conducted by theoretical and experimental analysis. The results have demonstrated the power autarky of the proposed PVTA/HPWH system with better performance.
