Photovoltaic thermal collector driven combined cooling, heating, and power systems are gaining traction as an alternative renewable energy-based solution for addressing the energy demands of buildings in residential settings. The performance of such systems could be enhanced with control strategies and the integration of multiple tanks. In this study, a numerical model of a residential-based photovoltaic thermal collector driven combined cooling, heating and power system controlled via a novel dual-tank latent heat thermal energy storage strategy, which allows the system to shift the thermal loads to different times of the day and simultaneously operate multiple tanks, is developed in TRNSYS and C++. The performance of the system operating under various modes is investigated via a case study that considers a three-bedroom home located in Ottawa, Canada. The phase change material melting temperature, load loop supply temperature, and latent heat thermal energy storage tank height are varied in the analysis resulting in 27 annual simulation scenarios. Within the simulation space considered, the annual solar and electricity fractions are shown to vary between 10.3 % and 39.7 %, and 23.2 % and 33.2 %, respectively. The greatest solar and electricity fractions occur at a supply temperature, phase change material melting temperature, and latent heat thermal energy storage tank height of 40.6°C, 38 °C, and 1.8 m, respectively. Results show that the system is more attractive when lower supply temperatures and larger storage tank volumes are selected and the novel control strategy might be an alternative to existing conventional methods.
