PV/T heat pump system significantly suppresses temperature fluctuations, enhancing stability and performance.
Dynamic model simulations indicate a 46.7% improvement in temperature fluctuation suppression with a tank volume of 2 m3.
Load fluctuations present risks, with a hot water temperature decline of 7.6 °C during load reduction, highlighting system vulnerabilities.
Predictive compressor control is necessary to manage the 100 s thermal and 50 s electrical stabilization time lags identified.
