文摘

Optimal control of a wind–PV-hybrid powered heat pump water heater is modelled. Daily energy cost saving of around 70.74% is shown. Saved energy is due to proposed optima control intervention with time-of-use. Potential of a daily energy saving of about up to 51.23% is shown. The optimal photovoltaic and wind energy feed-into the grid is modelled.
