Abstract
Air-source (air-to-air) heat pumps (ASHPs) provide an efficient electrification of space heating, but can increase electrical demand in homes, especially when replacing fossil fuel heating systems. While there is potential for solar photovoltaics (PV) and battery energy storage systems (BESSs) to meet ASHP system electrical demand in cold climates, it is not well documented in the literature. This paper aims at uncovering this potential in terms of grid flexibility using high temporal resolution (2.5-minute) simulations to better reflect electrical demand and component interactions. A detailed data-driven ASHP model is used to represent heat pump performance at different temperatures and compressor speeds, and key transient characteristics (i.e., cycling, defrost and start-up). Solar PV and BESSs, with an energy management control strategy (EMCS), showed notable potential to meet the electrical demand of ASHP systems during grid peak electrical demand hours, reducing the burden on the grid by 100% in many cases. Investigation across different Canadian cities, in different climates, demonstrated the necessity for region-suitable EMCSs to consistently satisfy ASHP system electrical demand during grid peak electrical demand hours and improve grid flexibility.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
