Increasing residential air-conditioning demand and the growing number of solar photovoltaic (PV) systems installed in the residential sector have increased electrical net energy demand fluctuation. These severe fluctuations lead to a need for flexible generation capacities that can rapidly meet the fluctuating demands. To combat these fluctuations, utility companies have introduced different price plans to financially incentivize customers to reduce their demand during certain hours of the day, making residential electricity demand constant (or “flat”) for the daytime hours. This paper explores the feasibility of coupling precooling with PV to achieve “flat” residential net demand in three Phoenix, Arizona homes.
