“…Battery energy storage plays a key role in supplying load power during peak hours when utility sourced electricity tariffs are higher in costs and there is no available PV to cover the demand [33]. Battery storage allows increased self-consumption by harvesting energy from solar panels during the day time and thus places less stress on the grid during the night time.…”

“…Battery storage can contribute substantially in reducing grid reliance [37][38][39][40] and allow users to shift peak demand easily for efficient use of electricity in low tariff periods, thereby utilizing demand side management [41,42]. Among the myriads of battery technologies, lithium-ion (Li-ion) has been demonstrated as the most applicable in the residential sector and preferred in microgrids because of its capability of deep-cycle operation, high specific energy, power density, and high number of charge discharge cycles [33,43]. Lithium-iron phosphate (LFP) is regarded as the safest among the Li-ion battery technologies [36] whilst also offering fast charge, as well as grid stabilization and a longer life cycle.…”

Shared Solar and Battery Storage Configuration Effectiveness for Reducing the Grid Reliance of Apartment Complexes

More than 2 million houses in Australia have installed solar photovoltaic (PV) systems; however, apartment buildings have adopted a low percentage of solar PV and battery storage installations. Given that grid usage reduction through PV and battery storage is a primary objective in most residential buildings, apartments have not yet fully benefited from installations of such systems. This research presents shared microgrid configurations for three apartment buildings with PV and battery storage and evaluates the reduction in grid electricity usage by analyzing self-sufficiency. The results reveal that the three studied sites at White Gum Valley achieved an overall self-sufficiency of more than 60%. Owing to the infancy of the shared solar and battery storage market for apartment complexes and lack of available data, this study fills the research gap by presenting preliminary quantitative findings from implementation in apartment buildings.
