System stability and efficiency through battery storage – a turning point of the sustainable transformation?
One of the challenges of dealing with renewable energy sources is the frequency and availability of supply. It has been demonstrated that the availability of renewable energy can directly be impacted by seasonal changes – in essence, less photovoltaic power is generated on average in winter months. How does battery storage help counter the seasonal energy deficits in a sustainable way? In this paper, we consider the stabilisation offered by batteries for the year-round availability of renewable power supplies.
