Peak-regulation refers to the planned regulation of generation to follow the load variation pattern either in peak load or valley load periods. Sufficient peak-regulation capability is necessary for the reliable and secure operation of power grid, especially in urban regions with extremely large peak–valley load difference (Jin et al., 2020).

The EMS is composed of intelligent software and hardware that work together to manage energy storage and distribution. It constantly monitors energy production and consumption rates, making real-time decisions about when to store energy and when to release it. This ensures a consistent energy supply, even when production rates vary.

As of 2024, the price range for residential BESS is typically between R9,500 and R19,000 per kilowatt-hour (kWh). However, the cost per kWh can be more economical for larger installations, benefitting from the economies of scale. Anticipated advancements in technology and scaling up of productions will likely drive down these costs in the future.

The systems — also called ‘community batteries’ or ‘community energy storage systems’ 1, 2 — help to increase the self-consumption of renewable energy in a neighbourhood by bridging gaps in electricity generation and demand. Algorithms play a critical role in the functioning of these systems by controlling the batteries’ (dis)charging processes.

The slope of the loading curve, analogous to Young's modulus in a tensile testing experiment, is called the storage modulus, E '. The storage modulus is a measure of how much energy must be put into the sample in order to distort it. The difference between the loading and unloading curves is called the loss modulus, E ".
