Use of battery storage
A quarter solution consists of a diverse mix of generators, consumers and energy storage systems. The task of battery storage is firstly to ensure a balance between generation and consumption within the quarter as well as a self-consumption-optimised power supply for the quarter. Secondly, battery storage can take over grid functions for the distribution grid in which the quarter is embedded.
Elements that a quarter solution can include are generation plants (photovoltaics, wind power, hydropower, etc.) and, on the consumer side, building infrastructure (lifts, lighting, building management, etc.), gastronomy (peak load), food retail (cold storage), data centres (UPS requirements), parking space management for electric mobility (charging stations) and the power supply for private households, among others. The sector coupling of heat and electricity results primarily from heat-led combined heat and power plants in the winter months, whose surplus electricity can be temporarily stored in batteries.
