Energy storage systems

Residential storage systems store and release energy based on the current load consumption and local energy production. These systems can directly manage - or connected to - a load management system, which requires multiplel metering points. To avoid the system feeding the grid, a fast response time is essential, particularly at the main meter. In the near future, we expect grid-leve interconnection of these distributed energy buffers (initially in AC, and later directly in DC), requiring middleware solutions to coordinate an optimised use of the available stored energy.

Commercial storage systems store large amounts of energy by utilizing renewable resources or taking advantage of low energy prices, releasing it when demand is high and there is a risk of overloading the grid. These systems are used both in commercial and industrial parks, as well as by utility operators. Currently, energy transactions occur in AC, but the future will likely see the adoption of DC microgrids, where conversion inefficiencies are eliminated. The expected availability of DC power supply is driving the development of a new concept of industrial distribution systems, where DC is directly available within industrial facilities.​
