Energy storage system in Energy Society microgrid with solar production

An energy society is an operating environment formed by companies engaged in industrial and commercial activities. These companies can produce all the energy they need on their own, and customers can share resources. For example, the energy surplus produced can be used flexibly among other members of the community or sold on the electricity market. This kind of intelligent system can participate flexibly in different energy markets, and if necessary, the energy system will also be able to operate independently on the island by disconnecting from the national grid.

Merus^® Energy Storage System – part of a smart microgrid

A 1.6 MW / 1.3 MWh 20 kV Li-ion battery energy storage system provides a buffer for excess solar production for later use and enables a black start capability for gas generators. The energy storage can provide uninterrupted power supply during regional grid failure and guarantees uninterrupted electrical function to the Energy Society. The energy storage enhances the power quality and minimizes losses in different electrical components such as transformers, cables, etc. It also extends the lifetime of different electrical devices and components.

The energy storage is participating in the well-paid frequency reserve markets (FCR) and also bridges the gas generators to the markets.
