Swedish microgrids and off-grid energy storage

What is a microgrid energy system?

Microgrids are small-scale energy systems with distributed energy resources, such as generators and storage systems, and controllable loads forming an electrical entity within defined electrical limits. These systems can be deployed in either low voltage or high voltage and can operate independently of the main grid if necessary .

What can a microgrid do?

The microgrid also provided demand response services under the EU’s Interflex program designed to test out three important applications for grid support including peer-to-peer energy trading to create a local energy trading market supported by centralized and decentralized balancing systems.

Can a microgrid save Sweden's Electricity?

Sweden experienced approximately 50 wildfires during the summer of 2018 due to record heat and drought conditions. As climate change accelerates, microgrids such as Simris offer a model of how to maintain reliable electricity without increasing reliance upon on-site fossil fuel generation.

Which features are preferred when deploying energy storage systems in microgrids?

As discussed in the earlier sections, some features are preferred when deploying energy storage systems in microgrids. These include energy density, power density, lifespan, safety, commercial availabil-ity, and financial/ technical feasibility. Lead-acid batteries have lower energy and power densities than other electro-chemical devices.
