A distributed smart grid that can “heal” itself in the event of system components failing has energy storage and energy management software at its core, grid-scale system integrator Alfen has said.
The Dutch company has just launched Cellular Smart Grid Platform (CSGriP), which allows a range of distributed energy resources (DERs) to be integrated into one network. Alfen claims that in the event of a grid outage, the various modular blocks of resources that can be added to the platform are able to function “autonomously”, keeping power supplies running in unaffected portions of the grid setup.
Alfen, which in the past few months has begun work on the first grid-scale lithium-ion energy storage system to be commissioned in the Czech Republic and repeated a similar feat in Belgium, said CSGriP essentially separates the grid out into smaller “cells”.
In the event of failures that cause outages, the individual building blocks of the platform are able to restart generation sources connected to it and allow the generators’ output to continue being delivered to individual customers without disruption. Alfen claims that using the system could significantly reduce the “duration and size of central grid power outages”.
System deployed at Dutch centre for sustainability and innovation
One system using the CSGriP platform is already in use, at ACRRES (Application Centre for Renewable Resources) in Lelystad in the central Netherlands. The national centre for applied research in green and clean energy technologies has a 1,200 hectare test site.
At Lelystad, the Alfen CSGriP system is being trialled for its ability to integrate wind, solar and biogas energy and to then sell that power on to consumers. It uses a 0.5MW energy storage system and what Alfen calls a “complex algorithm used for local energy management”, both of which were delivered and designed by the Dutch company.
