A microgrid is a localized grouping of electricity sources and loads that normally operates connected to and synchronous with the traditional centralized electrical grid (macrogrid), but can disconnect and function autonomously as physical and/or economic conditions dictate.
This design provides a way to effectively integrate various sources of distributed generation (DG), especially Renewable Energy Sources (RES). It also provides a good solution for supplying power in case of an emergency by having the ability to change between islanded mode and grid-connected mode.
In a microgrid, energy storage is able to perform multiple functions, such as ensuring power quality, including frequency and voltage regulation, smoothing the output of renewable energy sources, providing backup power for the system and playing crucial role in cost optimization.
Microgrid energy storage includes all of electrical, pressure, gravitational, flywheel, and heat storage technologies.
Microgrid technologies are improving rapidly, which is allowing wider deployment and greater control capabilities in both 'island' and 'connected' modes.
These rapid changes will provide significant opportunities for knowledgeable pools of private capital to assist with the design, construction and operation of microgrids.
Microgrid technologies can play a significant role in remote communities and locations.
They will have a growing role in the design of solutions that will address the 'energy poverty' of indigenous communities.
Canadian Green Fund is working to provide unique funding solutions to accelerate the development of micro grid projects.
