What Is a Microgrid?
A microgrid is a group of small-scale power grids with interconnected loads and distributed energy sources that operate independently or dependently of a larger utility grid to generate electricity for a localized area. Concerning the grid, a microgrid performs as a single controllable entity.
The microgrid can operate both in grid-connected and island mode by connecting or disconnecting itself from the grid. The advanced power grids are self-contained and have their power generation resources, such as renewable energy, energy storage systems, generators, etc., to generate electricity on their own. This improves reliability, resilience, and optimizes energy management.
The major components of a microgrid include electricity generation resources such as solar panels, wind turbines, natural gas or diesel generators, energy storage systems such as batteries, pumped hydro storage, thermal energy storage, etc., distribution infrastructure, point of common coupling (PCC), and a central control system.
Challenges Faced by Remote Microgrids
- The renewable energy sources, such as wind, solar, hydro power systems, etc., have their own characteristics and operational requirements. So, the integration of microgrids with renewable energy sources is a complex job.
- Due to a lack of technical support and spare parts, remote microgrids face various challenges in maintaining the grid. Equipment repair and maintenance become expensive and time-consuming.
- The high capital expenditure is another major challenge in developing a remote microgrid. The expensive renewable energy generation equipment, controller, storage systems, the transportation cost, labor charge, and installation expenses increase the overall budget of the project.
- The lack of clarity in regulations and policy is a challenge to proceeding with microgrid projects.
- Another major challenge is a lack of consumer awareness about the microgrid and its operation.
