Learn MoreThe control system for the smaller microgrid will likely cost less in real dollars but consume more of the overall project budget than the control system for the larger one. “Your control system may be a little less in smaller ones, but it's going to be a much larger portion of the cost than in the larger one.
Combining on-site generation, battery energy storage and intelligent energy control software can transform a site or area into a smart microgrid. These self-contained electrical grids can operate connected to, or independent of, the wider power grid.
True, larger microgrids will likely be more expensive than smaller microgrids — but in gross terms, not necessarily on a per kilowatt basis. In fact, generation for a very small microgrid tends to cost more per kilowatt than a comparable larger version. For example, a 50-kW solar array is more expensive per kilowatt than 1-MW solar array.
The primary objective is to minimize the generation cost and environmental impact of microgrid systems by effectively scheduling distributed energy resources (DERs), including renewable energy sources (RES) such as solar and wind, alongside fossil-fuel-based generators.
A microgrid is a localised energy system that can operate independently or in conjunction with the larger electrical grid. It typically consists of distributed energy resources such as solar panels, wind turbines, batteries, and generators, along with control systems to manage energy production and distribution.
Table 1 mentions that the upstream limit of the grid is 80 kW, i.e. the grid can sell up to 80 kW an hour. This is more than twice the downstream limit of the grid which is 30 kW only. In other words, the grid is acting as an infinite source of power for the subject microgrid system.
