1) Will the microgrid be connected to the main power grid? If the microgrid is grid-connected (i.e., connected to the main electric grid), then the community can draw power from the main electric grid to supplement its own generation as needed or sell power back to the main electric grid when it is generating excess power.
plants remain the least costly deployment of solar power due to economies-of-scale in construction and operation, and the ability to locate in the areas of best solar resource. • Without energy storage, PV generation does not provide all of the characteristics necessary for stable grid opera-
