Capacity credit of microgeneration and microgrids

The recent development of the concept of microgrid ([mu]Grid), associated to the emergent interest in microgeneration ([mu]Gen), has raised a number of challenges regarding the evaluation of the technical, economical and regulatory impacts of a high penetration of this kind of solutions in the power systems. In this paper, the topic of security of supply is addressed, aiming at evaluating the influence of [mu]Gen and [mu]Grids in the medium- and long-term availability of generation to serve the forecasted load. A Monte-Carlo based methodology is used to evaluate this influence and to assess the capacity credit of those entities.
