Micro-Grid with PV, Fuel Cells, and Energy Efficiency

    Research output: Contribution to conferencePaper

    Abstract

    A micro-grid is an electrically isolated set of power generators that supplies all of the demand of a group of customers. This work evaluates the potential of a micro-grid composed of photovoltaics (PV), fuel cells, and energy efficiency investments and a set of residential customers. It concludes that: (1) PV, fuel cells (operated in a cogeneration mode), and energy efficiency may all be aneconomically attractive part of a micro-grid; (2) there is a fairly good match between supply and demand on an annual, monthly, and hourly basis; (3) fuel cells (operated in a cogeneration mode) and PV complement each other in terms of electricity supply because fuel cell electricity production peaks in the the winter while PV electricity production peaks in the summer; (4) a relatively smallnumber of customers (less than 50) can result in a reliable micro-grid; (5) customer loads that are more certain result in a smaller micro-grid; and (6) micro-grids may represent a new market for PV, fuel cells and energy efficiency.
