Abstract
A comprehensive theoretical investigation validated by the measurement is necessary to assess the impact of a microgrid on the electric distribution system. Some key parameters worth investigating are- enhancing economy, reliability, quality, and resiliency of a microgrid. Considering this necessity, a study of energy delivery system in a microgrid and its financial feasibility to integrate into the energy infrastructure has been presented in this paper. A campus microgrid with energy-efficient combined heat and power (CHP) natural gas-fired microturbine and photovoltaic generation has been used as a testbed to evaluate the efficiency of the power delivery. With distributed control and communication capability, this microgrid can be considered as a building block of smart grid that facilitates the inclusion of renewable and energy-efficient distributed generation. Simulation work has been performed to study the economic feasibility to integrate such microgrid into the energy grid. Several cases of remote microgrid operation have been studied to compare the best possible solution.
