Quantification of economic, environmental and operational benefits due to significant penetration of Microgrids in a typical LV and MV Greek network

Abstract

AbstractThe effect of the use of a Microgrid Central Controller (MGCC) to achieve co‐ordinated operation of various DG sources, storage devices and controllable loads with regards to the potential economic benefits and the power losses avoided in the local network is presented. Additionally, the effect of connecting numerous typical Microgrids in a typical medium voltage (MV) network regarding power losses and the emissions avoided is studied. The emissions avoidance calculation is based on the marginal emissions curve of the upstream network, quantifying also the calculated losses reduction impact on emissions avoidance. The presented results, based on a variety of realistic market prices time‐series, various levels of renewable energy resource (RES) production and demand from different seasons, show clear benefits in terms of both losses and emissions avoidance. Finally, this paper performs a sensitivity analysis on the potential impact of the DG topology within a Microgrid on losses and emissions avoidance. Copyright © 2009 John Wiley & Sons, Ltd.
