Abstract: Microgrid is a local conglomeration of sources and loads that operate based on point of common coupling (PCC) status. This paper proposes a wireless Central Protection Center (CPC) that remotely monitors a microgrid that acts with PCC closed. The data acquisition takes place on a LabVIEW based operator console. The microgrid is initially bifurcated into smaller zones, to facilitate easier monitoring. The CPC monitors as well as captures the current operating status of the individual zones of the microgrid. Overcurrent coordination of relay (OCR) is a highly constrained optimization problem and an optimum relay setting using Dual Simplex Algorithm is required to minimize time dial setting of overcurrent relays which eventually facilitates it achieving minimum time of operation of relays and swift fault clearance. If an overcurrent fault is diagnosed by the CPC, then an optimum overcurrent relay coordination scheme is adopted by the zones of the microgrid.
