Hybrid optimization algorithm for modeling and management of micro grid connected system

Kallol ROY,Kamal Krishna MANDAL

Frontiers in Energy 2014, Volume 8, Issue 3,   Pages 305-314 doi: 10.1007/s11708-014-0308-8

Abstract: In this paper, a hybrid optimization algorithm is proposed for modeling and managing the micro grid (MG) system.The management of distributed energy sources with MG is a multi-objective problem which consists of windturbine (WT), photovoltaic (PV) array, fuel cell (FC), micro turbine (MT) and diesel generator (DG).Because, perfect economic model of energy source of the MG units are needed to describe the operating

behavior of Fe–Cr–Ni based alloys exposed to molten MgCl2–KCl–NaCl salt with over-added Mg

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 10,   Pages 1608-1619 doi: 10.1007/s11705-023-2349-1

Abstract: Adding Mg into molten MgCl2–NaCl–KCl salt as a corrosion inhibitor is one of the most effectiveafter 500 h immersion test at 700 °C when the alloy samples directly contacted with the over-added Mgindicates that Ni preferentially leaches out of alloy matrix due to the tendency to form MgNi2/MgThese results suggest that direct contact of liquid Mg with Ni-containing alloys should be avoided duringusing Mg as a corrosion inhibitor for MgCl2–NaCl–KCl or other chlorides for high temperature

Frontiers in Energy 2013, Volume 7, Issue 4,   Pages 413-428 doi: 10.1007/s11708-013-0274-6

Abstract: This can be envisioned through the implementation of concepts of smart grid (SG).One of the key requisites for SG implementation is that the grid should be completely observable.Renovation of conventional Indian power grid to a SG necessitates incorporation of the phasor measurementunits (PMUs) in the present power grid measurement and monitoring system.The results proposed in this paper can be a stepping stone for revamping the Indian power grid to a SG
