Techno-Economic Dispatch of Distributed Energy Resources for Optimal Grid-Connected Operation of a Microgrid

This paper is worried about the electricity dispatch trouble of distributed generations (DGs) for optimum operation of a microgrid. The goal is to lessen the fuel cost through the grid-linked operation while making sure stable operation after islanding. To reach this purpose, a techno-economic dispatch model and associated limitations are expressed. Reserve for modification in consumers load, flow limits among two adjoining regions, and reserve for the stable islanded operation are some of these limitations that are considered in this paper. These constraints are used inside the ED model for traditional systems, are changed to use Microgrids. Moreover, a comprehensive model is presented for the stable islanded operation of the microgrid under fixed and adjustable droop conditions. In this paper, a modified direct search approach is considered to solve the suggested problem; and the impact of the proposed method on the cost objective function is studied.
