An Intuitive LabVIEW VI for Optimal Dispatch Scheduling with a Full AC Power Flow for Loss Calculation

Abstract

In this paper, we present a Virtual Instrument (VI) developed in LabVIEW to solve the optimal power dispatch (OPD) scheduling problem of power generation, while using traditional methods to solve the Power Flow (PF) problem in order to include the transmission losses iteratively in the OPD problem. The objective is to minimize the production cost required for the production of electrical energy which is presented in the form of a nonlinear function, by taking into account of certain equality and inequality type constraints. The losses in OPD problem are calculated iteratively using a full ac power flow formulation. The adequate choice of this graphical (G) language is illustrated by comparing the results obtained by the proposed VI with those of many references. The effectiveness of the proposed VI is identified through its application to themany test system. Computational results manifest that the VI has a lot of excellent performances.
