WT-Based Distributed Generation Location Minimizing Transmission Loss Using Mixed Integer Nonlinear Programming in Deregulated Electricity Market

Abstract

In this paper, analysis has been carried out for transmission loss minimization with the integration of wind turbine in the power system network. For obtaining the power output from the wind turbine, a probabilistic model for the wind has been considered using Weibull distribution function. A mixed integer nonlinear programming (MINLP) approach has been utilized for determining optimal location and number of distributed generators considering minimization of transmission loss. The main objective of the paper is: (i) transmission loss minimization with wind turbines, (ii) optimal location and sizing of wind turbines, (iii) comparison of results without and with wind turbines considering constant load model and realistic ZIP load model. The analysis has been carried out with constant P, Q load and the realistic ZIP load model. The impact of different load models has also been studied. The proposed MINLP-based optimization approach has been applied for IEEE 24 bus reliability test system.
