CENTRALIZED AND DISTRIBUTED OPTIMIZATION OF LOAD DISPATCH PROBLEM INCORPORATING DISTRIBUTED GENERATION

Abstract

Economic dispatch (ED) is an important problem in power system operations. With the increasing environmental concerns, the traditional power system is facing a problem of increasing penetration of distributed energy resources (DERs). The thesis starts investigating the ED problem from the micro-grid islanding operations by two multi-objective optimization algorithms. Furthermore, the thesis investigates the ED problem of the distribution network with distributed energy resources. Additionally, the thesis proposed a novel consensus based algorithm to solve ED problem in a distributed manner. On top of that, the thesis improves the existing distributed ED algorithm in literature by bringing loss information into consideration.
