A Techno-economic based Integrated Planning Approach from Economic Load Dispatch Perspective in Various Distribution Network Topologies

Abstract

Electricity is the elementary need for the economic growth of any country. Transmission and Distribution (T&D) system plays a crucial role in transferring power from utility to consumer end thus proficient design can lead towards reduced demand and supply gap. Pakistan is facing energy crisis for more than a decade, so efficient T&D system can help in minimizing the shortfall of electricity. This paper offers ways to gratify the combination of Economic Load Dispatch (ELD) with the perspective of planning distribution network while considering Radial Distribution System (RDS) and Mesh Distribution System (MDS). Genetic Algorithm (GA) optimization is implemented for ELD taking in account generation units, generating at different fuel cost for the IEEE 69 base case. Furthermore, a cost to benefit analysis is carried out while discussing different case studies, upgrading distribution network and decrease per kWh cost by considering different techniques.
