Identifying Energy Trends in Fiji Islands

Abstract

This chapter intends to simulate the current situation of Fiji Electricity Authority’s transmission network of Viti Levu by using the load flow method and investigate the situation of the overall system. The first part of the chapter focuses on finding out the problems faced by Fiji Electricity Authority with the reliability of the network. After inspecting regions vulnerable to faults, different scenarios have been tested in steady state with different loads in various parts of Viti Levu. Reaction of the network was observed to determine the highest load level that the network can support before collapsing. The second part of chapter proposes recommendations to improve the reliability of the network. These recommendations are tested using the ETAP software in the form of scenarios by incorporating different possible choices with the current network, and the results obtained from each scenario are analyzed. This chapter concludes with the listing of recommendations that can be made in order to do further analysis for future expansion of the network through renewable energy sources (RES).
