Deployment of Power Network Structural Topology to Optimally Position distributed Generator within Distribution System

Abstract

Distribution system is very essential to load centre or service mains. This is because it is the final section of electric power system (EPS) to supply the consumers. Once this section is compromised, low voltage consumers will be denied of a reliable supply of electricity. One way to make supply to low voltage consumers reliable is by bringing generation close to them through distributed generators. However, location of distributed generator is very important with respect to the entire EPS security. In this study, power network structural topology (PNST) is proposed to optimally locate distributed generator within distribution system which results in minimal loss as well as maintaining voltage profile within constraint limits. 5bus IEEE test system was used as case study to show the feasibility of the proposed method. Results obtained for both test systems were validated through the results from power world simulation tool.In this section, power network structural topology (PNST) and power world simulation software are considered. The PNST is the proposed approach in this study while power world simulation software is used to validate the result obtained from PNST. Power network structural TopologyPower network structural topology (PNST) is an approach that considers the inherent characteristic of electric power circuitry in order solve power system problems. PNST approach proposed in this study, is based on the two-port network technique which has been reported in previous works [15][16][17].

Techno-Economic Assessment of Wind Turbines in Nigeria

“…Energy is among the essential needs of economic development (Babatunde et al, 2020;Oyedepo et al, 2012;Somefun et al, 2020), in meeting the world high energy demand. The significant sources of energy in use have been conventional fossil fuels (Mohammadi et al, 2014).…”

Investigation of the Impact of Distributed Generation on Power System Protection

“…Integration of distributed generation (DG) into the distribution systems offers many advantages and disadvantages to the distribution network [1,2]. Economic and environmental benefits, and increased penetration of DGs, will impose significant technical barriers on the efficient and effective operation of the distribution systems.…”
