Simulation and Analysis of the Effects of Distributed Generation Using Solar, on the World Bank 11kv/415v Distribution Feeder Network

Abstract

The solar insolation level affects the output voltage of a PV cell, which is a function of photo current. At the client load location, electrical power generation systems known as distributed generation (DG) are produced. Wattage losses can be reduced, and improvements can be made to the voltage profile and power quality. When constructed appropriately, it saves money by reducing the need to invest in transmission and distribution infrastructure. The 11/415 kv Distribution Network (DN) of the World Bank has been taken into account in this analysis. The findings also demonstrate that DG integration on these specified buses can increase both the voltage on the vehicle and the flow of power to adjacent buses. Two scenarios were considered for situations when there are bus voltage lapses in the distribution network after the power flow analysis was completed with and without the DG. The function of photo current and the level of solar insolation determine the PV cell's output voltage. The integration of DG at this bus would compensate power at the bus and other buses based on the loads on other buses, it was found by examination of bus voltages and voltage differences. The research methodology included the actual collection of essential data from a typical modern Nigerian electricity distribution network, making this study immensely beneficial to society and the country as a whole. The network was modeled using a program named Electrical Transient Analyzer Program [ETAP 16.00]. The bus voltages, power losses, and load flow data for the current network were computed using the Newton-Raphson power flow method by the ETAP 16.0 program
