Modeling of a Hybrid System for Current and Future Energy Sustainability with Improved Economic Developments Using Present Grid Network Topology

Abstract

Sustainable development can be achieved through; energy sustainability, industrial revolution, political stability, improved agricultural sector and mechanized farming, improved and adequate transportation network, adequate communication infrastructure, etc. Developing a sustainable Energy model that drives economic development is timely. A nation’s energy availability as in Nigeria, where numerous economic activities pose a challenge. It is observed that many of these private sectors, such as Manufacturers, run petrol or diesel generators, which add to air pollution. The nation is challenged by the presence of these dangerous gases. This makes it necessary to improve the energy mix using a hybrid system. Thus, this paper models a hybrid (Solar PV, Wind, and the National grid) automated power system to provide constant energy to the thickly populated nation with diverse economic activities, thereby guaranteeing energy stability, reliability, and security.  The work is aimed at providing sustainable power that is environmentally friendly, less expensive, and has low maintenance costs. The model is developed using ETAP software, which gives a better and reliable solution to power system utilizations and sizing. The present and future worth, initial cost, maintenance cost, solar irradiant, and load demand estimate were among the parameters of interest considered. When comparing the results with different energy sources in the network during simulation, it is observed that the renewable in the network has an 80.8% penetration level, and power quality availability rose 81%, the system witnessed 35% reduction in maintenance cost. These results justify the proposal of a hybrid system compared to a stand-alone system.
