Abstract

There is a remarkable growth and an increasing demand of clean and renewable energy for power generation, especially in remote areas. Its extensive usage lowers carbon footprint. In this paper, effort has been made to analyze a Hybridized Wind/PV Energy System considering both solar and wind power. The focus is to give a cost effective and optimal solution to solve the problem of energy transmission in the telecoms industry, especially in the remote areas of Nigeria. Wind and solar alone can fluctuate, however a practical approach from a hybrid system gives an economical and a reliable energy flow overall system. Containerized diesel generator was utilized as backup when the storage is low, and blackout is experienced. Energy estimation models and HOMER-PRO were used for simulation and optimization. Various system configuration was tried based on technical constraints and Net Present Cost (NPC). Results obtained shows that the base system is with NPC of 166 million, while the current system is with NPC of 51.4 million. The current system was selected which gives an optimal value of each decision variable that satisfies technical constrains at the lowest cost though with a higher capital. The hybrid system consists of 3 kW wind turbine, 3.66 kW converter, 69.1 kWh lead acid battery and a 25kW generator. Over the simulated annual chronological dispatch, the wind turbine gives power output of 5,055 kWh/yr which is 13.5% of the total power output, PV gives 31.092 kWh/yr, which is 82.7% and the annual renewable penetration of the hybrid system is 92.8%. This shows to what extent the telecoms industry can depend on clean and green energy.
