Solutions and Energy Management Optimization for Hybrid Renewable Energy System at Babylon University, Engineering College, Iraq

Abstract

The design of hybrid energy systems requires sustainable resources and main components such as energy management. The Iraqi government has advised educational facilities, such as universities, to use renewable energy resources to reduce electricity consumption because Iraqi energy supply systems depend mainly on fossil fuel. The loads in Iraq have expanded during the last few years while generation stations and networks have remained the same. Therefore, hybrid optimization of multiple energy resource software has been used to investigate possible solutions that can be applied to generate the required power for Babylon University, Engineering College. Eight on-grid cases were examined for producing the required power. Grid-WTBT(Case4) which has the lowest cost of energy (COE) and net present cost (NPC) value with 51.8% renewable energy penetration was found to be the most feasible. The results showed that the Grid (1,964,518 kwh/y), NWT (50), NBT (4), Nconv (2), COE (0.0677 US$/kwh), NPC (US$3.19 million), and IC (US$ 853,031). Moreover, the energy requirements of AC primary load in this college can be satisfied by using this system.
