Technical, Economic, and Environmental Analysis of Solar System with Management Considering Flexible Energy Sources in an Educational Building

Abstract

Decades of persistent power outages in Iraq have triggered economic, environmental, and technical woes. Building-integrated solar energy offers a compelling solution. This study explores the viability of a hybrid system combining renewable and conventional sources to power an educational building. Technical and economic analyses using SAM software identified a (PV-DG-Battery-Grid) HES with 5.6kW PV, 400kW DG, 5.5kW inverter, and battery bank as the most feasible, optimal, cost-effective, and environmentally friendly option. Further analysis assessed the impact of factors like solar radiation, fuel price, battery state of charge, cost of energy, performance, and CO2 reduction. Solar panels are estimated to generate 10,210 MWh/year. This research promotes the shift towards renewable energy integration in Iraqi buildings, supporting improved energy management and a more sustainable future.
