Abstract
Integrating renewable energy (RE) systems into the national grid can lead to intermittent supply, degrade power quality, and pose economic challenges. A smart grid (SG) technology is optimized to identify the most efficient plan for incorporating alternatives. This paper examines the techno-economic feasibility of a hybrid RE system connected to the national grid. Large-scale cases are taken to predict the economic statement that a country needs to upgrade, utilizing the same infrastructure. The HOMER Grid tool is used in the current work to simulate three load cases at the country and city levels. The integration of RE sources has participated in up to 19.4%, 219.4%, and 18.24% in Case A, Case B, and Case C, respectively. The affordable cost of energy (COE) was determined at the highest penetration of RE sources. The COE has likely remained close to that of the national grid when it provides the electricity; the value of COE has ranged between $0.0686/kWh and $0.0706/kWh. This research recommends utilizing RE sources in conjunction with the national grid in a country with an abundance of non-renewable energy sources. The future of this study is to extend the simulation for a design software to implement the suggested systems with local weather station.
