Techno economic evaluation of a hybrid energy system

Abstract

Use of renewable electricity resources has proved to be a more reliable and cleaner solution now-a-days. Photovoltaic units, wind turbine units have been considered as these are the most commonly used renewable energy generators today, but these generators involve high values of losses and are highly expensive. This paper presents a multi objective optimization using the Matlab GAtool. The algorithm is executed on a test system of 69 buses. The results of the case study show that proper positioning of renewable energy generators and sizing can lead to improvement in voltage profile, reduction in power losses and reduction in cost. Cost analysis of this framework is performed using Homer Pro3.8.1 which shows that this hybrid energy system is more efficient and economical than using of a single renewable electricity generator or combinations of renewable electricity generators of different sizes for a variable load profile. The advantages of this algorithm include its accuracy, calculation speed and the reduced values.
