Sizing of hybrid energy systems

The aim of this study is to size small hybrid energy systems which have renewable energy. In this study, hybrid energy system has wind turbines, solar panel groups, battery groups and diesel generators. We will search which configuration is economical to provide necessary load. A Matlab algorithm is developeded to size the system. Wind speed data, solar radiation data ve temprature data of Çanakkale are used for sample application. It is searched that if wind energy or solar energy is economical and also if usage of diesel generator is economical.Iterative approach is used for sizing study. Necessary inputs including data of wind turbines, solar panel groups, battery groups and generators are loaded to the algorithm. After the algorithm is run, it is seen that which configuration would be economical. Algorithm checks standards of loading of diesel generators and eliminates generators that are not operating within standartd limits.Present value method is used for all costs in project duration. For each system, all costs are calculated as total net present cost.Also different configurations are tried and differences of the cost per unit of energy are seen.Renewable energy sources, wind energy energy, solar energy and diesel generators are introduced in the first chapter.Criteria for the algorithm, input datas, how algorithm works, how to select economical systems with an iterative approach and in which format the datas should be loaded are introduced and explained in Chapter 6. How the wind turbines, solar panel groups, battery groups and diesel generators are modelled is explained also in Chapter 6Loading standards of diesel generators and how these standards are considered in the algorithm explained.Sample application was modelled. After necessary datas of turbines, panel, battery and generators are loaded to the algorithm, economical configuration is obtained for providing necessary load and details are explained in Chapter 7.Results of analyses are discusssed and related studies which can be searched or developed for future are mentioned in Conclusions and Suggestions.
