Simulation and optimisation of renewable energy systems

In recent years, in parallel to increase of population,technology and industry in order to provide the need of energy alternative energy resources have become important. At the same time, fossil energy resources has many harmful effects on the environment. For this reason it is aimed to find alternative energy resources.as a result of this, Renewable Energy resources have been developed rapidly to meet the increasing Energy demand.One of the most important advantage of Renewable Energy energy resources is forming hybrid system with other energy resources.Perminance of energy can be provided in places where grid connection does not exist by using hybrid system.In this thesis, Renewable energy resources ,hybrid systems,cost optimisation of energy that is produced and the factors that affects cost are described.Homer computer programme that is used for these purpose is described, two different sample system projections are given. From the obtained data it is achieved that, although it increases the initial costs, the connection of battery and diesel generators are reqired because of Energy perminance and the connection with grid decrases a lower system costs.Key words: Renewable Energy Resources,Hybrid Systems, Simulation and Optimization of Renewable Energy Resources,HOMER programme
