Abstract
In this paper the majority of research refers to the optimal configuration of hybrid system that uses renewable energy and wind energy and solar radiation in association with diesel aggregate and batteries. These independent energy systems (hybrid systems) are becoming popular due to increasing energy costs and decreasing prices of turbines and Photo-Voltaic (PV) panels. But the only drawback is that their outputs depend upon the climatic conditions. The main goal to optimization a hybrid system is necessary to obtain the configuration of the system as well as the control strategy that minimizes the total cost through the useful life of the installation to meet the desired consumption and/or the pollutant emissions. The HOGA (Hybrid Optimizations by Genetic Algorithms) program was used to simulate the system operation and calculate technical economic parameters for each configuration. The system configuration of the hybrid is derived based on the data of wind and solar radiation which are related to the southern Croatian coast, as on a theoretical annual load at an observed location. Also, technical data for components are taken from the manufacturer’s specifications (datasheet). In this paper the advantages and disadvantages of commonly used types of generators (synchronous and asynchronous generators) are presented. Results show that the hybrid systems have considerable reductions in carbon emission and cost of the system.
Highlights
Today one cannot imagine life without some form of energy such as electricity
Almost 13.5 % of energy is derived from nuclear power plants, and only 9.8 % of energy comes from renewable sources (Energy Markets in the European Union in 2011)
Genetic Algorithms (GA) searches for the optimum system configuration which involves deciding on the mix of components that the system should contain, the size or quantity of each component, and the control strategy the system should use (Sopian et al, 2008)
Summary
Today one cannot imagine life without some form of energy such as electricity. The main source of energy has been fossil fuels, which provide 85-90 % of energy. A combination of different but complementary energy generation systems based on renewable energies or mixed (with a backup of Liquefied Petroleum Gas /diesel/gasoline generator), is known as a hybrid power system. Hybrid systems can provide a steady communitylevel electricity service, such as marine, village or lighthouse electrification, offering the possibility to be upgraded through grid connection in the future. Due to their high levels of efficiency, reliability and long term performance these systems can be used as an effective backup solution to the public grid in case of blackouts or weak grids, and for professional energy solutions such as telecommunication stations or emergency rooms in hospitals. GA researches combinations of resources which can satisfy the load with the lowest cost (Dufo-López et al, 2005)
