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
