Efficiency of Hybrid Power Stations and Factors Affect the Efficiency

In this paper the performance and efficiency of hybrid power stations are studied, taking into account the factors affect on hybrid types stations. This will include using good tracking solar system, good photovoltaic cooling system for solar cells and vibrations of the wind structure. Efficiency of solar systems affected by temperature increases, the efficiency of such systems can be increased by using some type of cooling for photovoltaic cells and panels. Power generated from wind turbines are effected by vibrations of wind turbines towers and structures, decreasing the values of such structures may increase the output power of wind turbines stations by a considerable values. An equation to calculate the overall efficiency of hybrid power plan is generated. The overall efficiency of combined or hybrid power plant is calculated and it reaches to 70%. It is found that there are many factors affects the final energy produced from hybrid energy systems (solar and wind). Two main factors are studied here: high temperatures, and vibrations both have a bad effect on the performance of the energy systems. As the temperature and vibrations increased the efficiency of the energies system (single or combined) is decreased. Hybrid power plants reduces costs, spaces and improves the overall efficiency of the renewable energy systems.
