For the continuous functioning of the CSP plant during the night and in overcast days a thermal energy from the heat tank or gas as an additional source of energy is used (Sharma, 2011 Kaygusuz, 2011). Solar concentrators can be parabolic troughs, heliostats, parabolic dishes and Fresnel reflectors (Robert, 2007). CSP plants are composed of the solar concentrator, steam turbine and electricity generator. Concentrated Solar Power (CSP) plants denote plants that generate electrical energy by means of concentrated sun irradiation. For low-temperature solar energy conversion one uses flat collectors with water and air, for middle-temperature conversion one uses vacuum collectors and collectors with concentrators, and for high-temperature one uses solar furnaces and CSP plants (Tomislav, 2007) and (Fernández-García et al., 2010). Depending on the degree of the heating of the working fluid we can differ between the low-temperature (T<100 oC), middle-temperature (100 oC Many areas in the world abound in free solar energy while in some other areas wind and other types of renewable sources of energy impose themselves as a logical choice (Marković et al., 2011). Renewable sources are in the long run a valuable alternative. Irrespective of the ecological arguments increase of the production of electrical energy generated by renewable sources is necessary so that countries diminish their dependence on the import and the necessity to provide for new resources. It is estimated that the consumption of electrical energy will double in the next 15-20 years. Global increase in the number of population and this same increase in fortunes bring about increased consumption thus creating lack of resources especially sources of energy and drinking water. Physical and mathematical model is presented, as well as numerical procedure for predicting thermal performances of the P2CC (Parabolic-and-Circular Collector) solar concentrator. The results of this research may be applied in the construction of small solar systems, but also in the design and construction of large polygeneration systems. Solar systems referred as mid temperature (100–400 oC) are considered suitable for integration with industrial processes, cooling, and polygeneration systems through use of concentrating solar collectors. The cases in which solar cells are used to generate electrical energy are very rare. In addition, the examples and technical characteristics of some concentrating solar power plants in the world are given. AbstractIn this chapter, description and working principles of the parabolic trough power plants, solar tower power plants, parabolic dish power plants, and power plants with Fresnel reflectors in the world and their potential use in Serbia are given.
