Energy Conversion System

In this study, a simulation model of in-grid solar-to-electrical energy conversion system is presented. In this case, the in-grid solar-to-electrical energy conversion system is small photovoltaic power plant, which was constructed by the Center for Renewable Energy and Power Quality from Faculty of Technical Sciences (FTS). Equivalent circuit diagram of photovoltaic cell is described which was used to develop the simulation model of modules. Possible types and topologies of inverters are also described. The photovoltaic power plant is described briefly, because it is necessary to understand the simulation model. The result of simulation is an electricity annual production by the power plant. These results were compared with the real values, while its get a good overlap. The paper also presents the modern modeling methods developed at Faculty of Technical Sciences in the Laboratory for RES systems.

Electrical energy demand increases day-by-day due to economic growth, technology development and increasing world population. The wind is one of the accessible renewable energy sources to generate electrical energy to meet the increased load demand. When the wind energy conversion system (WECS) is operating as isolated mode, it is more reliable, economical and easy to electrify rural areas. When the WECS is connected to load without controller the output three-phase voltages of the inverter have more transient and steady state errors and higher total harmonic distortion in the voltages and currents. This paper discusses various voltage controllers used in WECS in detail. The proposed WECS is simulated using MATLAB/Simulink with and without adaptive voltage controller for balanced and unbalanced non-linear load conditions. In each case the results have been analyzed and total harmonic distortion is evaluated..

The sustainable development of clean and efficient electricity generation techniques accelerated the research for invention of alternative electricity generation methods. In this chapter, the conceptual analysis of newly invented photon-enhanced thermionic emission (PETE) energy conversion process has been presented. It is a promising option for harvesting solar energy in terms of capturing photon as well as thermal energy simultaneously and converting solar energy into electrical energy based on photovoltaic and thermionic emission processes of energy conversion. Thus, the PETE process utilizes photons for PV conversion and heat of radiation for thermionic emission process. The main objective of this chapter is to review and analyze the performance of PETE converters including thermal modeling, choice of materials, and parametric optimization. The appropriate choice of material requirements for cathode and anode of PETE converters is necessary for practical design of PETE converters. The PETE converter may be an efficient future option for electricity generation using solar energy.
