This paper investigates the role of reactive power compensator STATCOM and presents a control system based on simultaneous control of STATCOM reactive power and pitch angle of rotor blades for improving stability margin of speed of induction generator. As it can be seen in Fig. 12. critical clearing time i.e. …

This paper presents Genetic Algorithm based reconfiguration scheme for the arrangement of PV modules in a PV array which exhibits increased array power generation under partially shaded conditions. The reconfiguration technique involves changes in the electrical interconnections for shade dispersion keeping the physical location of the PV modules unchanged. The …

In this paper. a modeling method based on the genetic algorithm is proposed. The values of the PV module parameters were computed in such a way that the error between the simulation results and the data sheet information is minimized. A global optimization for the values of the parameters was …

Based on silver nanoparticle arrays and blazed grating arrays. we have designed structures of thin film silicon solar cells both at the front and the rear surfaces. In the design of the front surface of the cells. silver nanoparticle arrays have been placed in order to increase the light transmittance …

This book provides a unique multi- and interdisciplinary approach to energy conversion technologies by shedding light on the topic from both technological and ethical perspectives. It applies these concepts to examples of engineering problems related to energy conversion – an internal combustion engine and a fuel cell – in order …

In this paper. a novel type of CPC-SAC is presented. A series of experiments was conducted in 2014 in Beijing. China to investigate the thermal performance of the novel SAC. The collector exhibited a stable performance during the test period. with an annual average thermal efficiency of 52%. The novel …

In this paper. a comprehensive electrical modeling of PV has been carried out and a generalized PV simulator has been proposed and designed in MATLAB Simulink software package. The proposed simulator has been developed as a masked block. It can simulate any number of panels connected in series and parallel. …

Based on the proposed technique. a two stage power electronic system architecture has been proposed as shown in Fig. 5. The system comprises of a boost type dc–dc converter and an inverter to feed the power generated by PV array to the grid and grid connected loads. The system configuration …

The goal of this study was to detect barriers to and opportunities for promoting nearly zero-energy dwellings on the basis of end-user experiences. by studying end-user satisfaction with nearly zero-energy houses. Developments in Germany and Austria (mainly the building of passive houses) are related to the European requirement for the …

For all we know today. and for all we can learn from history. the convergence of national energy intensity levels at lower and lower global values should continue—as long as economic openness allows global fuel trade. the exchange of technical knowledge and the standardisation of products to continue. Likewise. fuel …
