Abstract The power sector has been facing the problems of the continuous increase in demand and lack of sufficient generation of electric energy using fossil fuels. The environmental problems (pollution and global warming), the continuously increasing cost of fossil fuels and the shortage of fossil fuels are mainly concerned to harvest energy from sustainable and clean sources. One of the promising sustainable energy sources is solar energy. Electrical energy can be produced from solar radiation...

Abstract An investigation of auto-reconfiguration scheme for interchanging the electrical connections of photovoltaic (PV) array of 3 × 3 size, from series-parallel (SP) to total cross-tied (TCT) configuration under partial shading conditions (PSCs) is presented. The progressive increment shading patterns- 1, 2 and 3 are considered for the extensive comparative analysis for experimental and MATAB/Simulink system. The experimental system comprises three sections: under section I, four relays are ...
Abstract Solar photovoltaic (SPV) systems can be used to harvest the energy of sunlight in the form of direct current, but even a slight objection to the direct sunlight via any static or dynamic obstacle amidst the two can cause the condition of partial shading that may result in a lower output power than the array rating, increased losses due to overheating and multiple peaks. This can be mitigated via the use of bypass diodes, micro-inverters and reconfiguration of the SPV system under partia...

In the paper presented, the operational functioning of fuel cell (FC) systems is introduced by designing of reactant flow pressure controller. A suitable design for controller is very necessary to enhancement of overall system performance. In order to govern the power of PEMFC (Proton Exchange Membrane Fuel Cell) an adaptive Fuzzy logic (FL) based controller is designed. A MATLAB/Simulink model is designed for the PEMFC based power generation system using efficient controller for the FC power ma...

Abstract The efficiency of the photovoltaic (PV) system is directly proportional to the solar energy. The maximum efficiency from the PV systems can be achieved if the panel is kept perpendicular to the direction of the radiations of sun. Hence, in order to achieve maximum concentration, radiation and efficiency of the PV cell, tracking of the position of the sun with accuracy is extremely important. The various methods of sun tracking system have been discussed which includes two axes, one axis...

This paper develops a dynamic model of small-scale wind energy conversion system (WECS) based on diode bridge rectifier and permanent magnet synchronous generator (PMSG). The simple and effective perturb and observe (P&O) algorithm has been proposed for extracting maximum power point tracking (MPPT) of wind turbine (WT) in the moderate-to-cutout wind speed region by sensing input parameters of DC–DC buck–boost converter. The MPPT algorithm in addition to the DC–DC converter is being simulated in...

In this research an embedded-based procedure for automatic fault detection and supervision in 2 × 2 PV array with possible fault allocation by using voltage and current parameter through embedded. The supervision system is developed with LabView which is acting as real-time data logger. The approach has been validated with experimental setup, and the system is designed with low-cost embedded-based solution to provide reliable and secure monitoring of PV system. The system include the parameter e...
