The photovoltaic (PV) systems exhibits nonlinear I-V characteristics and maximum power point varies with solar radiation or insolation and temperature. An intermediate pulse width modulation dc to dc converters can increase efficiency of the system by providing impedance matching between the PV system and the load and operating the PV cell arrays at their maximum power point using MPPT techniqu...

The ascending trend of photo-voltaic (PV) utilization on a domestic scale in Finland, calls for a technical aspects review of low voltage (LV) networks. This work investigates the technical factors that limit the PV hosting capacity, in realistic case networks, designed relative to different geographical areas of Finland. A Monte Carlo method based analysis was performed, in order to quantify t...

A fuzzy based three phase inverter with single DC source for grid connected photo voltaic (PV) system employing three phase transformer is presented in this paper. Space Vector Pulse Width Modulation (SVPWM) control scheme is effectively used to generate the appropriate switching sequences to the inverter switches. The intend of the fuzzy logic approach is to meet high quality output, minimum T...

<span lang="EN-US">Nowadays, non-conventional energy sources like solar, wind, geothermal, and small hydro play a vital role in generating electricity. Among these, solar is utilized urban rural areas. When the sunlight falls on plate, PV cell produces charge carriers that produce an electric current. A photo voltaic used when it works at maximum power point. Traditional point tracking (M...

Innovation became important years ago when people became interested in the dynamic underlying economic development and growth. And innovation has been intimately intertwined with entrepreneurship. Joseph Schumpeter, writing in the early 20 C, argued that innovation is central to economic development; he regarded entrepreneurs as innovators engaged in a process of creative destruction, destroyin...

The paper is concerned with determining the optimized active areas of a photo voltaic conversion system, of a group of electricity generating wind machines and the optimal capacity of a battery storage system for a combined power plant. Minimization of the total life-cycle cost of the system is the criterion to obtaining the optimized parameters of the system. The algorithm consists of generati...

This paper proposes Particle Swarm Optimization (PSO) based approach for light intensity control in a Photo Voltaic (PV) supply fed LED lighting system. The output power regulation of LED lighting system is formulated as an optimization problem and the output power regulation is carried out using a real time PSO technique. The concept is first simulated and verified and subsequently implemented...

To investigate the variability in energy output from a network of photo-voltaic cells, solar radiation was recorded at ten sites every ten minutes in the Pentland Hills to the south of Edinburgh. We identify spatio-temporal auto-regressive moving average (STARMA) models as the most appropriate to address this problem. Although previously considered computationally prohibitive to work with, we s...
