This paper presents a method to operate a grid connected hybrid system. The hybrid system composed of a Photovoltaic (PV) array and a Proton exchange membrane fuel cell (PEMFC) is considered. The PV array normally uses a maximum power point tracking (MPPT) technique to continuously deliver the highest power to …

This paper proposes a method of modeling and simulation of photovoltaic arrays. The main objective is to find the parameters of the nonlinear I–V equation by adjusting the curve at three points: open circuit. maximum power. and short circuit. Given these three points. which are provided by all commercial array …

We present a non-traditional CMOS inverter composed a junctionless (JL) NMOSFET and an N+ -N–P transistor which with simple process and high integration density in this paper. In the non-traditional CMOS inverter the JL NMOSFET serves as driver and the N–P transistor serves as load. respectively. Based on the measurement …

The battery energy storage station (BESS) is the current and typical means of smoothing wind- or solar-power generation fluctuations. Such BESS-based hybrid power systems require a suitable control strategy that can effectively regulate power output levels and battery state of charge (SOC). This paper presents the results of a wind …

Today. given the population growth in the world. we witness development of industry sector. particularly building construction industry. so as on the one side. we are confronted with fuel consumption increase and consequently uncontrolled production of buildings’ environmental contaminators and on the other side. non-observance of the standards and non-insulation …

The main objective of this paper is to design a computerbased controller for the capacitor self-excited induction generator (CSEIG) using terminal capacitors. The generator is assumed to be a power source in an isolated system. System voltage regulation will be the major requirement of the designed controller. This will be …

Distributed Generation (DG) in the form of Renewable Power Generation systems are currently preferred for clean power generation. However due to their intermittent and unpredictable nature. energy storage needs to be used to ensure that the load is met at all times. There are many possible options for energy storage …

Future large-scale space solar power (SSP) will form a very complex integrated system of systems requiring numerous significant advances in current technology and capabilities. Ongoing technology developments have narrowed many of the gaps. but major technical. regulatory. and conceptual hurdles remain. Continuing systems concept studies and analyses will be critical …

The multidimensional character of renewable energy sources (RES) necessitates the collection of a number of related data in order to support EU policy needs. Apart from the technology and technophysical data also socioeconomic (e.g. employment. turnover) data and R&amp.D expenditures are of critical relevance. The monitoring of the above RES …

A large part of photovoltaic research is dedicated to developing innovative integration technology for the module. Now the use of a storage function in such intermittent power supply systems is crucial in order to get better adequacy between the peaks of energetic consumption and production. The integration degree of photovoltaic …
