In this study the geometrical optimization of monolithically integrated solar cells into serially connected solar modules is reported. Based on the experimental determination of electrodes0 sheet and intermittent contact resistances. the overall series resistance of individual solar cells and interconnected solar modules is calculated. Taking a constant photocurrent generation density …

This paper presents a 24 hour ahead microgrid power planning using the approach of unit commitment by dynamic programming. The studied system comprises twelve PVbased active generators with embedded storage and three micro gas turbines. Based on the prediction of the energy available from the PV generator. the storage availability. …

Decentralized electricity generation by renewable energy sources offer greater security of supply for consumers while respecting the environment. But the random nature of these sources requires us to develop sizing rules and use these systems to exploit them. This paper proposes an integrated PV wind hybrid system optimization model. which …

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 …

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 …

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 …

Artificial neural networks with six inputs have been developed in order to identify an accurate model site-specific wind turbine performance. Results of this modelling technique were compared with parametric. non-parametric. and discrete methods. For the two turbines studied. it has been demonstrated that the strategic incorporation of 6 inputs in …

This research paper presents an accurate and fast algorithm to identify the optimum location and size of large scale PV units in sub-transmission networks to reduce reactive power losses. It can be concluded that the integration of large scale unity power factor operated PV unit provides positive outcome in terms …
