This review-paper focuses on the latest development of modelling and control of grid connected photovoltaic energy conversion system. Modelling of photovoltaic systems include modelling of SPV array, power electronics inverter/converter based on MATLAB/SIMULINK. This present control algorithm of a three-phase and single phase grid-connected photovoltaic (PV) system including the PV array and th...

It is a great challenge for DC microgrids with stochastic renewable sources and volatility loads to achieve better operation performance. This study proposes an energy management strategy based on multiple operating states for a DC microgrid, which is comprised of a photovoltaic (PV) array, a proton exchange membrane fuel cell (PEMFC) system, and a battery bank. This proposed strategy can share...

In the recent years, the solar energy becomes one of the most important alternative sources of electric energy, so it is important to improve the efficiency and reliability of the photovoltaic (PV) systems. Maximum Power Point Tracking (MPPT) plays an important role in photovoltaic power systems because it maximize the power output from a PV system for a given set of conditions, and therefore m...

The floating photovoltaic system is a new concept in energy technology to meet the needs of our time. The system integrates existing land based photovoltaic technology with a newly developed floating photovoltaic technology. Because module temperature of floating PV system is lower than that of overland PV system, the floating PV system has 11% better generation efficiency than overland PV syst...

Purpose Renewable energy components such as Building Integrated Photovoltaic (BIPV) often influence the aesthetic quality of a building adversely and hence need to be analyzed for their impact on building form and aesthetics. This becomes crucial especially in the case of a sun-tracking photovoltaic system. Moreover, there is a need to propose a reasonably accurate but quick system to estimate ...

--A computer based data acquisition system to monitor and control photovoltaic power generation systems using a novel method, based on Campbell scientific data acquisition board (CR3000) and graphical programming software (PC 400), has been designed and implemented. Prior to designing the data acquisition system, a small sized PV power generation system, consisting of a 6.4kw Solar panel, a cha...

During the last decades, human lifestyle and economic growth has had a profound effect on the energetic sector considerably changing the perspective on the energy issue (Ambros et al., 2004). The increasing energy demand and variable oil price, insecure energy resources and carbon dioxide emission have made us aware of the fact that energy is indeed a limited product (Awerbuch, 2002). Regarding...

Recently, the concern for environmental issue has been rising in the world such as global warming by exhausting carbon dioxide (CO2) and breaking of ozone layer by freon gas. On December 1997, during the Kyoto Conference on Climate Change (COP3), it was agreed that by the year 2012 the developed countries would reduce at least 5% of the green house gases compared with year 1990 (Riza et al., 20...

The environmental and energy parameters of Photovoltaic (PV) systems play a very important role when compared to conventional power systems. In the present paper, a typical PV-system is analyzed to its elements and an assessment of the material and energy requirements during the production procedures is attempted. A Life Cycle Analysis (LCA) is being performed on the production system of photov...

There are high hopes and expectations in the potential of Net-Zero Energy Buildings (NZEB) to contribute to combat the adverse environmental effects from intensive human activity, including energy use. An important related question that has received insufficient attention and is therefore addressed in this study, is how NZEB equipped with renewable energy (RE) systems would perform in future cl...
