In this paper, CO2 emission reduction of Photovoltaic Thermal model for residential load has been investigated and evaluated for four different PV coverage area cases of PVT (20%, 40%, 60% and 80%). The analysis is conducted by using a data set of weather conditions of a city in North America over one year.
Solar sources require using power converters introducing harmonics in the output waveforms. Data used is the solar radiation and temperature in Halifax, Nova Scotia, Canada. In this work we studied the effect of changing the blanking angle of the square-wave inverter with 60Hz switching. The harmonics are evaluated for various temperatures and solar radiation for the optimum firing angle. Also probability...
Conventional non-renewable electrical energy production has become an increasing concern due to its high costs, limited resources, and negative impacts. Scientists have begun to focus their research on renewable energy sources. Renewable energy is generally a clean source of supplying electrical loads, especially in remote and rural areas. Wind energy is one of the most commonly and rapidly growing...
Risk profile of a working plant is one of the most important topics these days. The risk profile of plant/ equipment is a kind of new method and different approach for planning and troubleshooting in the electric power industry. This paper discusses this new method of risk assessment of equipment operation in the working plants, the whole procedure is designed, developed and implemented for the equipment...
Demand for renewable energy has grown to achieve sustainable, and clean energy not associated with a carbon footprint. Photovoltaic energy (PVE) is a significant renewable resource, and this paper presents an overview of current research on PVE systems and technology. Various topologies for PV power converter/inverter technologies are reviewed, and discussed with respect to their advantages and drawbacks.
In this paper three main types of multi-level inverters are reviewed (diode-clamped, flying capacitor, and cascaded H-Bridge inverters). Different multi-level inverter topologies which are currently available on the market as far as components for the electrical integration of PV systems are also concerned. The new trends of all of these topologies are seeking to reduce the cost, the size of the inverter...
In this paper we review offshore wind energy for generating electricity at off-shore sites. In particular, we survey the impacts of offshore wind integration into the grid, various types of generators and their dynamic modeling, fault ride-through techniques used to improve generator and grid integration performance, the aggregated wind turbines modeling and finally highlight some stability and control...
