IEEE Std. 1584 specifies that capacitors must be part of the arc-flash study. The software tools generally adopted for analytical studies are not suitable for the calculation of the arc-fault incident energy in the presence of capacitor banks. The reason for this deficiency is that the model of the electrical network is only valid for the analysis of short circuit currents at the fundamental frequency...
Supplying electrical energy to the load on demand, economically and with acceptable levels of reliability and service quality is the main task of a distribution system. Energy distribution reliability is important in the competition conditions in electricity markets because consumers directly supply energy. Therefore, it is not enough to estimate how reliable the distribution system is at present...
This paper evaluates the impact of local government capital investment subsidies for the installation and the price of rooftop solar photovoltaic (PV) system in Japan. By creating the micro-level unique panel dataset covering the period between 2009 and 2014, we compared municipalities that employed subsidies with municipalities that did not to analyze their effects on the amount of installation and...
The increasing trend of people moving to urban areas and the associated urbanization process require facing challenges regarding city infrastructures capability to cover citizens needs for energy, water, transportation, healthcare. education, safety. The smart urban technologies represent an important contribution to the sustainable development of cities, making smart cities a reality. The concept...
In the present work, a 2D numerical study, using the k-ε Standard and k-ε EARSM turbulence models, has been carried out to determine which turbulence model better predicts the performance of the experimental Darrieus turbine test model. The computational fluid dynamics (CFD) was done for a vertical water Darrieus turbine (VAHT), with three NACA0020 straight blades, rotating at five different RPM (96,...
In the face of energy crisis and environmental pollution problems, all the countries in the world vigorously promote the development of electric vehicles. Electric vehicle charging infrastructure is the necessary infrastructure to the development of electric vehicles. This work has been focused on Electric Vehicles' Charging Stations (CSs) deployment. It has been considered in this study several constraints...
