Abstract

The paper presents the electric vehicle charging model with fast DC charging technology based on the mathematical modelling and theoretical studies. The problem in this study is to model the fast charging system in order to describe the control and stability of DC bus voltage. The research direction in this study is to design a novel charger in reality. A novel 200 kW fast charger was designed for modeling of fast charging system. The proposed fast charger consists of two portions such as an AC-DC converter and a DC-DC converter using dual active bridge (DAB) technique performing a charging function. The parameters of consumable devices used in the model are mentioned for performance specifications. The main section is a design of transformer that used in the DC-DC converter in order to obtain isolation between the AC system and electric vehicle. This leads to achieve the improvements in the power quality on the AC grid. The performances of the proposed fast charger system were verified through simulations results. The modeling and simulations are performed in MATLAB/SIMULINK and all results confirm the feasibility of proposed design for experimental studies. The recommendation of the system was also given based on the comparison of recent works which were met the objectives of the studies.

Abstract

Electricity is an important source of energy in everyday life. In recent decades, growing energy demand worldwide has significantly fueled energy production, leading to environmental impacts such as global warming and ozone depletion. it has also endangered the species. Hence, the whole world has started shifting towards green energy generation, eliminating all the negative impacts on the environment. Solar energy is the most CO2 emission save compared to non-renewable energy sources. A photovoltaic generator is useful in areas well exposed to the sun. This paper is aimed the total amount of energy generated by the solar system connected to the grid on the 230 kV transmission line. This result was conducted by comparing the energy generated with tilt angle of 15°,20°,25°,30°and 35°. The most energy generated is produced with 25° of tilt angle according to the simulation result in this paper. The result was simulated by using PVsyst. This paper presents energy production of a 40-MW grid connected photovoltaic system located at Minbu Township in Myanmar. The simulation is carried out in order to get maximum energy production and the incident radiation, performance ratio, energy into the grid and energy output at array and losses. Based on the simulation result, it is concluded that maximum energy production and performance ratio are 75730 MWh and 81% through the year. The CO2 emission was saved 424781.5 tons per year. The incident energy in collector plane is 5.220kWh/m2/day. This research is only conducted for analysis on existing grid connected utility scale solar PV system and not provided for advanced techniques.
