[Show abstract] [Hide abstract]
ABSTRACT: Dcdc converter control has major role in solar or photovoltaic (PV) systems with maximum power point tracking (MPPT). In this paper, analysis of multiphase boost converter for PV battery charging system is presented. Mathematical modeling of PV array and three phase boost converter is described and the simulation results are presented for 4.8kW PV array based battery charging system. Input voltage of the boost converter is controlled to regulate the maximum power point of the PV array. Input voltage control provides the advantage of easy functioning of MPPT algorithm. With the use of multiphase topology for the converter, the stress on power semiconductor switches reduces and additional benefit of reduced ripple current on PV array is obtained. Incremental conductance algorithm is chosen for the tracking of maximum power point (MPP).IEEE SCEECS 2014; 03/2014  [Show abstract] [Hide abstract]
ABSTRACT: Design and utilization of a Virtual Photovoltaic Systems Laboratory for undergraduate curriculum are introduced in this paper. The laboratory introduced in this study is developed to teach students the basics and design steps of photovoltaic solar energy systems in a virtual environment before entering the field. The users of the proposed virtual lab will be able to determine the sizing by selecting related parameters of the photovoltaic system to meet DC and AC loading conditions. Besides, the user will be able to analyze the effect of changing solar irradiation and temperature levels on the operating characteristics of the photovoltaic systems. Common DC bus concept and AC loading conditions are also included in the system by utilizing a permanent magnet DC motor and an RLC load as DC and AC loading examples, respectively. The proposed Virtual Photovoltaic Systems Laboratory is developed in Matlab/Simulink GUI environment. The proposed virtual lab has been used in Power Systems Lab in the Department of Electrical and Electronics Engineering at Karadeniz Technical University as a part of undergraduate curriculum. A survey on the students who took the lab has been carried out and responses are included in this paper.International Journal of Photoenergy 03/2014; 2014:17. · 2.66 Impact Factor  [Show abstract] [Hide abstract]
ABSTRACT: Yemen is one of the least developed countries in the Middle East. Since more than 23 years, Republic of Yemen is going from darkness to darkness in the field of electricity power sector. It is considered as one of chronic problem in the country since 1990 up to now. The next 10 years Yemen meets a huge and serious problem in electrical power sector more than ever. Renewable Energy is considered as one of optimal solutions for power sector in Yemen which is called Solar, Wind and Geothermal energies. The objective of this work is to study and analyse existing status of power sector in Yemen and introduce the advantages of renewable energy resources. In depth study about solar and wind energy is presented in this paper. Renewable energy could enhance electrical grid system in Yemen and generate the green energy for Yemeni rural areas to serve: education sector, lightening homes, and medical clinics, etc. The importance of this paper is to illustrate the features of clean energy to enhance the power sector in Yemen and propose solutions to develop this sector. Keywords Clean energy, Yemeni power sector, solar irradiation, solar and wind energies, electrification of rural areas, reduce the pollution.INTERNATIONAL JOURNAL of RENEWABLE ENERGY RESEARCH. 10/2013; IJRER(3):4.
