The solar power system has been widely developed due to its environmental friendliness and sustainability. Normally, PV panels would be preferable to set up on rooftop of building or free-standing in unsheltered areas. Therefore, the negative impacts on these systems from bad weather conditions, like storms and lightning, have been evident. Vietnam is located in the region of tropical monsoon weather, especially one of the three strongest thunderstorm areas in the world. And the overvoltage by lightning transient currents on a PV system not only could fault, damage to electrical/electronic equipments, but also effect adversely on the human health and economic. In this paper, our team has chosen the lightning strokes of single-peaked current forms and has simulated it under the equivalent engineering models by Matlab-Simulink. The obtained results allowed the analysis of overvoltage scenarios in grid-tied solar power system in Vietnam and the assessment of the surge protective device activities of Metal Oxide Varistors during overvoltage. ]]>

Drying in f ruit is a solution for fruit preservation and inhibits the growth of bacteria, yeasts, and mold through the removal of water. And with the complexity of the composition chemical (sugars, proteins, lipids, minerals, vitamins, flavors, etc.), the fruits need to be observed and controlled during drying to have positive effects and avoid negative impacts on the final product. ]]>
