When designing a maximum power point tracking （MPPT） algorithm, it is often difficult to correctly predict, before field testing, the behavior of this MPPT under varying solar irradiation on photovoltaic （PV） panels. A solution to this problem is to design a maximum power point trackers simulator of a PV system used to test MPPT algorithms. This simulator must have the same role as the MPPT card of the PV panel and thus will fully emulate the response of a real MPPT card of the PV panel. Therefore, it is a good substitute to help to test the peak power trackers of the PV system in the laboratory. This paper describes a simple peak power trackers simulator of the PV system which has a short response time thus, can be used to test MPPT algorithms under very rapid variation condition. The obtained results and the theoretical operation confirm the reliability and the superior perfor- mance of the proposed model.

Wind-diesel hybrid power system integration in the south Algeria

引用

Frontiers in Energy 2015年第3期9卷 259-271页

作者： Khaireddine ALLALI El Bahi AZZAG nabil kahoul Department of Electrical Engineering Badji Mokhtar University- Annaba Annaba 23000 Algeria Laboratoire d'Electrotechnique d'Annaba Badji Mokhtar University-Annaba Annaba 23000 Algeria

In most isolated sites situated in south Algeria, the diesel generators are the major source of electrical energy. Indeed, the power supply of these remote regions still poses order problems （technical, economical and ecological）. The electricity produced with the help of diesel generators is very expensive and responsible for CO2 emission. These isolated sites have significant wind energy potential. Hence, the use of twinning wind-diesel is widely recommended, especially to reduce operating deficits. The objective of this paper is to study the global modeling of a hybrid system which compounds wind turbine generator, diesel generator and storage system. This model is based on the control strategy to optimize the functioning of the hybrid system and to consolidate the gains to provide proper management of energy sources （wind, diesel, battery） depending on the load curve of the proposed site. The management is controlled by a controller which ensures the opening/closing of different power switches according to meteorological conditions （wind speed, air mass, temperature, etc）.
