Research on the Dynamic Characteristics of Microgrid with Pulesd Nonlinear Load

With the fast development of information and electronic technology, the digitized equipments are widely used in the troops. However, the power characteristic of the digitized equipment presents the pulsed state, named pulsed loads. There are typical characteristics of pulsed loads, e.g., the peak value of power is large but the mean value is small. Hence, the influence of pulsed load on power system is different from the common loads. Microgirds are becoming a realistic scenario in which distributed energy resources, energy storage systems and power loads can be connected and integrated into grid. In view of complementary features between the renewable resources of wind energy and solar energy, the most common structure of microgrids is wind-PV-diesel-battery power generation systems. This paper presents the influence of pulsed load on the wind-PV-diesel-battery microgrid with the process of analysis, modeling and experiments. Transient characteristics of microgrid with pulesd load are analyzed in this paper.
