System imbalance due to power fluctuation is the first concern of power grid with large scale wind power integration. Traditional studies are limited in time domain, where the modeling is not convenient enough. In this paper, a model based on frequency domain is proposed. This model is more precise, and capable to take some important factors, such as the layout of wind farm, into account. This paper...
The adaptability of a fuel cell system to unstable peripheral environment is a crucial criterion to evaluate its performance. During actual operation, changes in the temperature of the fuel cell stack and ambient air condition will probably impair the speed and accuracy of the system power response. Therefore, in this paper, we designed corresponding control units for the air supply system - a current...
The flow increasing of civil aviation requires reducing the separation minima to improve the usability of the airspace, and then we attempt to evaluate the safety of the reduced separation minima so as to ensure the flight safety. This article includes a detailed analysis of the collision risk on the parallel route and intersecting route, and emphasizes on building the united collision risk model...
