The research documented in this paper investigates the underlying attributes, mechanisms, advantages and disadvantages of long-distance power transmission by analysing a set of case studies based on a simple simulated system created in the PowerWorld software package. In particular, the factors that have an impact on a series of power flow variables, including active power, reactive power, magnitude...
With the annual capacity growth of wind power integration, the stochastic wind power makes it increasingly difficult to optimize traditional unit commitment with fixed load and wind power percentage. Considering load and wind powder uncertainty, the multiple scenario model of load and wind power was established using scenario reduction techniques. To explore effect of load and wind power uncertainty,...
Currently the development of large scale electric vehicles have become governments' focus of attention. Based on the research of charging and discharging power models, the paper puts forward the island formation strategy and establishes the distribution system reliability model with the electric vehicles. The Monte Carlo time sequential simulation is used to evaluate the effects of different vehicle...
In view of the declined comprehensive qualities of undergraduates of science and engineering, this paper discusses the cultivation of comprehensive qualities of undergraduates of science and engineering from the perspectives of psychological quality, communication skills, innovation ability and ability to practice and work. It also discusses the role of structural design competition in the comprehensive...
A miniature dual-mode microstrip bandpass filter by using novel dual-mode hexagonal open-loop resonators with an E-shaped stub loading is proposed in this work. The loading E-shaped stub perturbs and reduces the high-order mode frequency of the single-mode (operated) hexagonal open-loop resonator, consequently, changing the second-mode frequency of the single-mode resonator into the second operating...
In a cognitive radio network (CRN), instead of direct leaving, an interrupted secondary user (SU) is suspended to wait for another channel. The policy for the packets generated by the SU during the suspending time can be either discarding or buffering. This paper mainly analyzes the performance of a CRN against these two policies. Here, two Markov models are proposed to derive the formulas for packet...
Based on the "quasi tri-prism" model and the improved borehole data recording approach, this paper presents a method of "dummy borehole chain" to control the complicated geo-body modeling. An algorithm was designed to identify the fold, the lens body, the pinch and the fault automatically. The proposed "window densification" in this paper was used to handle the TIN densification...
