Due to the randomicity of wind power energy, the voltage flicker of power grid will occur after large-scale wind power is connected with power grid. The factors such as wind regime, characteristics of wind power generators and system condition of power gird impact the voltage flicker caused by wind power generation. Based on the IEC(International Electrotechnical Commission) Standard, this paper analyzes...
The BP network has the disadvantages such as low learning efficiency, low speed of convergence, easily falling into the local minimum state, poor ability to adapt, ect. For PSO algorithm, it is fast for convergence, especially at the initial stage, simple for the computing, and is easy to implement. Compared with the genetic algorithms, it does have not the complex operations of hybrid codecs, mutation,...
Grid is attracting more and more attentions by its massive computational capacity. Tools like Globus Toolkit and MPICH-G2 have been developed to help scientists to facilitate their researches. As a Grid-enabled implementation of MPI, MPICH-G2 helps developers to port parallel applications to cross-domain environment. Since the current computationally-intensive parallel applications, especially long-running...
