A new reactive power optimization model involved the probability of voltage violation (PVV) and power losses to resolve the stochastic impact of wind power injection on voltage regulation. The derivation of PVV is given and applied to a variable-speed constant-frequency (VSCF) wind turbine firstly which is calculated by combining the probability of wind farm power output and the relationship between...
A new algorithm of blind signal separation that jointly exploits the selection of rational nonlinear functions and relative Newton method is proposed. This algorithm uses rational nonlinear functions in constructing the cost function, which have less computational complexity than the usual nonlinear functions. We use relative Newton method to solve the solution procedure of the cost function based...
The algorithms of Delaunay triangulation are the main algorithms when establishing DEM. The algorithm of going forward beginning with margins has been improved in two ways after some researches are made on several Delaunay triangulation algorithms. On the one hand, edges are directly used as the base when going forward, other than using Voronoi figure as the base. On the other hand, data set partition...
