This paper presents a new method named “Life cycle model” for optimal placement of Distributed Generators in a distribution network. The impact of DG at the distribution level is investigated with an emphasis on active power losses and allocation for minimizing the cost of losses and capacity investment costs simultaneously. An application of the proposed method for a distribution network is pr...

In this paper, at first the appearance background electricity grid in the rural areas of west China, and its meaning as well as the concept and structure of DG technologies are resented, and a DG technologies mode of development in the rural areas of west China is given. The development ideas and the future development direction of DG in are compared and summarized. At last, the significance of...

We compare numerically the performance of a new continuous-discontinuous finite element method (CDFEM) for linear convection-diffusion equations with three well-known upwind finite element formulations, namely with the streamline upwind Petrov-Galerkin finite element method, the residualfree bubble method and the discontinuous Galerkin finite element method. The defining feature of the CDFEM is...

Recent advances in parsing technology have made treebank parsing with discontinuous constituents possible, with parser output of competitive quality (Kallmeyer and Maier, 2010). We apply Data-Oriented Parsing (DOP) to a grammar formalism that allows for discontinuous trees (LCFRS). Decisions during parsing are conditioned on all possible fragments, resulting in improved performance. Despite the...

In this paper, we study the purely discontinuous Girsanov transforms which were discussed in Chen and Song [3] and Song [9]. We show that the transition density of any purely discontinuous Girsanov transform of a α-stable-like process, which can be nonsymmetric, is comparable to the transition density of the α-stable-like process. Running Title: Density estimates of the purely discontinuous Gir...

A technique for adaptive conjugate smoothing of discontinuous fields is presented in the paper. The described technique is applicable in various engineering problems and is especially effective when hybrid numerical – experimental methodologies are used. Adaptive image smoothing and stretching strategy is illustrated for a discontinuous plain stress field problem when photoelastic fringes repre...

The paper is devoted to the problems of an impulse control for the systems, whose dynamic is described by ordinary nonlinear differential equations. The problem of description for a discontinuous solution, arising from the using of an impulse control, is considered. The representation of the discontinuous (generalized) solutions is obtained on the basis of the method of a discontinuous time cha...

We prove the convergence of a discontinuous Galerkin method approximating the 2-D incompressible Euler equations with discontinuous initial vorticity: ω0 ∈ L2(Ω). Furthermore, when ω0 ∈ L∞(Ω), the whole sequence is shown to be strongly convergent. This is the first convergence result in numerical approximations of this general class of discontinuous flows. Some important flows such as vortex pa...
