Permanent Magnet Synchronous Generator Driven Wind Energy Conversion System Based on Parallel Active Power Filter [PDF]

Journal of Electrical and Electronics Engineering, 2014
This paper proposes a novel application of the instantaneous P-Q theory in a wind energy conversion system (WECS). The proposed WECS is formed by permanent magnet synchronous generator (PMSG) wind turbine system connected to the grid through parallel ...

Two Types of Solutions to a Class of (p,q)-Laplacian Systems with Critical Sobolev Exponents in RN

Advances in Mathematical Physics, 2018
We focus on the following elliptic system with critical Sobolev exponents:  -div⁡∇up-2∇u+m(x)up-2u=λup⁎-2u+(1/η)Gu(u,v),  x∈RN; -div⁡∇vq-2∇v+n(x)vq-2v=μvq⁎-2v+(1/η)Gv(u,v),  x∈RN; u(x)>0,v(x)>0,  x∈RN, where μ,λ>0 ...

Operator Lipschitz functions on Banach spaces

, 2016
Let $X$, $Y$ be Banach spaces and let $\mathcal{L}(X,Y)$ be the space of bounded linear operators from $X$ to $Y$. We develop the theory of double operator integrals on $\mathcal{L}(X,Y)$ and apply this theory to obtain commutator estimates of the form $\

Non-relativistic limit of the Mielke–Baekler gravity theory

European Physical Journal C: Particles and Fields
In this paper, we present a generalized non-relativistic Chern–Simons gravity model in three spacetime dimensions. We first study the non-relativistic limit of the Mielke–Baekler gravity through a contraction process.

Iterative Algorithm for Solving a Class of Quaternion Matrix Equation over the Generalized (P,Q)-Reflexive Matrices

Abstract and Applied Analysis, 2013
The matrix equation ∑l=1uAlXBl+∑s=1vCsXTDs=F, which includes some frequently investigated matrix equations as its special cases, plays important roles in the system theory.

Notes on the algebraic curves in (p,q) minimal string theory

, 2006
Loop amplitudes in (p,q) minimal string theory are studied in terms of the continuum string field theory based on the free fermion realization of the KP hierarchy.

WAYS OF P-Q THEORY MODERNIZATION FOR WORK IN NON-SINUSOIDAL UNBALANCED VOLTAGE CONDITIONS

Electrical engineering & Electromechanics, 2013
Two different techniques of P-Q instantaneous power theory mathematical apparatus modernization for shunt active filters are analyzed. Both techniques are equal in nature while different in implementation.

Reciprocal non-relativistic decoupling limits of String Theory and M-Theory

Journal of High Energy Physics
It has recently been realised that there are supersymmetry-preserving non-relativistic decoupling limits associated with each half-BPS object in String Theory and M-Theory.

Resummation of boson-jet correlation at hadron colliders

Journal of High Energy Physics, 2019
We perform a precise calculation of the transverse momentum ( q → T $$ {\overrightarrow{q}}_T $$ ) distribution of the boson+jet system in boson production events.

NNLO Corrections to the Polarized Drell-Yan Coefficient Function

, 2004
We present the full next-to-next-to-leading order (NNLO) corrections to the coefficient function for the polarized cross section $d \Delta\sigma/d Q$ of the Drell-Yan process. We study the effect of these corrections on the process $p+p\to l^+l^-+`X'$ at
