We study the asymptotic expansion of transmission eigenvalues for anisotropic thin layers. establish a rigorous second-order simple with respect to thickness layer. The convergence analysis is based on generalization Osborn's Theorem non-linear eigenvalue problems by Moskow [Nonlinear approximation compact operators. J Math Phys. 2015;56(11):113512]. also provide formal derivation in more gener...

Transmission expansion planning (TEP), the determination of new transmission lines to be added an existing power network, is a key element in system planning. Using classical optimization define most suitable reinforcements desirable alternative. However, extent under-study problems growing, because uncertainties introduced by renewable generation or electric vehicles (EVs) and larger sizes und...

The increased deployment of distributed generation calls for the coordination and interaction between transmission distribution levels. This requirement is particularly relevant planning purposes when renewable-based involved. Unfortunately, in current industry practice, network planners solve their problems independent each other, thereby leading to suboptimal solutions. Within this context, p...
