Abstract This paper considers a parallel queueing model with two servers, where arriving customers join the shortest queue. In [14], we studied a similar queueing model, and obtained the tail decay rate of the stationary distribution by using the matrix analytic approach. The main objectives of this paper are to extend the result in [14] to a more general model, and to clarify difficulty when w...

As the wind power penetration increases, short-term prediction accuracy of is great importance for safe and cost-effective operation grid in which integrated. Traditional farm uses numerical weather (NWP) information as an important input but does not consider correlation characteristics NWP from different farms. In this study, a convolutional neural network–long memory based model clusters pro...

The existing research on the distribution characteristics of displacement and acceleration transformer axial vibration under short-circuit conditions is based ignoring damping parameters. An accurate description windings, especially for winding conditions, has a poor effect. In this paper, damping, stiffness, mass parameters between windings are comprehensively considered, classical “mass-sprin...

The integration of Distributed Energy Resources (DER) in the distribution network has plenty of advantages if their allocation and Penetration Level (PL) are done appropriately. Hence, the challenge of finding the best allocation and PL of DERs in large distribution networks is an important but intricate problem. This paper proposes a novel methodology to simultaneously determine the optimal lo...

In this paper, considering optical feedback as an optical injection, and taking in to account round-trip time role in the external cavity, a standard small signal analysis is applied on laser rate equations. By considering the relaxation oscillation (f2) and external cavity frequencies (f) ratio for semiconductor laser, field amplitude response gain, optical phase and carrier number for long ex...
