Because wind is an intermittent power source, the variability may have significant impacts on system operation. Some studies have shown that this impact on regulation is not significant, but the impact on load following requirements has not yet received much attention. Part of the difficulty of analyzing the load following impact of wind is the inadequacy of most modeling frameworks to accurate...

This paper provides a new approach for power flow and modeling analysis of three phase unbalanced radial distribution systems (URDS) using the simple forward/backward sweep-based algorithm. A three phase load flow solution is proposed considering voltage regulator and transformer with detailed load modeling, for the transformer modeling symmetrical components theory is used and zero sequence-vo...

The DNS relies on caching to ensure high scalability and good performance. In optimizing caching, TTL adjustment provides a means of balancing between query load and TTLdependent performances such as data consistency, load balancing, migration time, etc. To gain the desired balance, TTL adjustment depends on predictions of query loads under alternative TTLs. This paper proposes a model of DNS s...

Modeling epistasis in genomic selection is impeded by a high computational load. The extended genomic best linear unbiased prediction (EG-BLUP) with an epistatic relationship matrix and the reproducing kernel Hilbert space regression (RKHS) are two attractive approaches that reduce the computational load. In this study, we proved the equivalence of EG-BLUP and genomic selection approaches, expl...

in this paper, a two-surfaces sliding mode controller (tssmc) is proposed for the voltage tracking control of a two input dc-dc converter in application of electric vehicles (evs). the imperialist competitive algorithm (ica) is used for tuning tssmc parameters. the proposed controller significantly improves the transient response and disturbance rejection of the two input converters while prese...

In this study, the validity of the approximation used in the modeling of resonant inverter tuning loop is discussed. With this approach, the phase-frequency relation of a resonant load around load resonant frequency can be expressed as a linear function for a reasonably high quality factor load. Results are verified by simulations.

This paper presents equivalent models of Modular Marx Multilevel Converter Diode (MCD) plus load, for bipolar or unipolar operation. With these models, it’s possible to analyze and understand the dynamic behavior of the pulse output voltage and current at the load. Simulation and experimental results, for different voltage levels, and various types of load are presented. Keywords-Modeling , Mul...
