The allure of integrating wind power, as a clean renewable energy source, into distribution grids is usually blurred with its undesirable impacts. These include reverse power flow, voltage rise, and disruption of the normal operation of voltage/VAr (VVAr) control devices. This paper describes a voltage control scheme that coordinates the VVAr control devices along with energy storage to mitigate integration...
An important trend in photovoltaic lines of research is the use of plug and play microinverters attached to the panel, allowing the so called AC module. However, these converters are subjected to high temperature and humidity. In order to improve reliability and achieve long lifetime, this work proposes a new topology, which provides inductive power decoupling and eliminates electrolytic and even...
Nonlinear transmission lines (NLTLs) provides an ingenuous way of generating RF without using vacuum electron tubes. For high peak power, (MW) and frequency up to several hundreds of MHz dielectric or ferrite-segmented lines (a synchronous wave NLTL) have been used. Other configuration implemented with better frequency results (from 400 MHz up to 4 GHz in C-band) is a continuous ferrite loaded coaxial...
In recent years, nonlinear transmission lines (NLTLs) have been investigated for high-power radiofrequency (RF) generation. High-power waves produced using NLTLs can be applied in mobile defense platforms and satellite communications as they can reach tens of MW of peak power. Their principle of operations is based on the nonlinearity of the lumped elements (Ls and/or Cs) used in these lines. In this...
Intermittency of variable renewable generation (VRG) requires time sequence analysis, over a defined interval, to adequately capture VRG characteristics. As the penetration level rises, connected VRGs inject as much energy as the existing resource permits. It is therefore, essential to develop a technique that maintains system voltage profile, and facilitates the smoother integration of VRGs into...
A nonlinear lumped element transmission line (NLETL) that comprises a LC-ladder network where either the capacitors or inductors are nonlinear can be used to convert an input rectangular pulse to a series of RF pulses at the output. This article describes the implementation and demonstration of a high voltage nonlinear hybrid line (NLHL) where both the line components (inductor and capacitors) are...
An RF and mm-wave platform developed in 65 nm SOI CMOS technology is presented. The SOI FET performance in a wired cell is measured up to fT=300 GHz and 200 GHz for NFET and PFET. Ring oscillator records 3.6 psec minimum inverter stage delay. Back-end-of-line vertical native capacitor (VNCAP) and on-chip inductor performances are reported. The performance scaling trends of mmWave PLL front-end components...
This letter presents symmetric vertical parallel plate (VPP) capacitors in 65-nm silicon-on-insulator CMOS technology. Three VPP capacitors with different metal layer options are examined with respect to effective capacitance density and -factor. An effective capacitance of 2.18 and a -factor of 23.2 at 1 GHz are obtained from a 1x + 2x (M1-M6) metal layer configuration's pre-de-embedding measurement...
