A Novel Collapse Prediction Index for Voltage Stability Analysis and Contingency Ranking in Power Systems
Voltage instability is a serious phenomenon that can occur in a power system because of critical or stressed conditions. To prevent voltage collapse caused by such instability, accurate voltage collapse prediction is necessary for power system planning and operation. This paper proposes a novel collapse prediction index (NCPI) to assess the voltage stability conditions of the power system and the critical conditions of lines. The effectiveness and applicability of the proposed index are investi

Dual Fuzzy-Sugeno Method to Enhance Power Quality Performance Using a Single-Phase Dual UPQC-Dual PV Without DC-Link Capacitor
This paper proposes a novel configuration of a dual UPQC supplied by a dual photovoltaic (PV), hereinafter referred to as 2UPQC-2PV,to improve the power quality performance of a single-phase 220 V/50 Hz distribution system. The 2UPQC-2PV configuration is proposed to anticipate the possible failure of both inverters in one of the UPQC circuits. The PV array replaces the DC-link capacitor to maintain its voltage connected to the DC-link of the UPQC constant while at the same time supplying active

SEKV-E: Parameter Extractor of Simplified EKV I-V Model for Low-Power Analog Circuits
This paper presents the open-source Python-based parameter extractor (SEKV-E) for the simplified EKV (sEKV) model, which enables the modern low-power circuit designs with the inversion coefficient design methodology. The tool extracts the essential sEKV parameters automatically from the given I - V curves using the direct extraction and the multi-stage optimization process. It also handles the overfitting issue because of non-linear least squares. Moreover, this work demonstrates t

A Low-Noise High-Gain Broadband Transformer-Based Inverter-Based Transimpedance Amplifier
In this paper, a transformer-based bandwidth (BW) extension technique is employed to improve the BW, noise, and silicon area of inverter-based transimpedance amplifiers (TIAs) even when they use inductive peaking. A TIA based on the proposed technique, designed and laid out in a 16-nm FinFET process, demonstrates a 36% increased in BW, a 19% reduction in input-referred noise, and a 57% reduction in silicon area compared to the conventional TIA with inductive peaking. In the proposed TIA architec
