Global Momentum Estimation of an Electric Power System
Angelo Maurizio Brambilla, Davide del Giudice, Daniele Linaro +1
This work presents a technique to estimate on-line the global momentum of an electric power system. It exploits the footprint of the principal frequency system dynamics. Probing to…
Definition of Static and Dynamic Load Models for Grid Studies of Electric Vehicles Connected to Fast Charging Stations
Davide del Giudice, Angelo Maurizio Brambilla, Federico Bizzarri +2
The growing deployment of electric mobility calls for power system analyses to investigate to what extent the simultaneous charging of electric vehicles leads to degraded network o…
On the Calculation of the Variance of Algebraic Variables in Power System Dynamic Models with Stochastic Processes
Muhammad Adeen, Federico Bizzarri, Davide del Giudice +4
This letter presents a technique to calculate the variance of algebraic variables of power system models represented as a set of stochastic differential-algebraic equations. The te…
Inertia Estimation Through Covariance Matrix
Federico Bizzarri, Davide del Giudice, Samuele Grillo +3
This work presents a technique to estimate on-line the inertia of a power system based on ambient measurements. The proposed technique utilizes the covariance matrix of these measu…
Effects of Inertia, Load Damping and Dead-Bands on Frequency Histograms and Frequency Control of Power Systems
Davide del Giudice, Angelo Brambilla, Samuele Grillo +1
The increasing penetration of renewable energy sources has been leading to the progressive phase-out of synchronous generators, which constitute the main source of frequency stabil…
Noise Weighting in the Design of ΔΣ Modulators (with a Psychoacoustic Coder as an Example)
Sergio Callegari, Federico Bizzarri
A design flow for ΔΣ modulators is illustrated, allowing quantization noise to be shaped according to an arbitrary weighting profile. Being based on FIR NTFs, possibly with high or…
Should ΔΣ Modulators Used in AC Motor Drives be Adapted to the Mechanical Load of the Motor?
Sergio Callegari, Federico Bizzarri
We consider the use of ΔΣ modulators in ac motor drives, focusing on the many additional degrees of freedom that this option offers over Pulse Width Modulation (PWM). Following som…
Output Filter Aware Optimization of the Noise Shaping Properties of ΔΣ Modulators via Semi-Definite Programming
Sergio Callegari, Federico Bizzarri
The Noise Transfer Function (NTF) of ΔΣ modulators is typically designed after the features of the input signal. We suggest that in many applications, and notably those involving D…
Harmonic analysis of oscillators through standard numerical continuation tools
Federico Bizzarri, Daniele Linaro, Bart Oldeman +1
In this paper, we describe a numerical continuation method that enables harmonic analysis of nonlinear periodic oscillators. This method is formulated as a boundary value problem t…
