Practical Framework for Power System Strength
Ignacio Ponce, Federico Milano
A novel analytical framework for power system strength was recently introduced in the IEEE Transactions on Power Systems, providing a unified formulation for assessing voltage and…
Analytical Framework for Power System Strength
Ignacio Ponce, Federico Milano
This paper proposes a general framework to evaluate power system strength. The formulation features twelve indicators, grouped in three dynamical orders, that quantify the resistan…
Teager Energy Operator as a Metric to Evaluate Local Synchronization of Power System Devices
Bruno Pinheiro, Ignacio Ponce, Daniel Dotta +1
This paper introduces a novel formulation to evaluate the local synchronization of power system devices, namely Synchronization Energy (SE). The formulation is derived based on the…
Synthetic Discrete Inertia
A. Vaca, F. Milano
This letter demonstrates how synthetic inertia can be obtained with the control of flexible discrete devices to keep the power balance of power systems, even if the system does not…
Equivalence between Geometric Frequency and Lagrange Derivative
Federico Milano
The paper shows the equivalence between the geometric frequency of an electric quantity, namely, voltage and current, and the Lagrange derivative of a stream-line of a fluid. The g…
Dual Grid-Forming Converter
Federico Milano
This letter proposes a dual model for grid-forming (GFM) controlled converters. The model is inspired from the observation that the structures of the active and reactive power equa…
Local Synchronization of Power System Devices
Ignacio Ponce, Federico Milano
This paper introduces a novel concept of local synchronization of power systems devices based on the difference between the complex frequency of the voltage and current injected at…
Dynamic Slack Bus
Federico Milano
This letter proposes a general dynamic formulation of slack bus. With this aim, the angle constraint imposed by the slack bus is redefined as a set of differential equations and an…
Modeling Hybrid AC/DC Power Systems with the Complex Frequency Concept
Ignacio Ponce, Federico Milano
The concept of complex frequency has been recently introduced on the IEEE Transactions on Power Systems to study bus voltage variations in magnitude and frequency and their link wi…
