Stability Enhancement of LCL-Type Grid-Following Inverters Using Capacitor Voltage Active Damping

no code implementations8 Apr 2024 Naser Souri, Ali Mehrizi-Sani, Kambiz Tehrani

However, a derivative term appears in the active damping loop, which introduces high-frequency noise into the system.

Detection and Mitigation of Cyberattacks on Volt-Var Control

no code implementations3 Apr 2024 Milad Beikbabaei, Ali Mehrizi-Sani

Cyberattacks are becoming more frequent, and attackers can use different mechanisms, such as denial of service (DoS) and false data injection (FDI).

Scalable Optimal Design of Incremental Volt/VAR Control using Deep Neural Networks

no code implementations4 Jan 2023 Sarthak Gupta, Ali Mehrizi-Sani, Spyros Chatzivasileiadis, Vassilis Kekatos

According to non-incremental control rules, such as the one mandated by the IEEE Standard 1547, the reactive power setpoint of each DER is computed as a piecewise-linear curve of the local voltage.

Reinforcement Learning$\unicode{x2013}$Based Transient Response Shaping for Microgrids

no code implementations11 Jul 2022 Ashwin Venkataramanan, Ali Mehrizi-Sani

This work explores the usage of a supplementary controller for improving the transient performance of inverter$\unicode{x2013}$based resources (IBR) in microgrids.

Integrated Fault Diagnosis and Control Design for DER Inverters using Machine Learning Methods

no code implementations21 Feb 2022 Forouzan Fallah, Amin Ramezani, Ali Mehrizi-Sani

This paper employs a supervised machine learning (ML) algorithm to propose an integrated fault detection and diagnosis (FDD) and fault-tolerant control (FTC) strategy to detect, diagnose, and classify the grid faults and correct the input voltage before affecting the grid-connected distributed energy resources (DER) inverters.
