D2.1: Resilience Requirements and Objectives

D2.1 is focused on TSO expectations regarding reliability and resilience with HVDC solutions in their networks, identifying opportunities, risks, and barriers associated with HVDC, and providing initial insights into codes, standards, and regulatory framework considerations.

D3.2 Control for AC/DC Architectures

Task T3.2 aims to introduce innovative control concepts tailored to future AC/DC architectures to increase the reliability and resilience (R&R) of large-scale hybrid AC/DC systems. The proposals aim to strengthen system resilience and reliability by enhancing the grid’s ability to respond effectively to events and disturbances, focusing on both core and supplementary control layers.

D3.3: Protection Concepts

Task 3.3 of HVDC-WISE project focuses on developing guidelines for the cost-effective design of HVDC-based grid architectures’ protection systems, enabling them to withstand faults occurring on the DC side, the AC side, or within the cyber-layer.

D4.1: Identification of key technologies, potential benefits and restrictions

D4.1 outlines the building blocks and the associated technologies necessary to build a resilient and reliable AC/DC system, evaluating technology readiness levels and their relationship to system architectures, reliability, and resilience.

D4.2: Technology modelling

Power system operation and planning rely heavily on simulations and accurate models. As new equipment and configurations emerge, updated modeling and simulation approaches are essential. This report, part of the HVDC-WISE project, explores three key areas: developing models for upcoming project phases, enabling standardized HVDC equipment model exchange, and preparing converter models for dynamic phasor-based simulation.

D4.3: Library of models

This report provides a comprehensive overview of the HVDC-Wise lib, a GitHub repository containing a collection of HVDC equipment models designed to facilitate standardized model exchange.

D5.1: Scope and specifications of the tools and model needs

D5.1 presents the conceptual framework of the tools to be developed, their scope and further modelling and development needs.

D5.3: Tool for reliability and resiliency-oriented expansion planning: Release for public dissemination

D5.3 presents the second release of a decision-support tool for AC/DC grid transmission planning, developed under Task 5.2. The tool is designed to assess HVDC Grid Architectures with a focus on Reliability and Resilience (R&R) in the context of extreme weather events and long-term planning.

D5.4: Tool for Cascading Event Quantification and Operational Mitigation Strategies

This document is the final version of Deliverable 5.4 in Work Package 5 (WP5) of HVDC-WISE. It supports the project’s goal of advancing hybrid AC/DC transmission grids through reliability and resilience-oriented planning tools and HVDC-based architectures. Task 5.3 focuses on modeling, quantifying, and mitigating cascading failures using an integrated tool. The tool assesses initiating events, determines if failures propagate, measures their severity, and applies controlled islanding strategies to prevent system-wide cascades.

D6.1: Definition of the R&R oriented methodology for the use cases

Deliverable 6.1 outlines a unified methodology for resilience and reliability-oriented HVDC grid reinforcement, developed under HVDC-Wise WP6. It provides a framework for applying planning tools to use cases, integrating inputs from work packages, and assessing HVDC architectures using techno-economic reliability and resilience indicators tailored to specific grid scenarios and disturbances

CIGRE Session 2024 C1-C4 Workshop Resilience by design

The HVDC-WISE project contributed to the CIGRE Paris Session “Resilience by Design” workshop on the 27 August 2024, focused on the methods and best practices necessary to design and operate power grids that are more resilient to disruptions and can recover quickly from outages. The workshop featured a general presentation of the HVDC-WISE project, followed by a detailed discussion on the resilience aspects of HVDC systems and some specific project results.

Optimal Planning Framework for Mitigating Cyber-Induced Cascading Failures in Power Grids

As power grids become increasingly digitized, their vulnerability to cyberattacks grows—potentially triggering cascading failures. This study introduces a planning framework that simulates various cyberattack scenarios and integrates cyber-physical defenses, including optimal placement of cyber reinforcement units and energy storage, to reduce disruption, with its effectiveness demonstrated on the IEEE 39-bus system.

Assessment of the impact of HVDC systems on power system restoration

This research explores how HVDC technology can support power system restoration following major blackouts, traditionally handled by conventional generators. By integrating HVDC links and converters into restoration planning—either for power transfer or as black-start units—the study demonstrates improved recovery performance and flexibility, validated through simulations on the IEEE 39-bus system.

Cascading-aware Criticality Assessment of Transmission Corridors in IBR-dominated Systems-preprint

This study introduces a methodology to assess cascading failure vulnerability in hybrid AC/DC grids dominated by inverter-based resources (IBRs). Using dynamic simulations on a future Norther Great Britain grid model, it identifies critical transmission components and protection mechanisms that influence voltage and frequency instability, helping improve resilience planning in IBR-Heavy Systems

Improved Post-Fault Recovery in MMC-HVDC Networks using Enhanced Active Damping

This study addresses a critical challenge in HVDC systems supporting offshore wind integration: mitigating post-fault converter de-blocking oscillations, which are difficult to control due to nonlinear dynamics. It proposes an innovative control strategy combining Fuzzy Logic Control (FLC) with Proportional-Integral (PI) controllers, enhancing DC voltage regulation and stability. The approach outperforms conventional methods in reducing overshoot and improving recovery times, as validated through real-time simulations.
