Technical, Regulatory and Economic Development for Distributed Flexible AC Transmission Systems – D-FACTS

Technical, Regulatory and Economic Development for Distributed Flexible AC Transmission Systems – D-FACTS

This paper assesses the adoption of M-FACTS solutions (also referred to as DFACTS due to its distributed nature) from a technical, regulatory, and economic nature. This document covers the cost/benefit analysis and the regulatory point of view of DFACTS to explore the feasibility of applications in electrical power systems, starting from a perspectivewhere a wide variety of characteristics are analyzed. The intention is to favor the conception of a possible large-scale deployment of DFACTS in transmission systems, with innovative solutions to network restrictions and other relevant problems.

Development of Innovative Power Flow Controller-compatible RTCA Decision Support Tools for Enhancing Control Centre Operations

Development of Innovative Power Flow Controller-compatible RTCA Decision Support Tools for Enhancing Control Centre Operations

This paper describes the development of a decision support tool that will allow for coordinated control anddispatch of several PFC devices. The development of this tool constitutes significant advancements in two main areas:Situational Awareness and PFC Optimization. With faster and wider adoption of PFC technology, advanced real-timedecision support tools are able to assist in higher power system situational awareness and control. Together, this willresult in more robust, reliable, and resilient transmission system operation.

Real time dynamic performance, control interaction and protection studies of modular static synchronous series compensation technology in the Great Britain Transmission System

Real time dynamic performance, control interaction and protection studies of modular static synchronous series compensation technology in the Great Britain Transmission System

This paper presents the results of an in-depth system integration analysis of M-SSSC technology commissioned in the GB transmission system to provide real-time power flow control. National Grid Electricity Transmission (NGET) conducted detailed electro-magnetic transient (EMT) studies, as well as real time tests in a Control-Hardware-in-the-Loop (CHIL)configuration,to demonstrate the dynamic behavior of M-SSSCs under different operating scenarios and network configurations.

First Modular Static Synchronous Series Compensation Installation in Latin America-From Planning to Operation

First Modular Static Synchronous Series Compensation Installation in Latin America-From Planning to Operation

This paper shows the planning process to eliminate the overloads found in the Valle de Aburrá region expansion plan in Medellín, Colombia, the planning process, and the successful results of the pilot project of the firstD-FACTS installation in Latin America. In this project, it was possible to verify the operational reliability, performance, flexibility, and potential of D-FACTS on existing infrastructure.

Delivery of Modular Static Synchronous Series Compensators on the Greek transmission system to provide substantial increase in cross-border interconnection capacity

Delivery of Modular Static Synchronous Series Compensators on the Greek transmission system to provide substantial increase in cross-border interconnection capacity

This paper explores the planning and deployment of M-SSSC devices on the Greek transmission network. The whole design, preparation, and installation of the M-SSSC system was completed within one year, proving the rapid deployability of this technology. Its modular nature provided the possibility to be sized optimally for the exact system’sneeds, lowering the costs and environmental footprint of the solution by minimizing unnecessary use of equipment and space.

SSR Implication Assessment Using Modular FACTS

SSR Implication Assessment Using Modular FACTS

The increase of distributed, non-conventional generation requires fast installation and low-cost solutions that improve power systems’ flexibility and reliability. Such a solution is series compensation of transmission lines. Despite its numerous benefits, this solution raises concerns related to Subsynchronous Resonance (SSR). Flexible AC Transmission Systems (FACTS) devices constitute an improved alternative compared to traditional series compensation solutions

Modular Static Synchronous Series Compensator Offering Improved Scalability and Replicability Properties

Modular Static Synchronous Series Compensator Offering Improved Scalability and Replicability Properties

The increasing share of renewable energy generation as well as the liberalization of the electricity markets has led to transmission congestion issues. Traditionally, congestion issues were dealt through grid expansion or upgrading existing transmission lines; these solutions, however, require significant lead time, large upfront investment costs and may be subject to environmental issues or societal opposition.
