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

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.

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.

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.
