This study quantifies the benefits of three Grid-Enhancing Technologies (GETs): dynamic line rating, advanced power flow control and topology optimization. The study demonstrates that these GETs could be deployed on Kansas' and Oklahoma's grids to integrate 5,200 MW of wind and solar generation currently in interconnection queues by 2025, more than double the development possible without the technologies. The study results yielded over $175M USD in savings, and 3MT of CO2 emissions avoided. On a national scale, the results of the study suggest significant economic, environmental, and policy-related implications.

The growth in demand, the high penetration of small, distributed generation plants, and the increasing changes in power flow patterns typical of deregulated schemes are commonly the drivers for overloads in transmission system assets. 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 first D-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. The study also emphasizes the social, environmental, and technical benefits the technology provides, including better rates for end-use customers. The authors compile lessons learned to encourage the incorporation of D-FACTS technology into the Colombian National Interconnected System (SIN).

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. In addition, a comprehensive set of Protection-In-The-Loop (PIL) studies were conducted using a real-time simulation platform to investigate the impact of M-SSSCs on existing distance protection schemes. The results of the EMT study analysis demonstrate the effects of series compensation devices on network power flows and confirm no adverse impacts on system integration. The PIL studies ascertain the value of the fast-acting bypass and demonstrate that the systems-level risks of affecting the operation of the existing distance protection scheme is low. This research contributed to: the improvement of M-SSSC controls and performance, ensured NGET technical specification compliance, and increased the confidence of the National Grid's engineers about the capability of this technology to provide boundary transfer increases without adding risk.

Transmission line monitoring and power flow control in meshed networks have become major concerns for TSOs due to the heavily stressed electrical power systems caused by increased renewable energy penetration. Modular Synchronous Series Compensation (M-SSSC) technology can provide scalable, cost-effective solutions to network congestion issues by providing enhanced network operability and control. 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’s needs, lowering the costs and environmental footprint of the solution by minimizing unnecessary use of equipment and space. Power flow studies and the analysis of real site test results validate the ability of M-SSSC to control power flows in real-time and deliver positive impacts on existing and forecast cross-border transfer capacity. This affects the grid's ability to bring renewables online, reduce network congestion, maximize cross-border infrastructure use, and ensure network security.

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 perspective where 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.

Key operational challenges are on the horizon for transmission systems, grid congestion and energy security. One emerging network solution is Power Flow Control (PFC) technology. One key challenge for PFC technology Is developing centralized methods for the coordination of many distributed PFC solutions--an offering not yet widely available. This paper describes the development of a decision support tool that will allow for coordinated control and dispatch 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-time decision support tools are able to assist in higher power system situational awareness and control. Together, this will result in more robust, reliable, and resilient transmission system operation.
