The Benefits of Innovative Grid Technologies

Consentec published this study on how innovative grid technologies can reduce network congestion and contribute to Europe’s Fit for 55 targets. The study and the related scenario show that the combination of Dynamic Line Rating, Modular SSSC and Superconductors reduces the congestion and redispatch costs by more than 90% and the congestion-related curtailment of renewables infeed by 3 TWh in 2030

Unlocking the Queue with Grid-Enhancing Technologies

Unlocking the Queue with Grid-Enhancing Technologies

The Brattle Group quantified the impact that three Grid-Enhancing Technologies (GETs) can have on the grid. In Kansas and Oklahoma alone, these technologies can make room for 5,200 MW of wind and solar generation currently looking to connect before 2025. This is more than double the development possible without these technologies.

Modular Power Flow Control Enhancing German Transmission Grid Capacity: An Investigation

Modular Power Flow Control Enhancing German Transmission Grid Capacity: An Investigation

The German Network Development Plan includes several PSTs in the next few years. Since many network expansion efforts face delays, these projects are designed to help TSOs ‘buy time’ and increase transfer capacity by maximizing the use of the existing grid.

The Institute of Power Systems and Power Economics (IAEW) at RWTH Aachen University conducted a study to explore the system impacts of replacing four of these PSTs with m-SSSCs (modular static synchronous series compensators). The study found that compared to PSTs with the same capacity, m-SSSCs could provide double the system benefit. These benefits were possible because of the modularity and flexibility of the m-SSSCs. These characteristics allow TSOs to install the solution quickly, scale the deployments, reduce substation space and relocate the devices as necessary, ultimately allowing TSOs to better manage uncertainty compared with PSTs.

An Efficient Algorithm for Dispatch of Modular FACTS devices in Transmission Planning

An Efficient Algorithm for Dispatch of Modular FACTS devices in Transmission Planning               

This paper develops an efficient method to optimally dispatch multiple variable-impedance power flow control deployments to resolve post-contingency overloads from a planning perspective. The dispatch method is based on a PTDF DC power flow formulation and illustrated on the IEEE 39-bus test system solving with full AC power flow assumptions.

Use of Power Flow Controllers to Enhance Transmission Network Utilisation on the Irish Transmission Network

Use of Power Flow Controllers to Enhance Transmission Network Utilisation on the Irish Transmission Network

EirGrid, the Transmission System Operator in Ireland, evaluated planning options to maximize utilization of the existing network. EirGrid created a new grid development strategy which places particular emphasis on identifying technologies that can help resolve network issues. This paper presents the study findings for the application of power flow controllers to relieve system constraints.

Trends in Transmission Planning Uncertainty and the Impacts and Value of Leveraging Flexible Investment Strategies and Technologies

Trends in Transmission Planning Uncertainty and the Impacts and Value of Leveraging Flexible Investment Strategies and Technologies

This paper proposes a scorecard that was developed via input and review from dozens of utilities across the globe. It contains monetized and non-monetized metrics that represent best practices from throughout the industry. This tool offers a way for utilities to compare flexible solutions against traditional options, evaluate transmission investment decisions and improve their decision making process.

On Developing Automated Tools for Reliability Planning

On Developing Automated Tools for Reliability Planning

This paper describes the process of developing automated tools for transmission planning to address the challenge of uncertainty and leverage the ability of new, heterogeneous smart grid technology to overcome these challenges. The development process is illustrated with a simple case study of a tool to cluster thermal overload projects across a CAISO study area.
