The Benefits of Innovative Grid Technologies

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.

Making the most of Europe’s grids: grid optimisation technologies to build a greener Europe

Making the most of Europe’s grids: grid optimisation technologies to build a greener Europe

WindEurope’s position paper explains that while grid expansion is crucial and needs to accelerate, grid optimization and timely solutions must also be considered. Grid optimization technologies can maximize the use of transmission capacity by increasing thermal and/or system limits or optimally addressing conservatively set margins. This can mitigate renewables variability, accelerate their integration and minimize their curtailment. The paper includes an assessment of grid optimization technologies, a variety of case studies and recommendations for regulatory changes to incentize large-scale adoption of 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.

Improving Transmission Operation with Advanced Technologies: A Review of Deployment Experience and Analysis of Incentives

Improving Transmission Operation with Advanced Technologies: A Review of Deployment Experience and Analysis of Incentives                        

The Brattle Group and Grid Strategies LLC jointly produced a report discussing the benefits of grid enhancing technologies to the transmission system. These technologies can provide economic benefits worth hundreds of millions of dollars and cost much less than conventional transmission upgrades. However, the existing regulatory structure in the US lacks sufficient incentive for utilities to capture the value these technologies can provide to the overall system. Hence, a modified regulatory framework that ensures the greatest societal benefit is worth considering.

An application of modular FACTS devices to relieve transmission constraints and accelerate wind farm connections and firm access

An application of modular FACTS devices to relieve transmission constraints and accelerate wind farm connections and firm access                                      

This paper explains how modular power flow control can be used to quickly create additional capacity in ways not previously deemed cost effective or possible. This technology can alleviate grid constraints that limit renewable generation on the transmission and distribution grids.
