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.

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.

Increasing Bulk Power Transfer of Renewable Generation with Modular FACTS to Lower Wholesale Costs to Consumers

Increasing Bulk Power Transfer of Renewable Generation with Modular FACTS to Lower Wholesale Costs to Consumers

This paper describes how three Australian network owners, TransGrid, AusNet and ElectraNet, plan to leverage modular FACTS to facilitate the bulk transfer of renewable energy across regional boundaries. Using modular FACTS to improve the utilization of existing networks means reduced of wind generation curtailment, improved market access for hydro generation, and a lower probability of unserved energy following retirement of fossil fuel generators.

Using Modular Flow Control to Improve Transfer Capability, Reduce Constraints on Renewable Generation and Alleviate Congestion

Using Modular Flow Control to Improve Transfer Capability, Reduce Constraints on Renewable Generation and Alleviate Congestion

ElectraNet, the Transmission Operator in South Australia, describes an economic application of modular power flow control devices to alleviate congestion on transmission lines, improving the power transfer capability of transmission corridors by increasing their average utilization. The analysis considers the capital cost of equipment against fuel cost-savings achieved by displacing gas-fired generation with renewable generation sources.
