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.

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.

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.

Assessment of applicability and cost savings of deploying Smart Wires power flow controls to integrate renewable energy in PJM

Assessment of applicability and cost savings of deploying Smart Wires power flow controls to integrate renewable energy in PJM                    

DNV GL performed an economic assessment of Smart Wires power flow control technology for improving transmission capacity on existing high voltage transmission lines in the PJM market. Results show that if Smart Wires is used in conjunction with conventional transmission enhancements, transmission cost savings of nearly 50% are possible along with equal or better operational performance in terms of power prices, deliverability of renewable energy, transmission congestion and system costs.

Smart Wires – A Distributed, Low-Cost Solution for Controlling Power Flows and Monitoring Transmission Lines

Smart Wires – A Distributed, Low-Cost Solution for Controlling Power Flows and Monitoring Transmission Lines

Distributed FACTS technology allows utilities to increase power transfers in meshed networks by increasing average line utilization. It is projected to have significantly lower cost and lead time than new line construction, reconductoring, or conventional FACTS technology. This paper summarizes the prototype development and demonstrates the feasibility and impact of the technology.
