Test Case: Modular SSSC and LCC-based HVDC Link Technical Synergies

Test Case: Modular SSSC and LCC-based HVDC Link Technical Synergies

This paper assesses the technical benefits that series FACTS (Flexible Alternating Current Transmission System) devices can provide to support the technical challenges when LCC-based HVDC links are connected to weak nodes. A state-of-the-art Modular Static Synchronous Series Compensators (M-SSSC) application is studied in detail. The analysis is supported with a set of simulations in DIgSILENT PowerFactory®, comparing HVDC-LCC link performance with and without M-SSSC.

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.

Real-Time Operation and Congestion Management Validation of Modular Power Flow Controller on a 150 kV Transmission System

Real-Time Operation and Congestion Management Validation of Modular Power Flow Controller on a 150 kV Transmission System

IPTO, the Greek Transmission System Operator, describes their experience installing and testing modular power flow control technology. A post-contingency overload was identified and without any action would result in uneconomic dispatch of generation. Since this need was short-term, a mobile unit of modular power flow control was installed to resolve this constraint. Two representative use cases are presented – manual operation and automatic operation under an N-1 contingency condition. Results validate the device’s ability to redirect power flows to adjacent lines and effectively mitigate congestion.

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.

Advantages of M-SSSC Devices over Traditional Series Compensation

Advantages of M-SSSC Devices over Traditional Series Compensation

Hunt Energy Solutions collaborated with Smart Wires to undertake a technical analysis of modular SSSC compared with traditional series compensation. PSCAD simulations run on the IEEE Second Benchmark Model demonstrated that modular SSSC solutions do not resonate at any frequency. Additional advantages of modular SSSC explored include: increased control capabilities, minimal impact on protection system, higher resiliency, reduced substation footprint, quicker deployment time, greater flexibility in deployment siting and optionality in future scalability and redeployability.

Using advanced modular FACTS to increase flexibility of distribution networks and enable the connection of more distributed energy resources

Using advanced modular FACTS to increase flexibility of distribution networks and enable the connection of more distributed energy resources

UK Power Networks undertook the “Loadshare” project – an implementation of modular FACTS on the UK distribution network. This installation utilizes novel technology and a load-balancing algorithm to optimize loading on three parallel circuits and maximize network transfer capacity in real-time. It resolves network constraints, allows new DERs to connect and maximizes use of existing network without the need to pursue costly, time-intensive and disruptive system reinforcements.
