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
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.

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
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
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
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.

Evaluating Modular Voltage Source Converter Based Technology in the GB Transmission System with EMT Studies
National Grid collaborated with Smart Wires to evaluate the feasibility of Voltage Source Converter power flow control on the UK transmission system. System performance under various scenarios was examined using EMT simulation software. Dynamic performance studies and protection studies were completed. No adverse impacts were observed from pre-and-post-fault transient perspective. There was also no adverse interaction with other nearby active network components.

Planning of anefficient power system with the use of modular staticsynchronous series compensation to enable flexible operational services
This paper outlines the increasingly changing network issues that arise in a distribution network and the ability of MSSSC’s to mitigate these issues. The paper will show how a deployment of MSSSC’s can enable the efficient use of providers of flexibility services like storage or electric vehicles. The paper will also show how MSSSC’s can be repurposed from ampacity issues, to voltage and transient stability issues through to harmonic, phase balancing and temporary overvoltage issues in support of delivering these flexibility services. Supporting cost benefit analysis in the paper will evaluate the cost effectiveness of this modular power flow deployment approach and the value fromthe resulting flexibility services.
