An Efficient Algorithm for Dispatch of Modular FACTS devices in Transmission Planning

An Efficient Algorithm for Dispatch of Modular FACTS devices in Transmission Planning               

This paper develops an efficient method to optimally dispatch multiple variable-impedance power flow control deployments to resolve post-contingency overloads from a planning perspective. The dispatch method is based on a PTDF DC power flow formulation and illustrated on the IEEE 39-bus test system solving with full AC power flow assumptions.

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.

Strategic Transmission Investment using Modular Static Synchronous Series Compensators

Strategic Transmission Investment using Modular Static Synchronous Series Compensators

Duke Energy, a major US utility, describes the application of modular SSSCs to enable strategic transmission investment. Modular SSSCs mitigate risk by alleviating overloads that could occur due to deferred projects. Duke evaluates the use of modular SSSCs to defer a reconductor for several years and finds this solution is lower cost, smaller footprint and greater flexibility than alternate forms of power flow control.

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.

Advancements in Distributed Power Flow Control

Advancements in Distributed Power Flow Control                                       

Many considerations for implementing advanced power flow control in real grids have been neglected in the past. This paper breaks down these neglected considerations. It proposes an agent-based power flow control system, including necessary hardware components, control algorithm, monitoring underlying distribution grids, communication technology and protocols, and the interface with the grid operator’s control center.

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.

Trends in Transmission Planning Uncertainty and the Impacts and Value of Leveraging Flexible Investment Strategies and Technologies

Trends in Transmission Planning Uncertainty and the Impacts and Value of Leveraging Flexible Investment Strategies and Technologies

This paper proposes a scorecard that was developed via input and review from dozens of utilities across the globe. It contains monetized and non-monetized metrics that represent best practices from throughout the industry. This tool offers a way for utilities to compare flexible solutions against traditional options, evaluate transmission investment decisions and improve their decision making process.

Study Results of the Impact of a Modular SSSC to Transmission Line Protection Schemes

DNV-GL completed a study to understand the impact of modular SSSC technology on line protection. The modular power flow control technology based on SSSC combined with a unique method for rapid bypass during line faults was found to have minimal impact on line protection.
