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.

Integration of Series FACTS into Interconnect-scale Production Cost and Long-term Planning Tools

Integration of Series FACTS into Interconnect-scale Production Cost and Long-term Planning Tools

A power system simulation and planning platform called PLEXOS® was augmented to simulate five types of series FACTS devices. NYISO, ISO New England and PJM footprints – 14,000 buses and 2,500 generators – were evaluated for deployment locations. Results indicate that series FACTS devices can be optimally planned across an interconnect-scale system and the operation of the series FACTS devices can be simulated for an interconnect-scale system.

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.

FACTS and D-FACTS: The Operational Flexibility Demanded by the Transmission Expansion Planning Task with Increasing RES

FACTS and D-FACTS: The Operational Flexibility Demanded by the Transmission Expansion Planning Task with Increasing RES

This paper analyzes the effects of changing dispatch scenarios to transmission expansion planning and operation, and the associated financial impact. Case studies based on the Brazilian system are utilized to compare the ability of available technologies to realize the transmission expansion planning objectives. The expansion plans are compared based on operational performance and total investments.
