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.

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.

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.
