Railbelt Inter-Area Oscillation Dampening Implementation and Validation Plan a. Siemens PTI provided their final report implementation and validation plan to improve inter-area oscillation damping among the interconnected ‘Alaska Railbelt’ electric utilities. This proposed plan is based on the recommended solutions outlined in Siemens PTI’s Final Report No. R067-20 ‘Analysis of Low Frequency Oscillations in the Alaska Railbelt System’ dated 5/13/20 (‘Siemens Final Report’). Where the Siemens Final Report specifies solutions to improve oscillatory mode response damping, the proposed implementation and validation plan focuses on how to achieve the damping objectives, what recommendations should be prioritized, and suggests methods to validate incremental improvements. 2. Implementation Schedule status a. Alaska Intertie SVC POD Tuning – Tuning and testing tentatively scheduled for June 7-11, 2021. i. AEA, working With Chugach and GVEA, has tasked GE to confirm settings and re- program Power Oscillation Damping (POD) parameters at Teeland, Healy and Goldhill SVC’s per Siemens PTI’s recommendations included in their final report. Project will require technical services support from Siemens PTI. b. Soldotna and Dave’s Creek SVC’s – Currently not on the Railbelt maintenance schedule. However, work is anticipated to take place summer 2021 i. Chugach, AEA, and HEA, working With the Bradley O&D have tasked ABB to confirm settings and re-program POD parameters at Soldotna and Dave’s Creek SVC’s per Siemens PTI’s recommendations included in their final report. Project will require technical services support from Siemens PTI. c. Bradley Lake – Currently not on the Railbelt maintenance schedule. However, work is anticipated to take place summer 2021. d. This work will be in conjunction with other HEA resources that were identified in the PTI Study as recommended solutions to improve inter-area oscillations. Specifically, Soldotna generator, Nikiski generator and their Tesla battery, currently anticipated to be fully commissioned by August 2021. i. HEA is currently developing an RFP that will include PSS and control system tuning and testing for all resources listed above. The tuning and testing requirements will also account for islanded operation. e. GVEA Battery – Currently not on the Railbelt Maintenance Schedule i. The PTI Study recommended the Power System Stabilizer (PSS) for the battery be disabled. 1. IOC to make an assignment to the Systems Study Subcommittee to develop a test plan to record and validate a controlled system event to measure system response with the PSS on, and then with the PSS disabled. Once the test plan has been determined, the SSS will provide the test plan to the IOC Chair who will then assign the Dispatch and Systems Operation Subcommittee to schedule the test. ii. Healy generators - Currently not on the Railbelt maintenance schedule. However, GVEA is working towards doing the work summer 2021. 1. GVEA has budgeted for the required work and has reached out to third party consultants for the purpose of confirming settings and perform the work to re-program the PSS for both units at Healy. iii. North Pole combined Cycle Plant - Currently not on the Railbelt maintenance schedule. However, GVEA is working towards doing the work in 2022 after evaluating the dampening results from the 2021 modifications at the other sites. iv. Chugach Beluga units 3 & 5 were recommended for tuning in the PTI study. However, those units do not run very often and therefore would not have a significant impact in mitigating inter-area oscillations. Intertie Management Committee Meeting Intertie Operating Committee Report March 26, 2021 1. Intertie Operating Committee (IOC) a. The IOC last met on March 12, 2021. b. Alaska Intertie Vegetation Management Policy i. IOC Maintenance Subcommittee is working on a joint program between MEA and GVEA. This program will merge best practices for GVEA and MEA to form a new policy. Development is anticipated to take two months to merge programs and develop a final product for IOC review. c. wildfire Presentation i. Dr. Jennifer Schmidt of UAA and Dr. Uma Bhatt of UAF gave a presentation on wildfire risk to the IOC on 3/12/21 ii. The presentation included information on daily, weekly, and seasonal fire and lightning predictions iii. They discussed vegetation and wildfire fuels data collection using LIDAR, drones, and satellite imagery 1. Historical data that provides changes to vegetation over time iv. They described an ongoing UAA research project to enhance Railbelt grid resilience against wildfires v. Their presentation was provided to all members and guests of the IOC that includes contact information. vi. Both Jennifer and Uma expressed interest in working with AEA and the utilities. d. Current studies i. Spin Study 1. SSS evaluated the four bids received during the RFP process. The committee performed an evaluation for each bid and selected the winner. MEA as the project Manager, sent out a notice of intent to the winning bidder on March 25, expect a response back soon. e. IOC assigned the SCADA and telecommunication Subcommittee with providing a scope of work and budget to improve communications from Teeland to Douglas and from Douglas to Healy. The SCADA committee will reach out to the Engineering and Relay Subcommittee to ensure the communication improves with include robust infrastructure that will provide a reliable path for communication assisted protection. Expecting draft scope and budget requirements next week. This project has been approved and will be funded by the $1.8M State appropriation. The project will be subject to the State procurement process.
