Introduction Peak Hosted Advanced Applications

2 What is this project all about? Enhanced TOP situational awareness and ability to perform real-time assessments using Peak’s West-wide System Model (WSM) Provide tools to perform add-hoc studies using real-time state estimator solution as an input The full Peak RC operations, engineering, and IT teams supporting the tools Low cost, low maintenance for TOPs Project Intro

3 TOP system operators o Improved real-time situational awareness of existing pre- and post-contingency conditions o System operator ability to run studies using actual system conditions (state estimator snapshot) TOP Study or Planning Engineers o Engineer support operations with next-day or real-time studies using same model and data as Peak o Engineer can export model and studies for further analysis in PSLF, PSSE and PowerWorld Who Benefits

4 Peak RC o Additional eyes on the WSM as well as the Peak RC initiated model validation activities will result in significant improvements to the WSM and applications that use the WSM. o Data and application sharing will improve communications in real-time operations. Who Benefits (Con’t)

6 PHAAUG is a committee established by the signatories of the Peak Hosted Advanced Applications Agreement. Users Group meets monthly via webinar and twice a year face-to-face. Focused on supporting the development and delivery of training. PHAAUG (Peak Hosted Advanced Applications Users Group)

7 The primary objectives are to ensure members possess the tools necessary for adequate situational awareness (pre and post-contingency) and are able to meet compliance with pending NERC standards through the use of real-time contingency analysis software. In order to accomplish these objectives, PHAAUG shall: Develop training materials. Consolidate user feedback to provide to Peak’s PHAAUG representatives. Maintain a current list of members and their maintenance fee contributions. Evaluate performance of the HAA Agreement terms. Ensure dues are sufficient to cover costs and reserves. Prepare and submit an annual budget. PHAAUG Purpose/Responsibilities

8 Peakrc.org – Discussion Board The discussion Board is available for the HAA Customers to have an open forum for questions, comments, and the option to reply to one another.

9 The Enhancement log allows for the customer to request an enhancement on the functionality of the tools. The request will be reviewed by the User Group and Peak at the following monthly meeting. Peakrc.org – Enhancement Log

Next Steps

11 Peak Service o Year 1: $30k initiation, $75k service fee o Year 2 and 3: $75k each year Alstom License o Year 1: $80k - $120k, depending on size of system o Future years: 20% of year one license WISP WAN connection is additional cost (optional) Cost

12 Execute contract with Peak If interested in STNET, execute contract with Alstom Confirm your company has a Peakrc.org site Admin - this person will provide you access once contract has been executed by both parties. To Get Started

Tool Overview

15 Wide-area overviews Station onelines Why important? Primary input to State Estimator Five minute snapshots SCADA Situational Awareness

16 Calculates state of the system (voltage magnitude, angle, flows, injections) Identifies facility rating and bus voltage limit exceedances Five minute snapshots Real-time State Estimator Phase angle estimate with phase angle measurement (measurement in tan color).

17 Identifies the following unacceptable post- contingency system conditions: o Line/transformer facility rating exceedances o Bus voltage limit exceedances (high and low voltage) o Node-pair phase angle limit exceedances o Contingencies that result in an electrical island o Unsolved contingencies 8,000 + contingencies Five minute snapshots Real-time Contingency Analysis

18 Power Flow and Study Contingency Analysis (STNET) Used by operators for near real-time studies (what-if scenarios) Used by engineers for performing next- day studies, operations support studies Study Tools
