1996 Blackout – Case setup time
West Coast Heat Wave On July 17-24, 2006 – Case setup time
2009 – BPA Technology Innovation Study automation project – Fast & Reliable network model
2011 Arizona-Southern California black Next day study
Future hours study tool More complicated than next day study
Timing consuming to setup
Achieve convergence solution
Tools help meet NERC Reliability Standards: TOP-00-4
FAC-011-2,3
FAC-014-2
FUTURE HOUR STUDY BACKGROUND
At each forecasted t ime, the fol lowing needs adjustment: Load
Area
Zone
Individual Loads
Injection Groups
Generation
Zone
Injection group
Units
Stations
Interchange
Voltage schedule
Topology Changes
So many data points to be modified Time consuming
Error prone
Not repeatable
Solution may not converge
WHAT IS THE CURRENT PROBLEM?
Load
Interchange
Generation
Topology Changes
Voltage Schedule
WHY WE NEED A TOOL?
Repeatability
Fast
Accurate
PROCESS OVERVIEW
State Estimator /
Seasonal Case &
Forecast Data
Base Cases
(Future Time)
Planned Outage Cases
Study Applications
Visualization & Reporting
WHAT THE FORECAST BASE CASE
CREATION TOOL DOES?
FUTURE HOUR STUDY AUTOMATION TOOL
Future hour base
cases
SE /WECC cases
Maxisys Future Study Apps
Planned outage
Forecast info.
Peak Daily reports or customized reports
PV, QV analysis SOL Path analysis
Contingency analysis Cascade Analysis
CASES GENERATED BY TSA TOOL
Peak - Heavy - Light load
15 min, 30 min, 45 min, 1 hour, 2 hour, 4 hour, 8 hour, 16 hour 24 hour
Next Hour Next Week
Outage
Next Month
Flexibility to generate different cases
HOW THIS TOOL CAN WORK WITH OTHER
TYPE OF DATA?
Peak format data
CSV file upload
Data entry screens
Maxisys can write custom interface to take the data and load to forecast tables.
Maxisys can customize the error checking based on the system.

Path SOL
TS
Cascading
Run on Multiple cases and generate summarize results
Can analyze multiple cases and summarize the
results
One does not have to run one base case at a time
Save time for study engineers
Easy to identify problems
Repeatable process
STUDY APPLICATIONS
REPORT
Generate report automatically
from
Base case
Forecasted case
Contingency analysis
Path SOL Results
Avoid manual entries
Saves time
Repeatable
REPORT
Most powerful platform for future hour studies compared to any tools available in the market
Easy to use, repeatable, fast and accurate
Uses proven Powerworld powerflow
Can take dif ferent types of forecast
Load – Area, zone, injection group and individual loads
Gen – units, substation, injection group
Outages – Switches or lines
Voltage schedule
Net interchange schedule
Automatically report can be generated
Can customize application, interface and report generation based on your system needs.
