SAIDI & SAIFI Trends — 2015–2023 Reliability Improvement Track
⚠ SYNTHETIC DATA NOTICE: All grid frequency readings, voltage regulation data, reliability indices (SAIDI, SAIFI, CAIDI, ASAI), outage records, generation data, reserve margins, and bus measurements in this dashboard are entirely synthetic and randomly generated by AlphaStatLab for portfolio demonstration. No real utility, grid operator, or ISO/RTO data is represented. Real grid stability analytics solutions: alphastatlab.org
Methods: Frequency time-series generated with mean-reverting Ornstein-Uhlenbeck process around 60 Hz. Voltage deviations from normal distribution. SAIDI/SAIFI trends from linear improvement model + noise. Outage events synthetic log with realistic cause distribution. Chart.js v4.4.1. Font: Orbitron (Google Fonts).
