Latest enhancements

All of the enhancements since 2019 have been back-end or algorithmic related.  Major enhancements include:

• Moving solves to individual lambda micro-services.  This means each time period is solved on a separate machine and then the data recombined and published.  The impact is that solve times have been reduced by 3-4 minutes to only 20 seconds resulting in publication of data only 45 seconds after input data are published (and for HAEG 20 seconds after input data are published).
• Additional algorithms have been added to solve for QLD because a large number of constraints has been removed and a large number of new units has been added.  This means some of the solar farms are forecast in advance resulting in material errors for solar farm forecasts.  Thankfully there is no impact on other groups for nighttime and the impact on other group solutions is small during the day since the coefficients of the forecast solar farms are small relative to other terms.  The exception is CallideB which can have errors up to 70MW and SwanbankE which can be up to 50MW.  
• Improved monitoring.
• Improvements to database structure which reduces latency.  
• Improved redundancy which translates to better service level (currently 99.82% excluding AEMO issues publishing WAEG data).
