Accomplishments:
- Updated Multiperiod class to extract the SOC variable and related constraint dual variables during each iteration. I ran for 15 periods and battery SOC decreased linearly as expected until depletion.
- With latest battery model, SUGAR3 converges with a depleted battery SOC.
- Added previous solution initialization to the multiperiod class, which decreases solve times by 3X for each period after the initial one.
Progress Reflection:
- Multi-period is developing smoothly in cooperation with the Pileggi group battery model. I am happy with my progress, but I need to understand DDP better and how the algorithm converges across multiple epochs
Next Weeks Goals:
- Understand DDP, talk with Aayush
- Add renewable generation as negative PQ loads within the GLD file with a nominal power modified by a specific capacity factor each period.
- Validate single period solutions using a Grid-lab D testcase for 2bus network – talk with Elizabeth.
Convergence!
