first v0.4.0 prototype
This is the first release in preparation for v0.4 of Vatic.
Changes from v0.3.0-a1 so far include:
- adding ability to specify initial on/off states for thermal generators, overriding the often unrealistic default initial conditions included in the grid datasets
- using ERCOT load forecasts instead of NREL load forecasts for the Texas-7k grid (ERCOT has less error and produces more reasonable results)
- setting all Texas-7k renewables to be fully dispatchable (Pmin=0) to match behaviour in the latest Texas-7k release
- fixing issues with missing line capacities for A1-A6 in Texas-7k
