Bug Fixes

  • Transient Stability: Version 20 includes a feature to specify the number of consecutive failed network solutions at which the simulation should abort. In Version 19 this is always hard-coded as 10. This was a good default when running Euler's integration method as there is only 1 algebraic network solution each time step, however in the second order there are 2 algebraic solution each time step. When using the second order method, Version 20 take the user specified value and multiplies by 2. Version 19 was not doing that. This patch changed it so that Version 19 now used a hard-coded value of 20 consecutive failed solutions to be considered as a reason to abort the simulation
