Improved control systems simulation in the EMTP through compensation

The control systems, devices and phenomena modelled in TACS, and the electric network modeled in EMTP are solved separately with one-time-step error at the interface. This provides an efficient time-step solution, but there can be numerical stability and accuracy problems associated with the one-time-step error. This paper shows a technique which can eliminate the time delay, without having to use a simultaneous EMTP and TACS solution.<
