Technique for Overall Dynamic Simulation of Electric Power Systems

摘要

The overall dynamic simulation of electric power systems (mnemonically called OVALDY) covers in one run the domain for which several different simulations are usually needed. The program accomplishing this simulation technique can replace those for dynamic, mid-term, and long-term simulation, of course with acceptable computational effort. The simulation technique OVALDY uses a single-step implicit integration method. The size of the integration step is automatically controlled by the required solution precision and the transient behaviour of the simulated system. At the beginning and immediately after a system change (caused by the simulation), the step is small; it increases while the transients die out (a ratio of 12467 was observed over a simulation time of 6 minutes).
