A Linear-Implicit Quantized Devs Nethod For Very Stiff Electrical Networks Using A Latency Insertion Method

A Linear-Implicit Quantized State System (LIQSS) method is combined with a Latency Insertion Method (LIM) to create a practical and efficient approach for simulating the dynamics of very stiff electrical systems. The LIQSS method is used to asynchronously update each state in the system, where the LIM modeling method is used to decouple the electrical system model at the individual node level making the asynchronous solution possible. The DEVS specification for the QDL method is presented along with the detailed simulation procedure. The combined method is validated by simulating a 40-state network model with a stiffness ratio of 109.
