Technique to interconnect and control co‐simulation systems

Abstract

A Run Time Scheduler (RunTS) is presented, a minimalist Discrete Event Simulator able to sequence the operation of multiple simulators, coordinating a simulation of several elements so to form a whole system. Dynamic cause-effect chains may emerge. In operation the net simulation possesses a known steady-state other than when changed. RunTS controls the application of state-changes, passing these to specific simulators to determine new steady-states. Messages can pass between simulations concerning configuration data, commands and results. Simulators must meet connectability criteria. The method allows variable periods between simulation stages rather than a fixed tempo, and can undertake specific simulation sequences unique to each event, through use of a novel per-event state-machine. RunTS is part of INSim, a Smart Grid simulator working with a mix of components including Electric Vehicles, Smart Agents and OpenDSS, a power network analysis tool.
