Design of Photovoltaic-Communication Co-simulation Module Based on TrueTime Toolbox

The existing power communication co-simulation methods commonly have such problems as time synchronization difficulty, complex data interaction interface, and insufficient dynamic simulation precision. In this context, for the sake of easy operation and accurate dynamic simulation of photovoltaic grid-connected system, a PV-communication co-simulation module is designed based on TrueTime toolbox. The designed co-simulation module can be implemented in the Matlab/Simulink simulation environment, and has salient merits of avoiding complicated time synchronization mechanism and data interaction interface design. In this regard, the proposed modular provides a simple analytical tool for researchers to simulate the impact of a planned communication network on the performance of a photovoltaic grid-connected system. Finally, the effect of the proposed co-simulation method based on the module is verified through typical test systems.
