Mechanism and data-based modelling method of photovoltaic energy storage and transmission system

The power system model with power electronic equipment is usually a mechanism model, which needs to solve largescale nonlinear differential algebraic equations. The solution process requires a large number of iterations, with a large amount of calculation. To address these issues in the mechanism model, a mechanism and data based modelling method based on artificial intelligence algorithms is proposed. This method replaces some complex mechanism models with data models, which can reduce the problem of requiring a large number of iterations for power electronic devices in the mechanism model. By controlling the sampling time, the accuracy control of the mechanism and data based model is achieved, finally, the mechanism and data based model of photovoltaic energy storage and transmission system is completed, improving the running speed.
