Electromechanical simulation modeling method, system and medium for converters in electrochemical energy storage power stations

Abstract

This invention discloses a method, system, and medium for electromechanical simulation modeling of converters in electrochemical energy storage power stations. The method includes establishing an electromechanical simulation model of the converter; determining the parameters to be optimized based on the model; using the overshoot, response time, and settling time of the model under different parameters as fitness functions; using the parameters to be optimized as particles in a particle swarm optimization (PSO) algorithm; performing iterative optimization using PSO; and outputting the particle with the lowest fitness as the optimal parameter. This invention targets modeling and analysis applications, focusing on the power response characteristics of energy storage power stations after grid connection. By extracting the overshoot, response time, and settling time of the power response as indicators to construct a fitness function, and combining field measurements with simulation comparisons of the converter electromechanical simulation model, a highly accurate electromechanical simulation of an energy storage power station can be conveniently and quickly established for computational analysis of energy storage grid integration.
