The invention relates to the technical field of power grid load control, in particular to a power grid load dynamic balancing method and system, and the method comprises the steps: obtaining all electric vehicles which are accessed to a smart power grid at all adjustment moments, and the predicted residual charging duration and charging power of each electric vehicle, acquiring power load data of each power grid node at each adjustment moment; determining a first electric energy influence coefficient, a second electric energy influence coefficient and a comprehensive electric energy influence coefficient of each power grid node at each adjustment moment; acquiring a model for simulating the change of the power grid quality of the line where each power grid node is located along with the load; and based on the model and a preset target, determining a target function in a particle swarm optimization algorithm, and based on an optimal solution of the target function, dynamically balancing the charging load of the smart power grid. The invention aims to improve the stability and reliability of the optimized smart power grid in each region, so as to better realize the dynamic balance control of the power grid load.
