Abstract In order to make micro-grid modeling more accurate, an equivalent modeling method of micro-grid based on echo state network (ESN) is proposed. Under various operating conditions of the micro-grid, the micro-grid equivalent model based on the echo status network is constructed with the current and power data of the access terminal, which are taken as the input and output of the network respectively. Since the initialization parameter of echo state network no longer changes, and lacking adaptability, it lead to the inability to achieve optimal approximation. Fireworks algorithm has the advantages of explosiveness, instantaneousity, parallelism and scalability. In order to improve the accuracy of the modeling, the fireworks algorithm is used to optimize the parameters of the echo state network, a mathematical model by simulating the explosion of fireworks is established, and selects the best individual by calculating individual fitness values. By comparing with the measured simulation data of the micro-grid connected the grid, the rationality and accuracy of the modeling method are verified, which shows that the model has a good practical value.

Key words： metrology micro-grid echo state network equivalent modeling grid-connected fireworks algorithm parameter optimization
