In view of the problem that the power load fluctuates greatly at peak time and has lower node power factor,and it is difficult to coordinate the differentiated demand,the self-adaptive response method of differentiated demand of the active distri-bution network considering the coordination of source-grid-load-storage is studied.The objective function is to fully meet the differentiated needs of end-users of the active distribution network based on the voltage stability standard,the frequency-type power supply rate standard and the time-type voltage deviation standard,combine with constraints,to build an active distribu-tion network source-grid-load-storage coordination optimization model.On the basis of meeting the constraints,this paper se-lects adaptive fireworks algorithm to solve the objective function of the optimization model,and obtain source-grid-load-storage coordination optimization results.The experimental results show that this method can quickly realize the good coordination of the source-grid-load-storage in the active distribution network.After coordination,the power factor of each load node of the ac-tive distribution network is 0.90,and the output voltage per unit of network is higher than 0.95 pu,which can guarantee the power supply quality of the distribution network.
