Research on Peak-to-Valley Load Balancing Method of Station Area Considering Source-Network-Load-Storage Interaction
Aiming at the problems of large power supply efficiency depletion and high peak-to-valley difference rate in the process of peak-to-valley load balancing control in low-voltage station areas,a peak-to-valley load balancing method of low-voltage station areas considering the depth of source-network-load-storage interaction is proposed.The source-network load depth interaction is analyzed and the corresponding influence model is constructed.The electrical parameters of peak-valley load balancing in low-voltage station area is selected and the theoretical control model of low-voltage station area is got.According to the multi-objective function solution method,the peak-to-valley load balance objective function and constraints are set.Utilize transformer to construct low-voltage station area source-network-load-storage balance adjustment hub to realize peak-to-valley load balance in low-voltage station area.The test results prove that the power supply efficiency loss is relatively low after the application of this method,and the peak-to-valley difference rate and load rate of the power supply unit are also reduced.The method has high application value,and can ensure the smooth operation of the power system.
