Fast Power Flow Calculation Of Complex Distribution Network

Under the background of grid connection of distributed new energy, the power flow of distribution network will also change dynamically due to the characteristics of distributed new energy. Therefore, multiple flexible resources are required to participate in the coordinated regulation strategy of distribution network, and the premise of which is to obtain the power flow information of relevant branches of distribution network within a short period of time. Therefore, based on the concept of equivalent topology in circuit theory, this paper conducts equivalent processing on the unrelated parts of complex distribution network and combines Newton method to quickly get the power flow information of main branches.
