Shore power system distribution network load flow calculation method based on forward-backward sweep method

The invention discloses a shore power system distribution network load flow calculation method based on a forward-backward sweep method, and belongs to the field of power distribution. The method comprises the steps: firstly performing data acquisition on a power distribution network containing a shore power system; building a power distribution system model on an MATLAB platform; carrying out load flow calculation by adopting a forward-backward sweep method; and finally, obtaining a power distribution network load flow calculation result of the shore power system through simulation. Aiming ata power distribution system with a radiation network structure, the method is irrelevant to node numbers in the forward and backward substitution process, and does not need a special number rule; thenumber of root nodes is set to be 0, and other nodes are numbered gradually according to any sequence, so that the calculation is simple, effective and feasible. The method can be widely applied to the field of shore power su
