Embodiment Construction
[0047] The present invention will be further described below in conjunction with the accompanying drawings.
[0048] Step 1: Simplify the power distribution network and perform particle swarm coding. The specific method is as follows:
[0049] S1-1: Coding does not consider branches that are not on the loop;
[0050] S1-2: Branches with the same ring-breaking effect are merged into a branch group, which is called a generalized branch;
[0051] S1-3: Use a particle dimension to represent a generalized branch in the network, and the size of the particle represents the branch number in the original network corresponding to this generalized branch.
[0052] Step 2: Particle swarm decoding, and the fitness function fitness corresponding to each particle is obtained through distribution network power flow calculation;
[0053]Step 3: Set the parameters of the improved particle swarm optimization algorithm, including particle swarm size M, learning factor c 1 and c 2 , the maximu...
