Network loss allocation method based on power flow tracing method and electrical dissecting method

The invention discloses a network loss allocation method based on a power flow tracing method and an electrical dissecting method. The power flow tracing method and the electrical dissecting method are creatively utilized to reasonably and equally allocate the network loss in a power transmission network to generators and loads. The power flow tracing method is used for obtaining power and current contributions of each generator and each load to all power transmission lines. The electrical dissecting method is used for dissecting the power transmission network to obtain all sub-paths corresponding to each generator and each load according to the power and current contributions of each generator and each load to all power transmission lines; and the power loss sum of all sub-paths is the power loss which should be allocated to the corresponding generators and loads in an original power transmission network. According to the network loss allocation method, the allocated network loss values of each generator and each load can be accurately obtained; and the allocation process completely follows the circuit law, so that the network loss allocation method is equal and reasonable, simultaneously has the advantages of being simple to operate and convenient to use, and can be widely applied to power loss allocation of a large power network.
