doi:10.11985/2020.01.013

Abstract

Abstract:

As an important technical indicator in power supply enterprises, negative line loss management affects the economic benefits and lean management level of power supply enterprises. A method of loss allocation based on the absolute value of line loss sensitivity is proposed. Combined with the quoted power level of grid connected nodes, the network loss of transmission lines is corrected. The electricity market bidding is used to correct the network loss, and can also promote the power supply department to properly settle the network loss cost for each power generation individual, and help reasonable avoidance of network loss by all parties, avoid the loss of negative line loss settlement by the power supply department as well. At last, taking IEEE 2 machine 14-node system as an example, the feasibility of solving the problem of negative value of network loss is verified by the calculation, analysis and comparison of the example system.

Key words: Negative line loss, quotation correction, sensitivity analysis, power system
