Abstract

Abstract: To improve the operation and management efficiency of power grid enterprises, a provincially unified gateway-metering platform is established in Liaoning power grid, which can collect the gateway point data for management of electricity purchase and sale and analysis of line losses. A universal real-time line loss calculation method is proposed on the basis of existing research results and platform features and the impact and sensitivity of the model parameters is analyzed by means of the gradient and directional derivative. Moreover, a case study is used to prove the correctness and effectiveness of the method, and the results show that it is a useful reference for power grid planning and operation.

Key words: gateway-metering, line-loss calculation, gradient, sensitivity
