Operation and Maintenance Costs Allocation Model of Grid Project Based on Performance Value

Under the new round of power market reform policy, strengthening the life cycle economic evaluation of power grid projects is the key to speeding up the transformation and upgrading of power grids and improving investment efficiency. Considering that the operation and maintenance costs of power grid is unified accounting, how to calculate the operation costs of single grid project scientifically and rationally is the key to conduct economic evaluation. Firstly, the multi-factor relationship between grid operation costs and the substation capacity, line length, transmission and distribution volume and fixed asset value is analyzed to determine the key factors. Then, the operation and maintenance costs allocation model of grid project based on Performance Value is constructed in this paper. Finally, the operation data of a provincial power grid company is selected as a sample to calculate the operation and maintenance costs of different power grid projects, which verifies the effectiveness of the model.
