Operation Expenditure Forecasting Model of Regional Power Grid Based on LS-SVM

The principle of “regulatory cost and reasonable returns” for transmission and distribution price has changed the profit model of the power grid enterprise, which puts forward a austere challenge on the operational management level and operation expenditure. The current operation expenditure management of power grid enterprise is relatively extensive. The operation expenditure is usually calculated by the asset scale and the empirically estimated proportional coefficient. This kind of management model has been unable to adapt to the new grid cost supervision environment. So, enhancing the forecasting accuracy of operation expenditure has become an urgent problem for power grid. Based on the analysis of the interaction of operation expenditure with multi-factors such as total electricity consumption, GDP, power consumption structure, effective asset value, variable capacity, and line length, operation expenditure forecasting model of regional power grid Based on LS-SVM algorithm is built in this paper. Finally, the operating data of a district power distribution company is selected as a sample to predict the operation expenditure in the future, which verifies the validity of the prediction model.
