Abstract

The present application provides a day-ahead scheduling method and apparatus for a power system, an electronic device, and a storage medium, where the method includes: obtaining power system prediction parameters in a to-be-scheduled time period, where the power system prediction parameters include thermal power unit parameters, renewable energy station parameters, load parameters, energy storage station (ESS) parameters, node parameters, a transmission line parameter and other power gird parameters; constructing a day-ahead scheduling optimization model and generating multiple renewable energy power scenarios based on the power system prediction parameters; solving the day-ahead scheduling optimization model to obtain day-ahead scheduling results; verifying the day-ahead scheduling results based on the power system prediction parameters and the multiple renewable energy power scenarios; and in case that the verifying the day-ahead scheduling results successes, outputting the day-ahead scheduling results. In the method, the impact of the renewable energy station grid-connected proportion instructions on the renewable energy power scenarios is characterized by generating multiple renewable energy power scenarios, the voltage security for nodes in the power system is ensured by constructing the day-ahead scheduling optimization model, the feasibility of intraday power grid operation is ensured by verifying the day-ahead scheduling result, and the power system is safely and economically scheduled under the condition of voltage security.
