Day-ahead electric power spot market clearing safety checking method and device and storage medium

Abstract

The invention discloses a day-ahead electric power spot market clearing safety checking method. The method comprises the steps of constructing and solving a SCUC model and an SCED model of day-ahead electric power spot market clearing based on an initial water level cross section area value, and obtaining power generation plan parameters and water abandoning flow of a hydroelectric generating setwhich is pre-cleared in the day-ahead market in each time period; sending the power generation plan parameters and the water abandoning flow to a hydropower station allocation system, and calculatingan accurate water level value of the hydropower station in each time period; comparing the accurate water level value with a preset water level control constraint limit value; and if the comparison result meets the water level control requirement, outputting the control quantity of the hydropower station power generation plan based on the accurate water level value. According to the invention, reference data for feasibility judgment of the clearing result of the electric power spot market and selection of correction measures can be provided for a dispatching institution, so that the reliability of the clearing result of the electric power spot market and the timeliness of clearing calculation are ensured.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a safety checking method, device and storage medium for clearing the day-ahead power spot market. Background technique [0002] With the gradual advancement of the construction of my country's electric power spot market, the traditional power dispatching and power generation planning models are changing. It is necessary to comprehensively consider the constraints of power supply and demand balance, unit physical characteristics, and power grid security, so as to minimize the cost of power generation or maximize the benefits of the whole society. Turn it into a goal and complete the preparation of the unit's day-ahead and real-time power generation plan. Market-based transactions make the operation mode and power generation plan more diversified, and it is necessary to reasonably control the security check risk brought by the uncertainty of the power grid. Therefore, under t...
