Abstract

The invention provides a method, device, electronic equipment and storage medium for power system backup reservation, wherein, the power system backup reservation method includes: acquiring the system load and new energy output data before the day; Output data, call the day-ahead reserve reservation model to calculate the day-ahead reserve reservation results; based on the day-ahead reserve reservation results, determine the combination result of thermal power units; obtain the system load and new energy output data in the current day; the combination of thermal power units based on the power system The result, the current intraday system load and the current intraday new energy output data, call the intraday reserve reservation model to calculate the intraday reserve reservation result. Through the optimization and coordination of multi-sequence backups between day and day, while ensuring the safety and reliability of system operation, the power prediction error is reduced, and the reserve reserve capacity is reduced, and finally the optimal scheduling effect is obtained with the balance between safety and economy.

Description

technical field [0001] The present invention relates to the field of power systems, in particular to a method, device, electronic device and storage medium for reserve reservation of a power system. Background technique [0002] In the daily power supply of the power system, in addition to meeting the expected load demand, it is also necessary to reserve active power reserves for the purpose of ensuring power quality and safe and stable operation of the system in emergency situations. This part of the reserved active power reserves is the spare capacity. With the development of wind power generation and photovoltaic power generation technology, the proportion of wind and solar energy in the power system continues to increase. For such new power systems with a high proportion of new energy, at present, the domestic new energy power prediction system has a prediction error of about 10%. %~25%, if the reserve is reserved according to the forecast error of new energy, a large a...
