Problems solved by technology

[0007] The purpose of the present invention is: in order to solve the deficiency in the prior art that cannot fully reflect the system frequency security under large disturbances, to propose an optimization method for unit day-ahead power generation planning and spinning reserve configuration that takes into account frequency security constraints. Based on the day-ahead power generation plan and spinning reserve configuration method under some network security constraints, the frequency security of the system is introduced into the security constraints, and the reliability probability index of spinning reserve power is proposed

Abstract

The invention discloses an optimization and arrangement method for generation unit ahead generation scheduling and spinning reserve within frequency security constrains, and is applicable to configuration optimization of power generation system ahead generation scheduling and spinning reserve combining economy and reliability under large disturbance. According to the invention, the method herein, on the basis of current configuration optimization of power generation system ahead scheduling and spinning reserve, introduces frequency security to constraining conditions, so that the reliability of optimization is increased. The method also increases an evaluation index for spinning reserve which takes frequency security into consideration. Compared with prior art, according to the invention, the method can obtain a method for configuration optimization of the ahead generation scheduling and spinning reserve that combines economy and reliability.

Description

technical field [0001] The invention belongs to the field of power grid dispatching operation control, and in particular relates to a day-ahead power generation plan and rotating standby optimization arrangement method of a unit considering frequency safety constraints. Background technique [0002] In recent years, with the access of large-scale new energy and large-capacity AC and DC power sources and the participation of demand-side response, my country's energy structure has undergone tremendous changes. The safe and stable operation of the system has brought many problems. In order to maintain the reliable operation of the power system, the power system must be equipped with a certain capacity of spinning reserve to ensure the normal operation of primary frequency regulation and meet the rapid active power requirements of the system under various operation and accident situations. Therefore, in order to maintain the economic and stable operation of the whole network, co...
