Problems solved by technology

The large-scale access of distributed new energy introduces new randomness and uncertainty, and the traditional backup configuration method will be difficult to adapt; the penetration rate of variable load in the distribution network is gradually increasing, and the change of its load characteristics has a great impact on the power grid. The Reliability Impact Is Gradually Showing Up

Abstract

The invention discloses a power system operation double-side standby configuration method, system, equipment and medium, and the method comprises the steps: carrying out the optimal configuration of the standby capacity of a power generation side or a user side through an uncertainty double-side modeling method on the premise of guaranteeing the safety and reliability of the system and no influence on the user load (consumer); and determining standby optimal configuration on the two sides by using an isomerism curve, and ensuring that the standby configuration is realized while the power unbalance amount caused by each uncertain factor in the power system is balanced at any time.

Description

technical field [0001] The invention relates to the technical field of power grid backup configuration optimization, in particular to a backup configuration method, system, equipment and medium for both sides of power system operation. Background technique [0002] When the power system is running, a certain amount of reserve capacity will be reserved to deal with load fluctuations, load accident removal, unit accident shutdown, etc. From the perspective of system reliability and security, it is necessary to configure as much spare capacity as possible, but too much spare capacity will increase the burden on the economical operation of the system. Generally, the reserve capacity can be simply determined according to the fixed proportion of the load carried by the system or the maximum capacity of a single unit. However, the requirements of power users for system reliability and security are constantly increasing, and the importance of power grid economy and low-carbon opera...
