Problems solved by technology

[0003] However, during the implementation process, the inventors found at least the following problems in the traditional technology: most of the current power system dispatching methods only consider a single type of uncertainty when determining uncertain factors such as intermittent renewable energy output and load fluctuations In the event of credible and predictable accidents, the scheduling flexibility is poor

Abstract

The invention relates to a power system optimization dispatching method and device, a computer device, and a storage medium. According to the power system optimization dispatching method, an objectivefunction and basic constraints are acquired by processing coal-fired unit data and renewable energy unit data; based on a power transmission distribution factor, historical coal power output data, historical output data of renewable energy, and the load rate of each line, safety constraints are established; the safety constraints and basic constraints are used to solve the objective function to acquire the dispatching result; the impact of source and load uncertainty fluctuations on the operation of a power system is determined; when a credible and anticipated accident occurs, the power system can optimize the dispatching based on the dispatching result to improve the dispatching flexibility; the power system can adjust a dispatching strategy based on the dispatching result to meet the load requirements of the system; and the safety and economics of the operation of the power system are taken into account.

Description

technical field [0001] The present application relates to the technical field of electric power system dispatching, in particular to a power system optimal dispatching method, device, computer equipment and storage medium. Background technique [0002] With the expansion of power consumption scale and the continuous increase of electric load, the probability that the power system is in the limit operation state is greatly increased. In order to ensure the safe and stable operation of the power system, it is necessary for the power system to be able to adaptively and flexibly control its Operation mode, so that the power system can still respond appropriately in the event of credible and foreseeable accidents, that is, it is necessary to realize a resilient power system (Resilient Power System). [0003] However, during the implementation process, the inventors found at least the following problems in the traditional technology: most of the current power system dispatching me...
