Abstract

The invention provides a frequency dynamic simulation method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring power load node frequency deviation simulation information; inputting the power load node frequency deviation simulation information into a target load simulation model to obtain power load node active power deviation information, wherein the target load simulation model is constructed according to a power load node frequency dynamic measurement curve and a power load node active power dynamic measurement curve after power disturbance of the power grid occurs. By constructing a target load simulation model, the input of the model is power load node frequency deviation simulation information, and the output of the model is power load node active power deviation information, the load simulation model suitable for dynamic frequency simulation can be accurately obtained, an important model basis is provided for dynamic analysis and operation control of the power grid frequency, therefore, reliable operation of the power grid is effectively ensured.

Description

technical field [0001] The invention relates to the field of power system analysis, in particular to a frequency dynamic simulation method, device, electronic equipment and storage medium. Background technique [0002] With the increasing proportion of new energy sources such as wind power and photovoltaics in the power system, the frequency security problem of the system is highlighted, and the frequency deviation under power disturbance becomes larger. Accurately simulating the frequency dynamic process of the system under power disturbance is of great significance to ensure the system frequency security. [0003] The load model has an important influence on the system frequency dynamic process. In frequency dynamic simulation, the main focus is on the change of load active power caused by frequency change. The traditional static load model considering the load frequency adjustment effect coefficient is too simple and does not take into account the load dynamics; while t...
