The invention provides a wind and
light storage modular modeling method and
system oriented to an electromechanical
transient state of a power
system, relates to the technical field of
power system simulation, and aims to solve the problems that in the prior art, the requirements of a user on modular recombination and customized
adaptation of a model cannot be met, the model
reuse rate is low, the flexibility is poor, and the modeling efficiency is high. And a unified modeling
standard system is not formed yet, so that the development requirement of a novel power
system is difficult to adapt. Comprising the following steps: based on energy form decoupling, carrying out
modular decomposition and reconstruction on a wind and
light storage dynamic model, decomposing the model into three links of energy conversion and control, energy buffering and energy output and control, and constructing a hierarchical integrated architecture; and based on the hierarchical integrated architecture, modular sub-models corresponding to the fan, the photovoltaic device and the
energy storage device are constructed respectively, and dynamic combination is carried out to obtain a modeling result. According to the method, the problems in the prior art are solved, the model
reuse rate and flexibility are improved, and the
model simulation precision and efficiency are improved.
