Usually, the real-time digital simulation system of the primary power grid real-time simulation platform is selected as the primary real-time simulation system for the real-time simulation of the stability control system. A dynamically operating power grid model is constructed, the power output of the power source and the load size are adjusted as needed, faults are flexibly set, and the real-time waveforms of voltage and current under normal and faulty conditions of the power grid can be output in real time, which can reflect the dynamic characteristics of the power grid after the actions of automation devices such as protection, safety automatic devices, and excitation regulators in real time. The information provided by its simulation results is rich, and due to its real-time characteristics, it is very easy to realize for observing the fast transient process of high-voltage direct current transmission, and it is an excellent tool for constructing the laboratory simulation of the power grid security and stability control system.

[0003] However, the current hardware-in-the-loop experiment verification method has certain limitations. The main problem is that the constructed power grid model is based on a certain operation mode, and it is impossible to carry out multi-scenario verification on the stability control system. Especially considering that the new power system with a large amount of new energy has a large number of non-linear and strong uncertainties, it is necessary to further consider how to quickly adjust the power grid scenario and evaluate the adaptability of the power grid scenario; in addition, the current traditional stability control system experiment verification platform has poor accuracy of the primary power grid model and insufficient typicality of the power grid scenario, and cannot be directly used for the experimental verification of the adaptability of the stability control strategy of the new power system.
