Embodiment Construction
[0028] The present invention will be further described below in conjunction with the accompanying drawings.
[0029] The present invention proposes a safety and stability coordinated control method for power grids that takes into account the access of virtual synchronous generators. figure 1 , including the following steps:
[0030] S1 first conducts offline simulation for each fault in the expected fault set, and calculates the dispatch sensitivity of each virtual synchronous generator through simulation, thereby obtaining the dispatch sensitivity matrix. The obtained control sensitivity matrix has a one-to-one correspondence with the faults in the expected fault set. Faults correspond to different control sensitivity matrices, and the obtained control sensitivity matrices are pre-configured in the control sub-station of the new energy collection station;
[0031] The control sensitivity matrix corresponding to each fault in the expected fault set is an n-dimensional row vec...
