Embodiment Construction
[0053] The post-failure power shortage optimization and allocation method of multi-DC sending-end power grids provided by the present invention includes: reading relevant data of power grids and analyzing and processing the data; Judgment and positioning; calculate the actual power deficit of the whole network after various control measures work; calculate the power deficit apportionment of each provincial control area and carry out safe return to school: if the safety constraints are violated, calculate the power of each provincial level through the regional equivalent power generation sensitivity The correction amount of the shortfall power allocation in the control area; the power shortfall allocation amount is sent to each provincial control area by means of forwarding and remote adjustment, and returns to zero. By considering the actions of multi-level scheduling and multi-type control measures after the failure of the multi-DC sending-end power grid, the method realizes t...
