Title:
STABLE CONTROL METHOD AND APPARATUS FOR AC-DC HYBRID POWER GRID AFTER DC BLOCKING
Document Type and Number:
WIPO Patent Application WO/2023/179044
Kind Code:
A1
Abstract:
A stable control method and apparatus for an AC-DC hybrid power grid after DC blocking. The method comprises the following steps: grading a power grid operation means; calculating the maximum control measure quantity of a power grid frequency constraint, the minimum control measure quantity of a power grid voltage constraint, and the minimum control measure quantity of a power grid power angle constraint under each grade; and according to the calculated maximum control measure quantity of the power grid frequency constraint, the minimum control measure quantity of the power grid voltage constraint, and the minimum control measure quantity of the power grid power angle constraint under each grade, selecting the optimal control measure quantity to perform stable control on the power grid after DC blocking. In the method, the control measure quantity can be selected according to actual conditions to perform stable control on the AC-DC hybrid power grid after DC blocking of the power grid, the principle of a stable control policy calculation method is clear, simple, and direct, and analysis and calculation time can be shortened.
