Converter station and AC power grid optimal reactive power exchange capacity determination method

The invention discloses a method for determining the optimal reactive power exchange capacity of a converter station and an alternating-current power grid, and belongs to the technical field of power transmission optimization. The invention provides a method for calculating the load flow of an AC/DC interconnected power system based on an alternating solution method, and provides a method for calculating the load flow of the AC/DC interconnected power system based on the load flow calculation of the AC/DC interconnected power system. And analyzing and determining the optimal alternating current filter input group number of the converter station and the optimal reactive power exchange capacity of the alternating current and direct current system under different control targets. The calculation result provided by the invention can be used as a proper method for researching the redundancy of the converter station under the alternating current capacity of the minimum filter and the absolute minimum filter bank un
