Load frequency modulation optimization scheduling method considering power distribution network constraint condition

The invention discloses a load frequency modulation optimization scheduling method considering a power distribution network constraint condition, which belongs to the technical field of load side frequency modulation. Power grid nodes participating in frequency modulation and the capacity of each node participating in frequency modulation are determined through a genetic tabu search algorithm; a genetic algorithm is firstly used to use the total capacity of temperature control loads provided by a scheduling center and participating in auxiliary frequency modulation and the number of power distribution network nodes participating in frequency modulation as basic data for calculation, and a local optimal solution based on the genetic algorithm is obtained; and the optimal solution is then used as an initial solution of a tabu search algorithm, and through calculation, the optimal solution of the genetic tabu algorithm based on the basic data is obtained. The optimal solution is the optimal solution of participa
