Research on Grid Peaking Unit Load Optimization Allocation Method under New Energy Access
New energy access to the power grid will cause large fluctuations in the peaking unit load,resulting in a decrease in the security and stability of power grid operation.The grid peaking unit load optimization allocation method under new energy access is studied.The access problem of new energy in the power grid is analyzed and the relationship between new energy access and the depth of peaking unit peaking of the power grid is obtained.Based on the results of the correlation analysis,the objective function of grid peaking unit load optimization allocation is establised.Load rate,power balance,unit output,and output power are taken as constraints.The multi-objective particle swarm algorithm is used to solve the objective function of optimal allocation of grid peaking unit load and obtain the optimal solution of the objective function.According to the optimal solution,the optimal allocation of grid peaking unit load is realized.The experimental results show that after the application of this method,the amount of wind solar power generation blocked is low,the output of thermal power units and wind power farms is high,and the optimal allocation of grid peaking unit load is effective.The method can be widely used in the field of unit load optimization allocation to ensure the security and stability of grid operation.
