Optimal control of load frequency of multi-region interconnected power system based on mutual benefit of wind,solar,water,thermal and storage power
Aiming at the characteristics of interconnection and multi-source in modern power systems
a heuristic intelligent optimization algorithm is proposed to assist multi-area interconnected power systems with wind
solar
water
thermal storage to optimize load frequency control. This method takes the area control error of each region as the objective function
and uses the advantages of whale intelligent optimization algorithm
such as strong robustness
high solution accuracy and fast convergence speed to jointly optimize the parameters of the PID load frequency controller in each region
so that the system can maintain frequency stability and long-term safe operation under various random disturbances. Finally
a three-area interconnected power system model with wind
solar
water and thermal storage is established to compare the frequency and tie line power deviation of the interconnected power system in different optimization tuning methods
and test the stability of the system in different regions under different disturbances and the effectiveness of the proposed method. The experimental results show that the coordinated optimization tuning method of the multi-area interconnected load frequency controller adopted in this paper effectively improves the stability of the system
