Simulation of Large-Scale Smart Grid Voltage Fuzzy Control Model
In the process of fuzzy control for large-scale smart grid voltage,the fixed reactive voltage regulating boundary makes it impossible to reflect the influence of voltage on reactive power; consequently,on-load voltage regulating taps and parallel capacitor groups are frequently demanded for voltage regulation,leading to low regulation accuracy.Therefore,this paper puts forward a voltage fuzzy control algorithm for large smart grid based on TS-PID.The mathematical model for large smart grid voltage is analyzed; the objective function and constraint conditions in quadratic programming form for large smart grid voltage are defined ; the general form of the linear PID controller is analyzed;the open-loop transfer function and the closed-loop transfer function are defined for large smart grid generator active power channel.TS-PID controller combines the linear PID control with T-S model,and reduces the frequency of voltage regulation through local nonlinear control.The simulation results show that the proposed algorithm has high precision and effectiveness.
