Year: 2024

Type: article

Abstract: To improve power quality and power system stability, load frequency control (LFC) is introduced. The object of load frequency control has been transformed into a new power system with the participation of renewable energy sources with characteristics such as randomness, intermittentness, and volatility. In the interconnected power system, the control of load frequency plays an important role in the control of actual power, frequency, and link power. This paper mainly constructs a three-region interconnected power system model of wind, solar, thermal, and storage, combines fuzzy control and Proportional-Integral-Derivative (PID) control to build a fuzzy PID controller, uses the performance index time absolute error integral (ITAE) as the objective function, and an improved Sparrow search algorithm is used to optimize the proportional parameters of the fuzzy controller and the initial values of the PID controller, and the frequency deviation and the contact line deviation of the system are controlled in a smaller range.
