Virtual Power Plant Management Using PID Controller

Virtual Power Plant (VPP) is a reliable system for energy production and its attractiveness comes from the fact that VPP can control the energy production to fulfill the demand of consumers. However, the delay in communication and the varying output of the Distributed Energy Resources (DER) can cause instability in the system and the VPP will then operate in a suboptimal condition. Therefore, this project aims to design a VPP system that uses a PID controller to achieve a stable signal that can deliver power efficiently with minimal delay for a solar and wind farm with load. From observation, the tuning of the PID controller's proportional gain (Kp), integral gain (Ki), and derivative gain (Kd) result in a signal with reduced rise time and overshoot, eliminating steady-state error, improving transient response, and increasing the stability of the system. The simulation observes the performance of PID with a reference voltage of 25 and 30 V. The output voltage is constant throughout the simulation proving the stability of the circuit while eliminating errors.
