Modeling and Real-Time Simulation of Photovoltaic Plant Using Typhoon HIL

Abstract

This paper presents the hardware in -the loop (HIL)-based test bed for development, testing, and verification of PV plant operation. Many advanced control strategies have been developed to achieve these goals. However, final development and validation of the controls can be difficult due to the need for large and costly hardware test beds. Real-time hardware in the loop (HIL) simulators can enable the emulation of test beds while developing the real-time control hardware to implement and verify theoretical optimal control strategies. The PV simulated test bed is tested for different engagement of load and charging/discharging of the battery. Perturb and observe technique is used here to trace the maximum power point in the PV plant. Typhoon HIL (version 402) software is handed down for carrying out the simulations.
