The design of the PI controller with SmartCtrl for the Solid State Transformer in the solar farm application

Abstract

This paper presents design and control a suitable power electronics transformer (Solid State Transformer, SST) that is suitable for applying to be application in solar farm in Thailand by using Power Simulation Version 9.1 (PSIM 9.1). SmartCtrl is a toolbox of the PSIM 9.1 program that is used to design PI controllers and find the optimal gain automatically. The advantages of designing a controller with SmartCtrl are used to interface or work with other applications, simplified to use and not complicated, simulation results are easy to understand and analyze, and the controller from the design is stable. The PI controller from the design from the SmartCtrl to for using with Solid State Transformer in solar farm applications work satisfied and very well as confirmed by the simulation results.
