Improve Power Flow Control and Performance Analysis of MVDC Grid Connected PV System

In this study a control strategy of two-level Three-phase grid connected PV system by using SVPWM method is proposed for distribution and generation system. Traditional grid rectifier brings a lots of harmonics pollution, to decrease these harmonics, in this control system technique a double closed loop control based on. (ISMC). Integral. Sliding. Mode. Control. internal current loop and voltage control external loop is presented. The main objective of this controller is, low error (SS) steady state, enhanced voltage regulation, unity power factor, little (THD) total harmonic pollution distortion and small disturbance taken into consideration. By using Matlab/Simulink software simulation results shows the proposed control system is effective, good dynamics and fast response which open new insights in distribution systems
