Computer modeling and simulation of MPC control for grid connected renewable power sources

Abstract

Renewable energy test site installed at NazarbayevUniversity in Kazakhstan is considered as a controlled plant for modeling, design and simulation of proposed model predictive control (MPC) technique for the power system with nominal power up to 10 kW. The mathematical and simulation model of the control plant assumes that disturbance from consumer grid side is generated by pseudorandom numbers. The control strategy relies on switching between several controllers LCL-filter and is shortly discussed. The MISO control system is designed using the switching between two MPC controllers. The results of simulation show significant reduction of THD value which proves the effectiveness of the designed control.Keywordscomputer modeling and simulation, renewable energy, model predictive control, LCL-filter.I.
