Control of energy transfer between a storage battery and the electricity grid

Abstract

This paper studies the transfer of energy between the low-voltage grid and a battery through an inverter. The inverter is used to control the transfer of energy from the battery to the grid. The concept of multilevel voltage source inverter is described. A Takagi Sugeno fuzzy controller is employed to control the voltage inverter to ensure a constant DC link voltage. The gains of the controller are calculated using linear matrix inequalities (LMI). The stability analysis of the system is performed using the Lyapunov and H-infinity theorem performance. The results of the simulation are made using MATLAB / SIMULINK to test the effectiveness of the proposed control algorithm.The validity of the model and its control strategies are greatly confirmed by the extensive simulation results.
