Three-phase LCL-Filter for Grid-Connected Inverter Using Cooperative Bacteria Foraging Optimization
Author:
Abstract: This paper establishes an LCL-filters design and control for three-phase grid inverter. The crucial object is to conquer optimum damping with a required system control bandwidth for the LCL-filter. This control technique is achieved by using Bacteria Foraging Optimization. Mathematical analysis has been introduced to investigate the steady-state and dynamic performances of the overall system. The proposed control method is using one set of current sensors for feedback control only. The proposed system is simulated and results are demonstrated that bacterial foraging optimization is a skilful clarification for implementing the best parameters of LCL-filters and PI current controller. Results support the proposed technique and highlight its practicability.
