Abstract
This paper deals with a multi objective control strategy to control the double boost sepic converter (DBSEPIC) based grid interconnected inverter using synchronous reference frame (SRF) control. In the process of renewable integration grid interactive inverter with suggested control can be economize as a 1) power allocation and control between the inverter and grid for load, 2) retrenchment of harmonics in source current, 3) reactive power compensation. In this proposed SRF control strategy there are two different types of controllers are used one is PI controller and another one fractional order sliding mode controller (FOSMC). The simplicity of PI controller and robustness of FOSMC utilised here. The performance of two controllers is compared in terms settling time, peak overshoot and THD through simulation results.
