Modified Direct Power Control of PV Sourced Inverter
P. Suganya and P. Sivakumar

Abstract: In this era of uneconomical energy resources there is growing concern about renewable energy. Out of this various method of harnessing renewable energy, solar energy is growing at a great pace. This study deals with the control of solar power supplied to the grid using Extends Direct Power Control method (EDPC) which is a generic approach of Direct Power Control (DPC). Current power availability of PV system is calculated using irradiance meter denoted by Ppv. This Ppv is compared with the required power of the grid and the error is calculated. The dc output of the photovoltaic (PV) system, in fed to the inverter. The controller consists of a Maximum Power Point Tracking (MPPT) block and a DPC block. MPPT generates reference voltage levels using which the error signals are generated. This error signal along with the feedback from the output of the inverter when fed to the multilevel DPC block generates the required control signals to the inverter. The power output requirements of the standalone grid are matched using the direct power control.
