Converter Control During Low Voltage Ride Through Operation for Grid-Interfaced Solar PV Battery Assisted System

Also Available Domains DC - AC Converters

Project Code :TEPGPS775

Objective

Objective: The objective of this project is to develop an efficient control technique for grid-interfaced solar PV-based distributed generation systems, allowing the DGS converter to remain connected to the grid during voltage sags and unbalanced power generation.

Abstract

Abstract: This paper presents the grid-interfaced solar PV battery assisted system for balanced as well as unbalanced power generation along with low voltage ride through (LVRT) functioning is presented. An efficient and simple control technique is developed for the system, such that the DGS converter stays connected to the grid under fault conditions till the LVRT required standards are fulfilled. The dc-link voltage variations and LVRT control are achieved by the battery energy storage bidirectional dc–dc converter. The positive sequence grid current components are considered to meet the LVRT standards. The controller ensures that the DGS converter currents are within the rated limits. The presented control strategy of DGS converter operation during voltage sags and unbalanced power generation is simulated and validated in MATLAB/Simulink.
