Design of an Effective Control Structure to Grid-Interfaced Solar Inverter with Fault Stability Performance

Abstract

Grid-interfaced solar power generation is intensifying its importance day to day due to the less cost and performance led to installation of MW solar power plants. With the increased system network, reliability and stability are most considerable factors. Under abnormal and faulted conditions, system has to connect to utility to improve stability of the system by supporting reactive power according to grid standards. In this research work, an advanced algorithm with efficient control structure has developed under different fault conditions (LLLG and LG faults). The research conclusions presented in this work will be helpful for the next-level smart grid control actions.
