Indirect Power Control Strategy for PV System connected to Grid

摘要

This paper proposed the indirect power control scheme using d-axis current control for grid connected PV system. This high generation of renewable energy increases the risk of grid instability using conventional current control scheme. In this paper variable reactive power and maximum active power is provided to the grid at different conditions using Id and Iq current control scheme to improve the grid stability as compared to conventional scheme. This reduces the reactive power stress on the grid and gives a smooth control of power. This scheme is simulated in MATLAB SIMULINK and results are discussed to validate the proposed control for grid connected PV system.
