The balance of PV energy and user demands in grids by using a new configuration of a three level NPC Inverter.

D. Nitish Yadav, A.Pradeep Kumar Yadav


              In this paper a grid-connected solar PV system integrated with battery storage using a new configuration of three level NPC inverter has been designed using MATLAB/SIMULINK. Three-level space vector modulation technique is proposed efficiently that can generate controlled ac voltage under unbalanced dc voltage conditions. The proposed system having the capability of MPPT and ac side current control and also ability of controlling battery charging and discharging this will result better efficiency and balanced power flow control. The results of simulation are given to investigated the effectiveness of proposed methodology at several scenarios, including battery charging and discharging with different levels of the solar irradiation.
