Active & Reactive power Control of Large scale Grid Connected PV system by Cascaded Modular Multi-Level Inverters withFuzzy Logic Control Approach

Abstract

Abstract-Due to its advantages like clean energy production and more abundance availability solar energy is the most concentrated topic from last 20 years. Grid connected PV system gaining its importance due to high demand of power across the globe. Now a days different topologies of Multilevel Inverters are developing. By using this multilevel inverters we can interface the PV systems with Grid easily and effectively. But PV system facing so many problems like power flow control and output voltage disturbances because PV systems produce irregular output voltages. This paper demonstrates the Cascade Multilevel inverter with Active and Reactive power control using Fuzzy logic control approach of for Grid Connected PV System. With the help of this model we can improve the performance of the total PV system. In this paper we proposed a 3-MW, 12-kV PV system with the Fuzzy Logic control strategy is modelled and simulated in MATLAB.
