AN EFFICIENT ASYMMETRICAL 15-LEVEL SMART INVERTER TOPOLOGIES FOR MICRO-GRID SYSTEM USING PSO-PID TUNING ALGORITHM

A unique fruitful problem solving platform in a global optimizing area has been implemented via particle swarm optimization. So far, most of the algorithms operate by ultimate usage of effective learning pattern, which process all the swarms used in a sufficient strategy. The grid connected AC module plays a perfect stand-by solution to co-power generation scheme. It combines both PV/FC as a single arrangement for proposed power conditioning topologies via effective control objective. This single module produces the constant output voltage as 100v to 400v from 10v to 40v input source by highly recognized boost converter and interfacing to gird system by proposed asymmetrical 15-level inverter topologies. The PSO-PID controller predicts the optimal modulation index & perfect switching angles for regulating the sudden variations from grid, eradicate the harmonics, improved voltage profile, better THD resolution. In this evaluation, proposed schemes support a pure sinusoidal current which is in-phase with grid outcome voltage. The proposed inverter topologies are validated with PSO-PID controller by advanced multi-carrier modulation schemes are evaluated by Matlab/Simulink platform, pertaining results are conferred.
