Power Quality Improvement in Grid Connected Hybrid Distributed Energy Resources

Renewable energy (RE) sources solar as well as wind are the two essential energy sources found free of cost in nature. It has been used from past few decades to generate electricity and minimized the use of conventional sources of energy to save the environment. Analyzing the environmental conditions suppose there are conditions like power cut, no sun, no wind to generate electricity from hybrid, then there can be a substitute as fuel cell. Therefore, the contemporary methodology involves the control operation to fulfill the initial requirements of hybrid system maximum power tracing, input DC voltage & exchange amongst the RE sources transported to interlink. Proposed system is a fusion of three sources of energy i.e., photo-voltaic (PV), wind (WECS) and fuel cell (FC) hybrid system which gives efficient power compared with PV/wind hybrid. The power oscillations for an interlink could be condensed by Adaptive Neuro Fuzzy Interference method (ANFIS) based maximum power point tracking (MPPT) system. In this paper the hybrid system is compared with Incremental Conductance method (ICM) with Hill climb search (HCS) principle linked to ANFIS controller and fuel cell (ICM-HCS ANFIS & FC), without MPPT controller and without ANFIS controller. The proposed system satisfies the objectives required using a software called MATLAB/Simulink. Simulation results substantiates the power generated in proposed system & gives efficient power with dwindled total harmonic distortion (THD).
