PROJECT TITLE :

Back Propagation Algorithm Based Controller for Autonomous Wind-DG Microgrid - 2016

ABSTRACT:

This paper takes under consideration wind-DG hybrid configuration with a voltage supply converter (VSC) as a voltage and frequency controller (VFC). Wind AC power generated by permanent magnet brushless DC generator (PMBLDC) is rectified into DC power, and most power is captured using maximum power purpose technique (MPPT) using a boost converter with incremental conductance (INC) approach. This power is stored into battery system (BS) and surplus is provided to the buyer masses. BS is hooked up at DC link of VSC which provides load leveling during less or no wind conditions. Diesel engine driven squirrel cage induction generator (SCIG) is feeding loads and VSC at point of common coupling (PCC) to support the system when wind generation is unable to fulfill out load demand. Back propagation feed forward (BPFF) management theme is used for VF management of VSC. This controller provides harmonics elimination, load leveling and reactive power compensation and also regulates the voltage at PCC. Microgrid is modeled with MATLAB Sim power tools and simulation results are made to verify the acceptable operating of each the converters and the system.
