Extenuation of Voltage Variations and Load Leveling in wind-DG Microgrid with Back Propagation Based Fuzzy Logic Controller

Authors(2) :-Y. Sunil Kumar Reddy, K. Raju

This paper proposes a hybrid design of the wind-DG (Diesel Generator) and the microgrid. The microgrid effectively uses the voltage source converter (VSC) as a voltage and frequency controller (VFC). The wind control is actively done by the permanent magnet brushless DC generator (PMBLDCG), and maximum power is potentially obtained by the algorithm of maximum power point tracking (MPPT) which effectively uses a boost converter combined with an incremental conductance (INC) advance. Some of the obtained power is supplied to the consumer loads and the surfeit amount of power is stored in the battery system (BS). BS is included at the end DC connection of VSC which gives load leveling during less or no wind conditions. At the time, when wind generation is unable to meet the load demand and with the combination of these energy resources, a reduced rating diesel engine driven squirrel cage induction generator (SCIG) feeds the loads and VSC at the point of common coupling (PCC). Back propagation feed forward (BPFF) control algorithm is utilized for VF control of VSC. This controller gives harmonic elimination, load leveling and reactive power compensation and furthermore regulates the voltage at PCC. This microgrid is modeled in MATLAB Sim power tools and simulation results are obtained to verify the appropriate working of both the converters and the overall system. A prototype of the microgrid is also developed to validate the design and model through test results. A comparative study of simulated and experimental work is given in detail.
