ANN and fuzzy logic controller design for hybrid wind/PV system connected to MV distribution grid

Abstract

PurposeThe purpose of this paper is to present a systematic design procedure along with modeling and simulation of a medium‐scale centralized dc‐bus grid connected hybrid (wind turbine (WT) and photovoltaic (PV)) power system (GCHWPPS) for supplying electric power to a three‐phase medium voltage distribution grid.Design/methodology/approachThe design, modeling, simulation and control of the GCHWPPS are achieved by using Simulink/MATLAB environment.FindingsThe case study shows that the proposed system configuration along with the suggested control schemes achieve rapidly, accurately, stably and simultaneously four objectives, i.e. maximum power point tracking of WT and photovoltaic generator, dc voltage regulation/stabilization at the input of the inverter, and high electric power quality injected into the grid from the inverter, fulfilling all necessary practical interconnection requirements while providing additional load power factor correction.Originality/valueAn effective intelligent dynamic control method is used to a proposed GCHWPPS configuration to simultaneously achieve the four mentioned practical objectives while meeting the grid requirements.
