In this paper an efficient design along with modeling and simulation of a transformer-less small-scale centralized AC?bus Connected Hybrid (Wind?PV) power system for supplying electric power to a single phase load. The main components of the hybrid system are: a PV generator (PVG); and an array of horizontal-axis, fixed pitch, small-size, variable-speed wind turbines (WTs) with direct-driven permanent magnet synchronous generator (PMSG) having an embedded uncontrolled bridge rectifier. An overview of the basic theory of such systems along with their modeling and simulation via Simulink/MATLAB software package are presented. An intelligent control method is applied to the proposed configuration to simultaneously achieve three desired goals: to extract maximum power from each hybrid power system component (PVG and WTs); to guarantee DC voltage regulation/stabilization at the input of the inverter; to transfer the total produced electric power to the electric load.
