Design and control of grid-connected solar-wind integrated conversion system with DFIG supplying three-phase four-wire loads

<p>This paper describes the architecture and control of an autonomous hybrid solar-wind system (AHSWS) powered distributed generation supplying to a 3ϕ-4 wire system. It includes nonlinear controlling technique for maximum power point tracking (MPPT) used in doubly fed induction generator dependent wind energy translation scheme solar photovoltaic (SPVS). In model, DC/DC converter output from PV is explicitly coupled with DC-link DFIG's back-to-back converter. An arithmetical model device developed, derived using suitable d-q reference frame. The grid-voltage-oriented vector regulation required manage GSC keep steady-state voltage DC bus adjust reactive on grid side. Also, stator-voltageoriented offers stable function DFIG regulate RSC stator edge active management this approach. being maintain SPVS. A Perturb & Observe method tracing simulation designs 4.0kW 4.5kW array simulator are built-in SIMPOWER software kit MATLAB, it shown achieve optimum efficiency under various mechanical electrical circumstances. can produce rated frequency both scenarios.</p>
