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

Abstract

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

Design and implementation of optimal controller for DFIG-WT using autonomous groups particle swarm optimization

“…In (4) the actual parameters (tr, Mp, ts, and ess) are used to find the best solution for the objective function by ∑(𝑒𝑟𝑟𝑜𝑟𝑠) 2 of actual and desired parameters (trd, Mpd, tsd, and essd). In (5), The factor β is above 0.7 to minimize Mp and ess. meanwhile β is below 0.7 to minimize tr and ts [4].…”

“…Various control techniques, for example, Appling adaptive, and fuzzy logic. The famous proportional-integral (PI) controller ,which is widely used in WT due to it is simple [4] and other studies found in [5]- [7]. However, it is not easy to get the required performance if its parameters isn't tunned.…”

“…A power maximization algorithm is used to maximize the performance of the Solar PV array as integrated with DC-DC convertor to produce a required duty cycle [15], [16]. Several algorithms were proposed in the literature to track and extract the maximum power point (MPP) from PV array such as hill climbing algorithm and slide mode control [17].…”

Harnessing wind and solar PV system to build hybrid power system

“…Geology collected the most outrageous power using multi-input help converters for cream energy [25]. The plan and control of an autonomous hybrid solar-wind system (AHSWS) controlled scattered age framework giving to a 3ϕ-4 wire framework [26]. The diminishing of expertise effectuated by the unreplenishable energy determination in view of the plunge of oil subordinates has made a substitute necessity for maintainable force sources to expect an essential part in giving power at a greater extension.…”
