“…Wind turbines, on the other hand, have a lot of inertia, which can be used to control system frequency [14]. The virtual inertia method is proposed to discharge the mechanical energy excess energy in the wind turbine to achieve variable speed operation.A variable speed generator is needed to match the wind frequency, which is where the doubly-fed generator appears throughout [15] [16].…”

The generate mechanical power or electricity is known as wind power or wind energy, Wind turbines convert the wind's kinetic energy into a mechanical energy-based combination of two or more energy sources that generate efficient energy power. In the existing method autonomous wind-solar hybrid energy system feeding 3-phase 4-wire loads, and it Contains some drawbacks output, not efficiency, high maintenance, Power quality is low, overcome the drawbacks wind system with AFPM feeding to improve power quality.Axial-Flux Permanent Magnet Generator for small wind turbine power generation systems with brushless motors synchronous machine. Because the generator's mechanical frequency changes, the rotor switching frequency must start changing to maintain the stator switching frequency constant. In a wind generator with variable speeds, low balanced dynamical stack, and varying wind accelerations, rotor excitation is permitted for a wind turbine's stator to supply a load or feed the grid. A boost converter is used to increase the DC voltage of the battery before it is given to the single-phase DC-DC Chopper, and the MPPT (Maximum Power Point Tracking) technique is used to maximize the energy output.When the switch is open, no current flows through it, converting the unregulated DC input to a controlled DC output with the desired voltage level, there is no voltage drop across the switch when it is closed in the DC-DC Chopper. The proposed system is simulated using MATLAB Simulink, the output result is improved and getting better efficiency when compared to the proposed method.

“…МПЖ може працювати в таких режимах: у режимі підключення до мережі [18][19][20][21], а також в автономному режимі [22][23][24][25][26][27][28][29]. У випадку використання СГЕ з підключенням до мережі основна увага в роботі та методах керування полягає в моделюванні МПЖ [30], регулюванні активної та реактивної потужностей [19,31,32], здатності витримувати провали в напрузі мережі [18,31] і компенсації несиметрії мережі [19,22,[31][32][33]…”

The variable speed power generation system based on a doubly-fed induction generator is the most popular in the wind industry. The stator is connected directly to the mains in such a generator, while the rotor is connected to the mains via a semiconductor converter. Low electric power quality increases energy and economic losses, leading to operational problems of production. Many publications discuss improving the electric power quality, particularly methods for eliminating harmonics for a power generation system based on a doubly-fed induction generator. Critical evaluation is needed to choose a method of eliminating harmonies for a particular case. The article presents an overview of different control methods for harmonic elimination in power generation systems based on a doubly-fed induction generator. Various strategies are used, which are used both in autonomous systems and in the mode of connection to the network. During the review of control methods for harmonic elimination, their different characteristics were noted, and the ad-vantages and disadvantages of each method were considered. Ref. 53, fig. 6.
