Abstract:This paper studies the control strategy of doubly-fed wind turbine to capture the maximum wind energy.The maximum wind energy capture is a more important part of the wind generation. Due to random fluctuations of the wind speed, to track the maximum power of wind turbine,we need to constantly adjust the speed of the generator, so that the generation run in the optimal tip speed ratio in different wind conditions,in order to achieve maximum power tracking.

The use of induction generators in wind power applications has been common since the early development of the wind industry. Most of these generators operate at fixed frequency and are connected directly to the utility grid. Unfortunately, this mode of operation limits the rotor speed to a specific rpm. Variable speed operation is preferred in order to facilitate maximum energy capture over a wide range of wind speeds.

Furthermore, it is not certain whether the value of K used in the standard control even provides for the maximum energy capture under real-world turbulent conditions.

In order to develop green energy, reduce carbon emissions, and alleviate global warming and the green energy crisis, many researchers focus on wave energy, using a device to convert wave energy into electricity. The three main types of wave energy converters are the overtopping type, the oscillating water column type, and the oscillating body type, and for most of them, the power generation efficiency is low. The research team in this paper proposed a wave energy converter for a wave-induced oscillation heave plate. The plate vibrates up and down under the action of waves, and the captured ene

Method of direct measurement of the capture neutron cross section for radioactive nuclei on the base of the multiplicity spectrometry of the capture gamma radiation was realized by means of the 4π-multisection detector. The energy of gamma rays of the radioactive irradiation must not exceed 1 MeV. Capacity methods had been examinated for the thermal neutron cross section measurement. Sensitivity for the minimum quantity of measured sample with capture cross section of 40 barns is equal to 0.37 mg, and maximum specific activity of the 137Cs in the measured sample is around 0.44 · 1010 Bk g-1.

Energy from wind is turning out to be a very promising alternative source technology in present and future power sector as it is environment-friendly and long-lasting with technological enhancements. Moreover, it occupies less space and has relative cost competitiveness. In the utility grid, the penetration of wind energy systems is expanding as the research progresses to capture greatest available wind power and operate the wind turbine (WT) with maximum possible aerodynamic efficiency. For this to accomplish a tracking controller is required to extract greatest wind power at all instants in

The use of renewable energy systems, specifically photovoltaic (PV) systems (PVs) that convert solar energy into electricity, has become a popular solution to address global environmental concerns by reducing the utilization of non-renewable energy sources, which contribute to pollution. Efforts to increase the power transfer effectiveness of PV systems include the advancement of controllers for maximizing power point tracking (MPPT). These controllers guarantee optimal system operation at the maximum power point (MPP) in diverse environmental conditions. The paper proposes an improved deep re
