01 Jan 2019TL;DR: An analytical study on various frequency adjustment mechanisms for a grid-connected wind farm and strategy of frequency adjustment is developing time to time which starts from using droop controller based Induction generator to converter based Double-fed Induction generators.
Abstract: Continues expanding of wind power harnessing demands an effective control system to improve quality power delivered from wind turbine to grid. A stable power system fully depends on the synchronization that means matching of frequency between the source of power generation and existing power grid. The prime objective of a wind farm controller is to ensure effective operation of the wind farm in any wind speed condition. Frequency deviation between the wind system and grid can challenge the well-built operation of a power system and can imbalance the synchronization between wind farm and grid. The strategy of frequency adjustment is developing time to time which starts from using droop controller based Induction generator to converter based Double-fed Induction generator. This paper summarizes an analytical study on various frequency adjustment mechanisms for a grid-connected wind farm.

TL;DR: In this paper, X-ray diffraction (XRD) patterns showing sharp peaks confirmed the formation of single phase cubic spinel structure and lattice parameters of the samples were determined from the XRD data using Nelson-Riley extrapolation technique.
Abstract: Abstract Polycrystalline Cr substituted Ni ferrites [NiCrxFe2−xO4 (0.0 ≤ x ≤ 1.0)] were synthesized by conventional ceramic method and sintered at 1350 °C in air. X-ray diffraction (XRD) patterns showing sharp peaks confirmed the formation of single phase cubic spinel structure. The lattice parameters of the samples were determined from the XRD data using Nelson-Riley extrapolation technique. They were found to decrease with increasing Cr concentration obeying Vegard’s law. X-ray density, bulk density and porosity were also calculated from the XRD data. The variation of DC resistivity with temperature was measured by two-probe method. The DC resistivity was found to decrease with increasing temperature indicating the semiconducting nature of the samples. Activation energy was calculated from the Arrhenius plot. AC resistivity, dielectric constant and loss tangent were measured in the frequency range of 1 kHz to 120 MHz at room temperature.

TL;DR: In this paper, the authors analyzed the spatiotemporal data of electric power generation mix and cost and revealed electricity cost of per unit varies with consumer and distribution line Voltage and showed future of electric generation mix (renewable energy, coal and uranium) is best option for the large capacity power plant in Bangladesh to satisfy electricity demand.
Abstract: Bangladesh is a developing country and over populated nation using electricity 80% of people. Electricity demand is gradually rising day by day. Electric power generation-mix is share sources from where electricity produces. Generation sources are significant for the country those depend on geography, demography, environment and economics. So, natural gas is large share in electricity generation mix in Bangladesh. Respectively other sources like oil, coal, hydro, renewable energy are contributed for generating electricity. In future, renewable, coal, uranium will be more in generation share. The cost of electricity depends on economic and market of country. In this paper, spatiotemporal data of electric power generation mix and cost are analyzed and revealed electricity cost of per unit varies with consumer and distribution line Voltage. The analysis of this paper shows future of electric generation mix (renewable energy, coal and uranium) is best option for the large capacity power plant in Bangladesh to satisfy electricity demand.
