Can you guess which country it is? WEIBULL DISTRIBUTION The information about the frequency of occurrence of certain wind speed events is captured by the histogram, also called the wind distribution. ...
In wind energy projects, obtaining precise and reliable wind resource data is crucial, yet the available data often remains limited in both time and space. To extend this data into the long term, integrating real-world measurements with model results becomes essential. This study demonstrates the process of improving modelled turbulence using observational data and calibrating high-resolution ...
It is suitable for wind power generation in open plains, islands, coastal areas, etc. The power generated by small-scale wind turbines for household use is about AC 13V~25V. ...
Emerging economies require more power, every hour, not just when the sun shines or the wind blows, but all the time — reliably, economically, and cleanly. But the world will no longer finance fossil fuel baseload power plants. What to ...
Therefore, a high efficiency high frequency transformer should have low DC loss and AC loss, low leakage inductance, small distributed capacitance of winding itself and small coupling capacitance between windings. ...
Below, we illustrate Germany’s position on energy storage batteries, given it is a country with a high level of renewable power (27.3% of national energy mix (2014), according to german think-tank Agora Energiewende. Call for more Distributed Wind? Distributed Wind is typically a single or small number of ...
Wind energy is one of the developing resources of renewable energy. In order to increase the use of wind energy, development of wind turbine blade with higher power coefficient plays a vital role. ...
Influence of exogenous and endogenous factors on the exergy analysis of 3 column array wind farm for two different layouts are highlighted in this paper. Nine turbines were placed in two different layouts to analyse the influence of exogenous factors such as wind velocity, wind direction, wind distribution and ...
When an internal fault occurs in a synchronous generator, the symmetry between the parallel paths of the winding is broken and different currents flow in them, due to unsymmetrical magnetic linkage between the stator windings. ...
The objective of this paper is to study the impact of different small-scale wind turbines power curves and wind distributions on the electrical production. ...
This paper proposes a methodology for sitting and sizing wind distributed generators (WDGs). These generators are characterised by an uncertain active power production due to the random behaviour of the wind speed. ...
Many bridges are located at especially unfavourable places considering the local wind power and turbulence. Therefore it turns out that finding an optimal balance between structural safety and erection costs depends strongly on a proper wind modelling and investigation. Several aspects must be taken into account for the wind design. The effect of ...
In addition, expect to see a lot more solar panels and small wind turbines powering stores and offices very soon as a result of significant tax credits and loan guarantees. The stimulus funds should lead to 121 MW more of solar units on commercial buildings by 2011, a 15% jump, and 120 MW in distributed wind turbines by 2016, a 527% jump. ...
The operation of wind turbines has an impact on the power quality at the connected electric network. The integration of wind electric generators with the power grid becomes a headache for power engineers in several aspects. ...
The paper summarises the refereed contributions of seven articles reviewed for publication in the IJETP – Special Issue on "Reactive compensation for wind farms". The main goal of the special issue is to provide a forum to exchange information on the reactive power compensation requirements for wind farms and introducing possible price mechanisms for today's ...
Voltage control and reactive power compensation in a distribution network with embedded Wind Energy Conversion System (WECS) represents the main concern of this paper. ...
This paper studies the impact on the voltage profile of wind energy based generators connected to distribution power systems. ...
Improving power quality for sensitive load by a Unified Power Quality Conditioner (UPQC) in a distributed generation system is presented in this paper. The power balance of a UPQC, consisting of back-to-back connected series and shunt Active Filters (AF), is analysed. ...
The probabilistic distributions of wind speed are a critical piece of information needed in the assessment of wind-energy potential, and have been conventionally described by various empirical correlations. ...
In this paper, a method is established where the roughness length of the ocean is calculated from the wind speed and the fetch length. The fetch length depends on the wind direction and a case study is performed for a wind turbine exposed to wind blowing in two opposite directions: from the shore and the sea. For each case, the ...
