On the probabilistic distribution of wind speeds: theoretical development and comparison with data
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. Among the empirical correlations, the Weibull distribution has been most popular due to its ability to fit most accurately the variety of wind-speed data measured at different geographical ...

Wind energy generators sitting and sizing based on uncertain generation pricing
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. The uncertain generation directly impacts the network total generation cost and also the solution for the placement and sizing problem. So, this work takes into account this uncertain ...

Analysis and experimental verification of a control scheme for unified power quality conditioner
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. Based on the analysis a novel control scheme is established in a 2-phase Synchronous Rotating d-q Frame (SRF). In this control ...

Reactive power compensation of wind energy conversion system by using Unified Power Flow Controller
Voltage control and reactive power compensation in a distribution network with embedded Wind Energy Conversion System (WECS) represents the main concern of this paper. The WECS is a fixed speed/constant frequency system that is equipped with an induction generator driven by an unregulated wind turbine. The problem is viewed from short-term (10 seconds), mid-term (10 minutes) and long-term (48 ...

US plant shutdowns, grid focus drive storage growth: Greensmith CEO
Power plant closures and hiking transmission costs are driving up US utilities’ investment in renewable energy storage, John Jung, CEO of Greensmith, an energy storage services firm, told Wind Energy Update. Some 60 GW of US coal-fired capacity is set to close between 2012 and 2020, according to the EIA. Nuclear plant lifespans will end and the US plans $180bn in planned transmission ...

What is a renewable energy meter?
Renewable energy meter refers to the power meter that measures the situation of renewable energy generation. Different types of renewable energy generation require different measurement products, so renewable energy meters need to be customized according to the specific application requirements. Renewable energy includes solar energy, hydro power, wind power, biomass energy, wave energy, tidal ...
