Norway is hosting first-of-a-kind floating wind projects and opening up new sea areas for technology development, aiming to turn oil and gas know-how into renewable trade exports. Two recent announcements by Norway's government highlight the momentum gathering behind Norwegian floating wind development. In August, Norwegian state fund Enova agreed to fund NOK2.3 billion ($252 million) ...
Time-series energy modeling represents the next frontier of wind plant design and energy estimation. ...
Wind energy is soaring around the world, thanks to technology advances and energy policies that have reduced its cost. And things are only going to get better — with prices dropping substantially by mid-century, according to a survey of 163 of the world’s leading wind energy experts. The results, published in the journal Nature Energy, suggest that the cost of electricity from wind ...

2015’s official Wind Energy Forecast for the South African market was released today detailing the key market trends in 2015 for wind energy in in the country. Leading experts from Vestas, Siemens, Barclays, and Green Cape discussed key questions facing this year’s wind energy market inside the 8 page report. This January, experts from across the industry were asked five key ...
Offshore wind power installations are on track to hit a seventh consecutive annual record in 2013. Developers added 1,080 megawatts of generating capacity in the first half of the year, expanding the world total by 20 percent in just six months. Fifteen countries host some 6,500 megawatts of offshore wind capacity. Before the year is out, the world total should exceed 7,100 megawatts. Although ...
Sonoma Technology, Inc. (STI), with support from the Bureau of Ocean Energy Management, is leading a unique partnership of corporate, government, and university researchers to develop a marine environmental observations program in the Gulf of Mexico. The primary goal of this project is to develop a framework of advanced offshore measurements to support emergency response, oil and gas exploration ...
The impact of the wind generation on the power systems is no longer negligible if high penetration levels are going to be achieved. ...
The aim of this researcher is to develop a complete wind central model driven doubly fed induction generator (DFIG) which feeds an AC power grid. For that, two–pulse width modulated (PWM) voltage converters are connected back to back between the rotor terminals of DFIG and the utility grid via a common DC link, in there, our contribution will appear in the ...
This paper investigates the operation and control of multiple Distributed Generation (DG) systems interconnected to the utility in the form of microgrid. The developed model of the microgrid consists of microturbine generation system, converter-based DG system with stiff DC source, synchronous-generator-based DG system and wind power system with induction ...
This paper brings out an improved control strategy for an inverter employed to integrate a 3-kW wind-driven permanent-magnet synchronous generator (PMSG) to the utility network. The proposed controller features a feed-back control for enhanced current tracking performance and a feed-forward control for power tracking with varying wind-speeds. The harmonic content of the current fed to the grid is ...
This paper describes the analysis of near-surface wind speeds in Western Oklahoma. The goals of this research are to characterise the nocturnal low-level jet (LLJ) in the region, and to assess the impact wind variability, vertical shear and the LLJ on wind energy calculations. Results show the seasonal variability in wind characteristics as well as in the vertical wind shear, and also illustrate ...
The present paper deals with a developed and improved approach for exergy analysis of the wind. Based on this model, a typical wind turbine model (Bergey Excel-S) is assumed to be installed in two cities in Iran. The results show that, with regard to the annual average wind data, if the wind ...
In this paper Optimal Power Flow (OPF) problem is solved for a power system, which includes wind power as an additional generation input under variable load conditions. The fixed-speed Wind Turbine Generator (WTG) option is considered in this study: simulations have been performed for various sizes of wind farm attached to the IEEE 30-bus systems using the DIgSILENT Power Factory simulation ...
In order to linearise the SVC an established fourth order model is used and the development of more complex models is attempted. This study deals with the development procedure of two different high order models for the SVC. Finally, one of them is adopted along with the fourth order model in order to design two different ...
Today, there is a growing environmental concern about where the energy that we use comes from, bringing the attention on renewable energies. However, the use and trade of the renewable energies in the market seem to be complicated because of the lack of guarantees of generation, mainly in the wind farms. The lack of guarantees is usually addressed by using a reserve generation. The aggregation of ...
In this work, offshore wind power forecast and realisation data are combined with price information from the day-ahead market operated by the Amsterdam Power Exchange and from the imbalance market operated by the Dutch System Operator. This allows for computing spot-market revenues and imbalance penalties or gains for a wind power producer. Three different cases are evaluated: a perfect forecast, ...
There is a continuous discussion going on concerning the integration cost of wind power. The integration cost can, for example, be defined as the extra costs in the rest of the system when wind power is introduced, compared with the situation without wind power. ...
The realisation of two key energy policy goals pose significant challenges for power systems operation and control, namely electricity market liberalisation and increased penetration of renewable energy. This paper uses a case study analysis to explore solutions to these new challenges. The focus is on simulating real-time load management to maximise wind energy supply to a local authority ...
This paper introduces a computer-based model and dynamic simulation of a combined electro-mechanical control technique for a stand-alone wind turbine generator system. ...
This paper presents reactive power control of isolated wind-diesel-micro-hydro hybrid power system for realistic load disturbance using matlab/simulink. The mathematical model of the system based on matlab/simulink is developed. Reactive power control performance is compared using three different types of Static VAR Compensators (SVC). Transient responses for ...
