With buildings accounting for high electrical demand and GHG emissions in Japan, enabling higher penetration of hybrid renewable energy systems can significantly reduce their load demand. This paper proposes an efficient power control scheme and design for a hybrid renewable standalone system...

We consider a farm of Kite Power Systems (KPS) in the field of Airborne Wind Energy (AWE), in which each kite is connected to an electric ground generator by a tether. In particular, we address the problem of selecting the best layout of such farm in a given land area such that the total...

The Wind energy is more reliable and speedier growing, among the renewable energy resources, due to the world environment challenges as well as increasing demand for energy. The wind turbine system's stability is cumbersome due to the uneven distribution of wind. Centrifugal and gravitational...

This paper aims to analyze the characteristic of wind speed data in Al-Salman site - Iraq using Weibull distribution. Maximum likelihood method (MLM) was used to find out two essential Weibull parameters. The best wind distribution was described by using probability density function and...

The research in this paper reveals how organising the innovation ecosystem can enable the achievement of the aim for innovation and competitiveness. The research was conducted from June 2014 to May 2015 using a qualitative deductive approach among operation & maintenance (O&M) actors in offshore...

Power in wind turbines are traditionally controlled by varying the pitch angle at high wind speeds in region 3 of the wind turbine operation. The pitch angles controllers are normally driven by electrical or hydraulic actuators. The motivation of this research is to design and implement a pitch...

In 2015, India set itself a very ambitious task of expanding its installed base of renewable energies by more than five times to 175 gigawatt (GW) within seven years (by 2022). It was envisioned that 60 GW would be contributed by wind power. In 2018, the objective was revised upwards to 227 GW...

The increasing construction of offshore wind farms and the expected improved profitability call for a better efficiency in offshore logistics. The purpose of this study is to propose scheduling and operations improvements for logistics to support offshore wind construction. The study conducts a...

We examine how different renewable energy support policies affect innovation in solar and wind power technologies. The analysis is conducted using policy and patent data for a large sample of 194 countries and territories. The policy data allows distinguishing two dimensions of regulation, i.e....

The energy needs of India have increased many folds in recent years due to industrialization and ever-increasing population. Wind energy offers excellent opportunities in fulfilling the energy needs of the country. Being renewable, it has enormous resource potential. Since the last decade, the...

Wind energy technologies are being developed in order to reduce the costs of the generated electricity and increasing technological performance. Therefore, understanding the technological development paths is an important part of the debates among technology developers and policymakers of energy...

Projektmanagement in der Windenergie -- Gesetzliche Grundlagen – der Katalysator für die deutsche Energiewende -- Typische Herausforderungen im Projektmanagement der Windenergiebranche -- Stakeholdermanagement in Projekten zur Errichtung von Windenergieanlagen -- Risikomanagement in Projekten...

This paper presents a hybrid wind generation with a doubly-fed induction generator (DFIG) and a permanent magnet synchronous machine (PMSM). The study analyzes the performances of the two wind systems and assets the stability of the operating parameters in the presence of a grid fault. Both the...

Fault-tolerable capability of Doubly Fed Induction Generator (DFIG) against disturbance occurrence is recognized as Fault Ride-Through (FRT). With quick and accurate compensation potentiality of Dynamic Voltage Restorer (DVR) to retrieve the nominal PCC voltage, DFIG can safely follow its normal...
