Wind energy has become a large contender of traditional fossil fuel energy, particularly with the successful operation of multi-megawatt sized wind turbines. However, reasonable wind speed is not adequately sustainable everywhere to build an economical wind farm. In wind energy conversion systems, one of the operational problems is the changeability and fluctuation of wind. In most cases, wind ...

The increasing concern of global climate changes, the promotion of renewable energy sources, primarily wind generation, is a welcome move to reduce the pollutant emissions from conventional power plants. Integration of wind power generation with the existing power network is an emerging research field. This paper presents a meta-heuristic algorithm based approach to determine the feasible dispa...

A large amount of wind power has to be curtailed due to the inflexibility of the combined heat and power (CHP) system in the heating season in northern China. The power-to-gas (P2G) technology, which uses electricity to produce hydrogen or synthetic natural gas, has become a promising energy conversion option for the utilization of surplus power energy. In this paper, an integrated natural gas,...

Wind power systems have strong nonlinear characteristic, when wind speed is below the rated value. A novel intelligent hybrid maximum power point tracking (MPPT) controller for variable-speed wind power systems is designed, linear parameter-varying (LPV) gain-scheduling controller is designed to regulate output of fast-dynamics generator torque, neural network compensator is used to eliminate t...

Wind power has been widely considered in recent years as an available and a clean renewable energy source. The cost of wind energy production is currently the main issue, and increasing the size of wind turbines can reduce wind energy production costs. Hence, megawatt wind turbines are being rapidly developed in recent years. In this paper, an aerodynamic analysis of the NREL 5MW turbine is...

Main objectives of the paper were to examine the complementary nature of solar and wind energy in primary and in “useful” form. Analyses are performed on real, measured solar and wind potential data at the same site. Solar irradiation and wind power density have been assessed as primary forms. In order to examine effects of their complementarity in real applications, i.e. in power systems, a hy...

─The purpose of this study was to explore the related practical techniques of monitoring and controlling system in designing renewable energy system, especially for Small-scaled wind-power generator. Recently, the whole world was actively developing replaced energy to solve the economic development and daily-life necessities problems resulting from gradually lacking of oil. Taiwan government wa...

The IEA WIND Task 25 also known as the " Design and Operation of Power Systems with Large Amounts of Wind Power " , Task 25 of IEA Implementing Agreement on Wind Energy, functions within a framework created by the International Energy Agency (IEA). Views, findings and publications of IEA WIND Task 25 do not necessarily represent the views or policies of the IEA Secretariat or of all its individ...

After tremendous growth of wind power generation capacity in recent years, China now has 44.7 GW of wind-derived power. Despite the recent growth rates and promises of a bright future, two important issues the capability of the grid infrastructure and the availability of backup systems must be critically discussed and tackled in the medium term. The study shows that only a relatively small shar...
