Move over Star Trek: Here comes Energy
By Elisa Wood September 22, 2010 Remember when the idea of generating electricity from wind turbines and solar panels seemed really cool? No denying their benefits, but they are sooo last year. Energy folks have gazed with envy at those who work in telecommunications for a long time. They invented the cell phone. Energy wanted its own thingamabob that would completely revolutionize its ...

Towards a model of wind energy industry development in industrial and emerging economies
Through the development and analysis of four in-depth case studies of the emergence of wind power industries in two industrialised and two emerging economies, the authors develop a model of sustainable energy industry development. The model demonstrates that fundamental economic indicators are insufficient for explaining new industry development. Environmental, institutional and cultural factors ...

The UK lags behind EU counterparts to achieve 20% renewable energy target
While some countries have almost hit their targets the UK still has a long way to achieve its 15% renewable energy target by 2020. The EU is more than halfway to reaching its 20% target of generating energy from renewables by 2020, according to new figures published today by Eurostat. The EU's 2009 directive on renewable energy set individual targets for all 27 member states, with a goal for the ...

Analysis of wind power in Danish electricity supply, 2005-2007
It is frequently said that wind power covers about 20% of electricity consumption in Denmark. The correct statement is that production of electricity by Danish wind turbines corresponds to about 20% of electricity consumption. A considerable fraction of the energy produced by wind turbines is exported to neighbouring countries and therefore is not used in Denmark. But how does one know that the ...

Multi-criterion optimization of energy management in drinking systems
In this study, two different energy sources that are connected to a pumped storage water supply system are analyzed: a water and a wind turbine. A water turbine can be integrated in a water supply system in high-pressure locations. Recently, new sources of energy production are being researched and applied due to the increase in the price of conventional energy sources and concerns regarding the ...

Productivity of small wind turbines for various wind potentials conditions: application in Bulgaria and Corsica
Less or more accurate power curve models are generally used to simulate the wind turbine electrical production versus the available wind speed. However, if such models are adapted to large machines, this is not the case for small ones. 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. An ...

Grid integration of renewables in Egypt - Case Study
Integration of large Amounts of Renewable Electricity in the Egyptian Energy Grid - Capacity Building for Management and Engineer-Technical Level (Egypt-RE-Grid). The electricity sector of the Arab Republic of Egypt produces large amounts of electricity through thermal and hydroelectric power stations. Egypt has diminishing proven oil reserves and declining production. Natural gas production is ...

The changing structure of the renewable industry – implications for a green transition to sustainable energy
This paper investigates the transition process from carbon to renewable energy. How a transition occurs, whose values are solicited and whose voices are listened to will determine the contours of the future economy. Section 1 will briefly discuss the current contours of global energy. Section 2 will discuss the large international oil companies (IOCs) as a possible obstacle to the transition to ...

A novel feed-forward and feed-back control of a VSI for variable speed wind-driven PM alternators
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 ...

Structure-preserving dynamical model and distributed stabilisation of electricity infrastructures with renewable energy resources
This paper introduces a module-based approach to modelling and controlling electricity infrastructure with a high penetration of distributed renewable energy resources. Each energy-converting component is defined as a module and is represented in terms of its local variables and the interaction variables between the module and the transmission network. The structure of the electricity ...

Renewable energy solutions: Necessity not choice
An elite gathering of Asia Utility firms speak out on the need to go Green. The Energy industry has become a key talking point globally. Renewable energy solutions are no longer optional but a necessity which must be embraced by all governments. Driven by China’s determination to reduce their dependence on coal energy and to look ahead to a more sustainable future, the recent NGU APAC summit ...

Integration of embedded generation in local grid using STATCOM
The renewable sources of energy are being connected to the local distribution system/local grid leading to embedded generation. As these sources are intermittent in nature, they impose technical challenges in the power system operation which include power quality related problems of local grid. The performance of the system has to be evaluated while connecting these sources to the local ...

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 ...
