Increasing the integration of renewable energy in Northern and Central Europe markets is greatly influenced by the development of electricity transmission grid infrastructure. On the background of the fast development of offshore wind energy and its connection to the onshore electricity systems, a coordinated grid development in the North Sea may not only save costs for individual wind farms, but...
The use of renewable energy sources, such as wind power, is of major importance in future power grids for economic and environmental reasons, while the intermittent and stochastic nature of such energy brings challenges to system dispatch. Application of the virtual power plant (VPP) concept is one of the promising ways to improve utilization of renewable power. Among the many issues of practically...
Wind energy is a kind of renewable energy source with great potential. Besides, the wind technology is comparatively mature and the cost of the wind power generation is low. Since 2003, the Chinese government has implemented wind farm concession projects to gradually reduce the cost and grid price of wind power. Thus Chinese wind power can develop on a large scale. Until 2009, China has implemented...
With the rapid development of energy technology and the government's constant attention on the development and utilization of renewable energy, making use of clean and renewable energy power generation will be the future trend, and the wind power generation is a vital element. In this paper, we establish a multi-objective decision-making model for wind power projects evaluation based on analytic hierarchy...
The electrical energy storage systems serve many applications to the power system like economically meeting peak loads, quickly providing spinning reserve, improving power quality and stability, and maintaining reliability and security. The rapidly increasing integration of renewable energy sources into the grid is driving greater attention towards electrical energy storage systems which are capable...
The UK Government plans that offshore wind power should play a major part in meeting the UK's renewable energy and carbon emission targets by 2020. The pioneer UK Round 1 offshore wind farm projects, based on sites let in 2001, were supported by the UK Department of Trade and Industry's “Offshore Wind Capital Grants Scheme”. This paper reviews the economic and operational performances of those farms...
Transitioning to an infrastructure that integrates a more substantial portion of renewable energy sources into the larger energy portfolio is not effortless or without sacrifice; it has economic, technical as well as social challenges related to the decisions, choices and consequences in trying to establish new energy systems. Those decisions, choices and consequences are highly dependent on the social,...
Ensuring sustainable development conditions is presently world widely recognized as a critically important goal. This makes the use of electricity generation technologies based on renewable energy sources very relevant. Developing countries depend on an adequate availability of electrical energy to assure economic progress and are usually characterized by a high increase in electricity consumption...
RWE Innogy is developing a 750 MW offshore wind farm, Gwynt y Mor (GyM), 20 km off the north Wales coast and adjacent to the existing near-shore wind farms of North Hoyle and Rhyl Flats. This paper highlights some of the challenges faced in developing a large offshore wind farm in a climate of evolving renewable technology, challenging market conditions and a new GB regulatory framework for offshore...
The modern technologies used to generate electricity from renewable sources allow some control abilities of the production. These abilities can be required when the system is at risk by the System Operator. When facing a contingence, the System Operator could specify maximum values of renewable production in zones of the system. Delegated Dispatches of renewable production are zonal intermediate entities,...
