A virtual power plant is a system that integrates several types of power sources, (such as microCHP, wind-turbines, small hydro, photovoltaics, back-up gensets, batteries etc.) so as to give a reliable overall power supply.〔(Feasibility, beneficiality, and institutional compatibility of a micro-CHP virtual power plant in the Netherlands )〕 The sources are often a cluster of distributed generation systems, and are often orchestrated by a central authority. An example of a real-world virtual power plant is found on the Scottish Inner Hebrides island of Eigg.〔BBC Radio 4. Costing the Earth- Electric Island〕 ==Overview== The concerted operational mode delivers extra benefits such as the ability to deliver peak load electricity or load-aware power generation at short notice. Such a VPP can replace a conventional power plant while providing higher efficiency and more flexibility. Note that more flexibility allows the system to react better to fluctuations. However, a VPP is also a complex system requiring a complicated optimization, control, and secure communication methodology.〔(Smart Grid - The New and Improved Power Grid: A Survey ); IEEE Communications Surveys and Tutorials 2011; X. Fang, S. Misra, G. Xue, and D. Yang; .〕 According to a recent report from (Pike Research ), the VPP market will continue its steady growth over the next several years, increasing from $5.2 billion in worldwide revenue in 2010 to nearly $7.4 billion by 2015, under a base case scenario. In a more aggressive forecast scenario, the clean tech market intelligence firm forecasts that global VPP revenues could reach as high as $12.7 billion during the same period. "Virtual power plants represent an ‘Internet of Energy,’" says senior analyst Peter Asmus of Pike Research. "These systems tap existing grid networks to tailor electricity supply and demand services for a customer. VPPs maximize value for both the end user and the distribution utility using a sophisticated set of software-based systems. They are dynamic, deliver value in real time, and can react quickly to changing customer load conditions." The concerted operational mode delivers extra benefits such as to the ability to deliver peak load electricity or load-following power at short notice. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「virtual power plant」の詳細全文を読む スポンサード リンク
