A summary of wind power impacts on electric power system operating costs
Wind power plant output depends on wind speed. Such speeds cannot be accurately predicted over daily periods because the wind fluctuates from minute-to-minute and hour-to-hour. Consequently, electric utility system planners and operators are concerned that variations in wind plant output may increase the operating costs of the system. This concern arises because the system must maintain balance ...

Virtual Power Plant Ensures Optimum Energy Mix
For the management of its power plants, the utility company SaarEnergie is using a network control center from Siemens that simulates a virtual power plant. B ased in the German city of Saarbrücken, the utility company not only operates several power plants with a total capacity of about 2,000 megawatts; it also procures electricity from various distributed energy generation facilities such ...

Power curve measured and verified – Case Study
In 2010 RSE SpA (Energy System Research Inc.) within a Program Agreement with the Italian Ministry of Economic Development started a measurement campaign on a Libellula wind plant installed in Tuscany. The campaign lasted 1 ½ years and during this time RSE measured the turbine’s power curve following the requirements of the relevant IEC Standard ( EN 61400-12-1 – EN 61400-2). ...

Reducing avian collisions with wind turbines
Wind is an important renewable energy source for Europe. The wind power capacity installed in 2014 could produce enough electricity to meet over 10% of the EU’s electricity consumption. However, wind power structures can also be harmful to birds, which can collide with turbines. This study assessed methods of reducing avian collisions with wind turbines and makes several practical ...

ADMS 5 Buildings Validation Lee Power Plant Wind Tunnel Study
1 Introduction The Lee Power Plant wind tunnel study1 [1] featured releases from steam boiler stacks with a common height of 64.8 m affected by a building tier with a height of 42.6 m. The world's largest fluid modelling study chamber at Monash University in Australia was used for these experiments (see plan view in Figure 1). Stable meteorological conditions were simulated by using an inverted ...

Renewable Energy Systems - Case Study
Overview Generating renewable electricity is an important way to reduce carbon dioxide (CO2) emissions and many countries are installing wind and solar power plants to help meet targets for cutting CO2. One drawback of these energy sources is their variability: the wind tends to blow intermittently and solar power is only available during the daytime. Hence renewable power plants either have to ...

Wind Power Beats Nuclear Again in China
China, the country that is building more nuclear reactors than any other, continued to get more electricity from the wind than from nuclear power plants in 2014. This came despite below-average wind speeds for the year. The electricity generated by China’s wind farms in 2014—16 percent more than the year before—could power more than 110 million Chinese ...

Interview: CNPC on China’s gas developments & environmental policies
In this interview, conducted at Gastech, we had the pleasure of interviewing Shan Weiguo, Head of Gas Market Research at CNPC. We discussed China’s recent gas developments and its policies on lower emissions, energy security and the future of the country’s energy industry. Gastech News: What is your strategic view of gas development in China? Shan Weiguo: I believe that gas plays a ...

Aiming High Rewarding Ambition in Wind Energy - Report
EXECUTIVE SUMMARY With 392 GW installed, wind energy can be the single largest source of power generation in the EU by 2030 ahead of coal and gas. Wind energy already plays a significant role in the European power sector. In 2014, the wind industry installed 11,791 MW in the EU - more than gas and coal combined. Today wind energy can meet 10.2% of Europe’s electricity demand with a ...

Antarctica: a southern hemisphere wind power station?
The International Polar Year commences in 2007. We offer a macro-project plan to generate a large amount of electricity on the continent of Antarctica by using sail-like wind dams incorporating air turbines. Electricity can be used to make exploration and exploitation efforts easier on Antarctica. We offer the technical specifications for the Fabric Aerial Dam and indicate some of the ...

Rising offshore plant capacities lead to greater data-based O&M gains
The growing size of offshore wind farms provides greater scope for data optimisation during Operations and Maintenance, while software solutions can also help mitigate risk during the development phase, Marcus Ihle, Senior Consultant at Outsmart, said. Further gains could be made if operators share more data from their growing databases with other plant owners, Ihle said. The Levelized Cost of ...

US wind O&M thrust creates new roles, supplier networks
U.S. wind operators will invest in repowering, digital tools and remote technologies in the coming decade, supported by deeper service and spares networks, analysts and suppliers told New Energy Update. The phasing out of the U.S. federal production tax credit (PTC) is set to profoundly impact wind industry spending and employment trends. The 10-year PTC is set at $23/MWh for projects ...

Redefining Security for the 21st Century
By Lester R. Brown One of our legacies from the last century, which was dominated by two world wars and the cold war, is a sense of security that is defined almost exclusively in military terms. It so dominates Washington thinking that the U.S. foreign affairs budget of $701 billion in 2009 consisted of $661 billion for military purposes and $40 billion for foreign assistance and diplomatic ...

WOW: Solar without subsidies now also in Germany!
As announced in my blog of January 21, 2019 "We will abolish the EEG in 2019", the implementation and project planning of large PV systems without subsidies have now been officially announced. A historical development - the third pillar besides EEG and own consumption, "PPA" is the key word. We'll talk about that on February 26, 2019 in Berlin, more here . While around 2 GW of wind energy with ...

Ukraine spotlights German priority: energy switch
The crisis in Ukraine has added an extra dose of uncertainty to German Chancellor Angela Merkel's biggest domestic project: shifting the country from nuclear to renewable energy sources. Merkel launched the drive to transition the country away from nuclear after Japan's 2011 Fukushima disaster. Since then, the "Energiewende" - roughly, "energy turnaround" - has created increasing headaches. ...

Wind Energy Production Estimates: Moving Beyond Time Averages
No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

Wind Surpasses Nuclear in China
Wind has overtaken nuclear as an electricity source in China. In 2012, wind farms generated 2 percent more electricity than nuclear power plants did, a gap that will likely widen dramatically over the next few years as wind surges ahead. Since 2007, nuclear power generation has risen by 10 percent annually, compared with wind’s explosive growth of 80 percent per year. Before the March ...
