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 ...

Pumped hydro storage softens blow of wind imbalance penalties
Quarry Battery is developer of the £160 million ($249.2 million) Glyn Rhonwy pumped hydro facility in Wales which will be the UK’s first grid-scale electricity storage facility for decades. The facility will produce nearly 50 MW of electricity using pumped hydro technology. As more fossil fuel-fired generation is taken offline and wind capacity grows, grid operators will ask wind ...

How can we ensure the race for clean energy doesn’t leave the world’s poorest citizens behind?
As in other places around the world, Mexico’s wind boom runs the risk of bypassing the poor, which is why we need new global standards. Wind power is booming in Mexico. With more than 3,200 megawatts in operation, the country is on par with Japan. By 2018 it expects to have 10,000 MW installed as part of the government’s Climate Action Plan. Promising, right? Scratch the surface of ...

Renewable energy and the green economy: Green Energy and Green Economy Act, 2009
Ontario's Green Energy and Green Economy Act, 2009 (the 'Act') received Royal Assent on May 14, 2009. The Act's aim is to foster the growth of renewable energy projects, promote a green economy and energy conservation and to encourage the efficient use of energy. Its scope equals its intended impact on Ontario's energy sector: both are substantial. To realize its objects, the Act creates the ...

Wind power smoothing using rotor inertia aimed at reducing grid susceptibility
Due to wind speed variations, the output power of wind turbines fluctuates. These power fluctuations make the wind power undispatchable. Furthermore, they can cause frequency deviations and power outage particularly when wind power penetration is significant. This paper presents a novel control method to mitigate the power fluctuations using the rotor inertia as an energy storage component. ...

Dispatching of wind farms using battery energy storage
In this paper, a STATCOM interfaced battery energy storage system (BESS) is considered for smoothing intermittent power output of a large wind farm so that it can be dispatched. The main advantage of the system is that it can inject both real power (by charging/discharging the BESS) and the reactive power to the system. The paper investigates the main design issues related to BESS – the control ...

What is a renewable energy meter?
Renewable energy meter refers to the power meter that measures the situation of renewable energy generation. Different types of renewable energy generation require different measurement products, so renewable energy meters need to be customized according to the specific application requirements. Renewable energy includes solar energy, hydro power, wind power, biomass energy, wave energy, tidal ...

Generation Gap: Wind Opens Big Lead over Nuclear in China
In China, wind power is leaving nuclear behind. Electricity output from China’s wind farms exceeded that from its nuclear plants for the first time in 2012, by a narrow margin. Then in 2013, wind pulled away—outdoing nuclear by 22 percent. The 135 terawatt-hours of Chinese wind-generated electricity in 2013 would be nearly enough to power New York State. Once China’s ...

Global wind speeds bounce back to hike output; New Jersey raises offshore target to 7.5 GW
Global onshore wind speeds are rising, new study finds Global onshore wind speeds have risen since 2010, after decades of decline, boosting potential wind energy by around 17% between 2010 and 2017, according to a new academic study published in Nature. Rising wind speeds have increased U.S. wind turbine capacity factors by around 2.5% since 2010, representing half the gains in capacity ...

Measuring Offshore Wind Resources
To select the right offshore wind site, estimate the future energy output of a wind farm, and determine the best layout for the turbines, project developers must conduct wind resource assessment (WRA) campaigns on site. This is a critical phase of the successful development of wind farms. WRA campaigns on terrestrial sites have traditionally been performed using meteorological towers equipped ...
