Sentences with phrase «intermittent generation sources»

Longer duration energy storage solutions are expected to become more important as more intermittent generation sources, such as wind and solar power, come onto the grid.

As the amount of wind generation increases, electric power system operators have faced challenges with integrating increasing amounts of this intermittent generation source into their systems.

Not exact matches

But keeping those lights on amid ever increasing demand and the rise of wind, solar and other alternative sources of electricity generation that are inherently intermittent is just one of the goals of a smart grid.

Therefore, power generators and grid operators need back - up capacity that can fill the generation gap that results when these intermittent sources are unavailable and that also can be scaled back when intermittent sources are generating power.

However, replacing these power sources with wind and solar farms requires megawatt - level storage capacity to buffer the intermittent generation from these renewable sources.

Unlike most generation sources, wind has a fatal flaw: it is both intermittent and unpredictable.

With liberalization of the electricity market and expansion of renewable sources, distribution grid mandates have mounted, requiring, for example, that operators ensure their grids remain stable despite increased levels of intermittent generation.

For example, if grids can't be adjusted to deal with intermittent supply from renewable sources like wind, that makes these sources more expensive — and potentially reduces their EROI if a lot of gas - fired power is needed for backup generation.

I suspect that, in practice, fridges and freezers will be useful for balancing the short term fluctuations in generation from sustainable sources such as solar photovoltaics affected by intermittent cloud cover while water heating, electric car charging, and municipal water pumping will more nearly match the time spans involved in wind farm generation.

Natural gas will reap $ 804 billion, bringing 16 percent more generation capacity and making the fuel central to balancing a grid that's increasingly dependent on power flowing from intermittent sources, like wind and solar.

Therefore, intermittent renewables are not a suitable source of power for pumped hydro, except in a few special, extraordinary cases --(such as El Heiro island where they have a 700 m high extinct volcano crater providing a large upper reservoir, good wind resource and are replacing high - cost diesel generation.)

For example, utility - scale wind generation, a particularly volatile intermittent power source, requires electricity operators to make significant adjustments to balance generation and load, creating inefficiency in the system.

The green proposition of electric cars, especially the plug - in variety, is that by promoting the development of electricity generation and energy storage technology development (in the form of energy storage devices such as batteries), electric cars are not only reducing the need for gasoline, but also creates pull factors for the development of grid - connected renewable energy sources such as solar and wind energy by creating new electricity demand and provide energy storage solutions to address the problems of the intermittent nature of solar and wind power.

The added costs imposed by intermittent energy sources like wind energy include the displacement of lower cost generation (e.g., natural gas), requirement of dispatchable backup generation, reduced capacity factors for conventional generation, increased electric price volatility, and decreased system efficiency.

Storage is Still # 1 Thing to Figure Out While this high electricity generation from a very clean source is great news, it is also a good reminder that intermittent and variable sources of power pose a great challenge to the grid.
