intermittent energy source造句

• Solar and wind are Intermittent energy sources that supply electricity 10-40 % of the time.
• The intermittent energy source combined with the nature of this mechanism make the engine naturally vibration-prone.
• The PPAs offer a high price equal to that of the load and an intermittent energy source on daily basis.
• Such " smart charging " could allow a utility to vary the electric charging load on its system in response to intermittent energy sources.
• An "'intermittent energy source "'is any source of energy or electrical power that is not continuously available due to some factor outside direct control.
• Thus, the plant will operate as an intermittent energy source while a plant with pondage can regulate the water flow at all times and can serve as a peaking power plant or base load power plant.
• Depending on these factors, beyond about 20-40 % of total generation, grid-connected intermittent energy sources such as photovoltaics and wind turbines tend to require investment in either grid energy storage or demand side management or both.
• Replacing existing air conditioning systems with ice storage offers a cost-effective energy storage method, enabling surplus wind energy and other such intermittent energy sources to be stored for use in chilling at a later time, possibly months later.
• The promised benefits include enabling the renewable energy industry to sell electricity to distant markets, the ability to increase usage of intermittent energy sources by balancing them across vast geological regions, and the removal of congestion that prevents electricity markets from flourishing.
• In an electrical power grid without energy storage, energy sources that rely on energy stored within fuels ( coal, oil, gas, nuclear ) must be scaled up and down to match the rise and fall of energy production from intermittent energy sources ( see load following power plant ).
