Clean Power Generation Technologies Thesis

Second, such fluctuations can be predicted accurately only a few hours to days in advance.Third, they are non-synchronous and use devices known as power converters in order to connect to the grid (this can be relevant in terms of how to ensure the stability of power systems).The concept of system effects, which are heavily driven by the attributes of VRE listed above, has been conceptualised and explored extensively by both the International Energy Agency (IEA) and the NEA along with research from academia, industry and governments.

Technology to utilise the forces of nature for doing work to supply human needs is as old as the first sailing ship.

But attention swung away from renewable sources as the industrial revolution progressed on the basis of the concentrated energy locked up in fossil fuels.

Wind turbines have developed greatly in recent decades, solar photovoltaic technology is much more efficient, and there are improved prospects of harnessing the energy in tides and waves.

Solar thermal technologies in particular (with some heat storage) have great potential in sunny climates.

The (WEO2016) makes the points that VRE have five technical properties that make them distinct from more traditional forms of power generation.

First, their maximum output fluctuates according to the real-time availability of wind and sunlight.

This was compounded by the increasing use of reticulated electricity based on fossil fuels and the importance of portable high-density energy sources for transport – the era of oil.

As electricity demand escalated, with supply depending largely on fossil fuels plus some hydro power and then nuclear energy, concerns arose about carbon dioxide emissions contributing to possible global warming.

There is a new focus on system costs related to achieving reliable supply to meet demand.

In the following text, the levelised cost of electricity (LCOE) is used to indicate the average cost per unit of electricity generated at the actual plant, allowing for the recovery of all costs over the lifetime of the plant.
