New Energy Wind Power and Photovoltaic Power Generation

How will solar PV & wind impact global electricity generation?

The share of solar PV and wind in global electricity generation is forecast to double to 25% in 2028 in our main case. This rapid expansion in the next five years will have implications for power systems worldwide.

Why do we need a forecast for wind and photovoltaic power generation?

The ability to forecast wind and photovoltaic power generation in advance provides valuable insights for grid operators, energy traders, and renewable energy system planners . Accurate forecasts enable efficient load balancing and support decision-making processes related to energy storage and backup generation.

Can wind and photovoltaic power generation be combined?

However, the integration of wind and photovoltaic power generation through combined forecasting offers a comprehensive approach that takes into account their coupling relationship. By establishing suitable models and algorithms, accurate power generation forecasts for both energy sources can be achieved.

Why is wind and solar energy a natural product?

However, wind and solar energy, as a natural product, are greatly affected by natural environmental factors, which makes wind and photovoltaic (PV) power generation have strong randomness, volatility and discontinuity, resulting in unstable power generation and low energy conversion efficiency .

What is the power-use efficiency of PV and wind power plants?

By considering the flexible power load with UHV and energy storage, the power-use efficiency for PV and wind power plants is estimated when the electrification rate in 2060 increases from 0 to 20%, 40%, 60%, 80% and 100% (a) and the power generation by other renewables in 2060 increases from 0 to 2, 4, 6, 8 and 10 PWh year −1 (b).

How are PV and wind power plants estimated?

The installed capacity (a) and costs (b) of PV and wind power plants built during 2020–2060 are estimated in our model by optimizing the construction time of individual power plants at a temporal interval of 5 years (bars) or 10 years (stars).
