Wind power and photovoltaic power generation consumption warning

How to achieve wind and PV power consumption in China?

The method for achieving wind and PV power consumption through the peak-load regulation capacity of the power grid, after their integration to the grid, is the most popular strategy in China. The key factor that determines how much wind and PV power can be consumed by a power grid is the peak-load regulation capacity of a power grid.

What factors affect the utilization of wind and PV power?

In addition to the influence of variation characteristics of the output on its comprehensive utilization, another important factor affecting the utilization of wind and PV power is the spatial mismatch between the power generation capacity and the power demand capacity.

What is the rate of abandoned wind and PV power?

For example, in recent years, the amount of abandoned wind and PV power has been decreasing year by year. In 2019, the rate of abandoned wind and PV power accounted for less than 4% of the total wind and PV power generation .

What are the causes of wind & PV power abandonment problems?

Additionally, several situations, including power generation aspects (e.g., unstable power supply, imbalance of supply and demand) and power grid aspects (e.g., power grid constraints, storage of transmission lines, and scarce capacity of peak shaving), have resulted in serious wind curtailment and PV power abandonment problems .

Is there a correlation between PV power production and wind power production?

For the majority of weather patterns, we see an anti-correlation between the European mean of the PV power production and wind power production, i.e., weather patterns associated with positive anomalies in wind power production typically coincide with negative anomalies in PV power production and vice versa (Fig. 2 ).

Are there anomalies in PV and wind power production?

We consider anomalies in terms of power production and do not simulate electricity demand or transmission. However, over- and underproduction would theoretically correspond to an over- or undersupply, if all else was equal. We assess anomalies in PV and wind power production associated with different weather patterns.
