How to calculate the wind power abandonment rate

How to solve the problem of abandoning wind and PV power?

Calculation of renewable energy accommodation capacity is the basis to solve the problem of abandoning wind and PV power. Main problems of Chinese renewable energy accommodation is analyzed from power supply, power grid and load side aspects, and it focuses on the effect of inter-provincial tie-line to renewable energy accommodation capacity.

What is the problem of wind abandonment & PV abandonment in China?

In recent years, the problem of wind abandonment and PV abandonment in China has become increasingly prominent. In 2016, the amount of wind abandonment and PV abandonment exceeded 40 billion kWh . In 2017, the amount decreased slightly, but still very high.

What factors affect wind power accommodation capacity?

It is deduced that wind power accommodation is related to system operation mode, unit parameters and other factors. References [11, 12] study day-ahead assessment model of renewable energy accommodation capacity considering SCED model. This method is helpful to improve effectiveness and practicability of power grid dispatch planning.

Are wind and solar energy curtailments declining?

While a greater number of regions are experiencing some form of curtailment of wind and solar resources, the relative magnitude of curtailment appears to be declining in the largest markets for wind power even as the amount of wind power on the system increases.

What are Wind Energy Curtailment levels?

Curtailment levels have generally been 4% or less of wind energy generation in regions where curtailment has occurred. A notable exception is ERCOT, where curtailment levels reached 17% in one year, primarily because wind generation came online ahead of transmission capacity. These levels have since receded to less than 2%.

How are wind and solar compensation calculated?

The calculations used to assess compensation vary between wind and solar contracts. In general, wind payments are based on lost revenue (including electricity sales, PTCs, RECs). Solar compensation is based on the average generation over the same period before and after the incident.
