6 FAQs about [Wind power abandonment and thermal power generation plan]

Should wind power be abandoned?

Considering the cost of starting and stopping coal power units and the lower limit of output, a part of wind power needs to be abandoned to ensure the economy of the system. Scenario 2 transforms the coal power unit into the shunt carbon capture unit.

Is energy abandonment still a problem in 2021?

However, due to the intermittent and volatility nature of new energy output, the phenomenon of energy abandonment is still prominent. In 2021, the national abandoned wind power reached 20.61 billion kWh, and the abandoned photovoltaic power reached 6.78 billion kWh ( Li, 2022 ).

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.

How can bilateral transactions incentivize flexible loads to use more wind power?

Bilateral transactions can incentivize flexible loads to use more wind power by adjusting operating plans. The contract price of abandoned wind power in bilateral transaction depends on both the amount of surplus abandoned wind power generated by wind power company and the wind power utilization capacity of the load.

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.
