"curtailment rate" is a correct and usable phrase in written English.
It refers to the percentage or proportion of something that has been reduced or cut back. Example: Due to the current economic situation, the company has implemented a 20% curtailment rate on all non-essential expenses.
We develop a flexible analytical framework and adapted the logarithmic mean Divisia index method to quantify the contributions of key factors in the change of wind curtailment rate.
As a consequence, not only are the benefits to both companies reduced, but the wind curtailment rate and carbon emissions are increased.
The average curtailment rate of wind and PV power and the average of start-up capacity of thermal power is presented in Fig. 5.
The comparison results are shown in Table 4, where BEW and BEC represent the wind power curtailment rate and total carbon emissions, respectively, calculated by (29), and Fig. 9 shows the curve of wind power accommodation.
Comparing the data presented in the last two rows of Table 4, it can be seen that utilizing P2G helps to reduce wind power curtailment rate greatly, from 25.01% to 14.03%, which enhances the rate of renewable energy accommodation.
In 2015, 15percentt of China's wind energy and nince percent of its solar energy was "curtailed," meaning that wind and solar energy production had to shut down because the electricity grid was not able to absorb the power that would have been generated (by contrast the curtailment rate in Europe is closer to one to two percent).
The respective integration requirements are quantified through storage and demand response utilization rates, VRE curtailment rates, non-VRE ramping requirements, system costs, and GHG emissions.
Due to Zambia's flexible hydro assets and potential pumped hydro storage capacity, large penetrations of centralized solar photovoltaic energy can be integrated with low curtailment rates, regardless of electric vehicle charging policy.
The high curtailment rates (>10%) and increased greenhouse gas emissions associated with non-export solar PV penetrations greater than 35% can be mitigated with flexible loads, such as electric vehicle charging, that is strategically shifted to coincide with high-resource periods of the day.
"Depending on who you talk to in the provinces that have by far the largest amount of solar production, curtailment rates are 30% and in some cases significantly higher than 30% - that's extraordinary and that's a real problem," explains Ball.
Curtailment rates for solar were not much better, with Gansu and Xinjiang recording solar curtailment rates of 31percentand26percentcent respectively (Chinese).
