The estimation of in situ coal density has been the subject of extensive research due to its importance for coal reserve estimation. However, despite decades of studies, a universal method for density estimation that can be applied to all coal deposits still does not exist. Traditional ash-based methods are inaccurate because ash is a combustion product that …
The CVaR method is proposed to quantify the power shortage risk and power abandonment risk caused by the insufficient up and down spinning reserve (SR) capacity of the HTWPS. The coal consumption cost, the upper and lower SR cost and the tie-line cost are employed to characterize the economy of the HTWPS. (3) In order to enhance the peak …
