“…For details, see Table 2. Table 2 Evaluation system of the utility of geological disaster prevention and control and geological environmental protection strategies A percentage system was implemented, and the linear weighted average method was used for the calculation of the scores [34][35]. Based on the calculation principles The index is scored according to the description of the index, and the score is written in the score column, and the full score of each level 2 index is 100.…”

Geological disasters in mines, ecological environment and geology and geomorphology are closely bound up with each other. To reduce or avoid economic loss and to decrease the threat degree of geological disasters to life safety, the protection of geological environment are formulated in this study. Specifically, this includes taking mines that are dominated by thin bedded carbonate as the research objects. The goals of this study include prevention and control of geological disasters and protection of geological environment. The data are based on characteristics of geological strata in mines collected by the exploration, and combined with the characteristics of geomorphic environment, relevant rules aiming at the prevention and control of geological disasters. Then, pursuant to the selection of indicators, an evaluation system is constructed to verify the effectiveness of measures and strategies proposed, in which the score value is converted into the corresponding level to test the implementation effect of the measures and strategies proposed. Through comparing the changes of the utility levels before and after the implementation of measures and strategies proposed, it can be seen that the geological disaster levels of the five mining areas in the study region are respectively improved from the non-ideal levels V, IV, V, V, IV to II, I, I, II, II, with the tailings pond leakage times less than 4 times and collapse volume less than 5m3. And, the levels of geological environment are upgraded from levels IV, IV, IV, V, V to ideal levels II, II, II, I, II, accomplished by the vegetation coverage rate of the mine reaching more than 35%, as well as the recovery rate of exploitation and utilization rate of tailings both exceeding 85%, which indicates that the protection strategy proposed in this paper has good practicality and feasibility.

“…Combining preventive control with transient stability, a transient stability preventive control (TSPC) is proposed to ensure that the system runs in a state that meets the requirements of transient stability (Yan et al, 2015). Literature (Xie et al, 2020) uses trajectory sensitivity to analyze the corresponding relationship between the trajectory changes of generator power angle and active power output and system stability to improve the transient stability of the system, but the process requires multiple time-domain simulation calculations and calculation time It is difficult to meet the requirements of online applications. Literature (Yousefian et al, 2017) uses a neural network model combined with short-term memory to determine the transient stability of the system.…”

“…Literature [3] studies the self-dispatch problems of price takers with wind power and thermal power production capacity with the aid of cyber-physical systems that support the power market manager decision-making. Literature [4][5][6][7] considers the impact of wind power consumption on the system. In response to the predicament of Northeast Power Grid peak shaving, this paper has proposed a dynamic paid peak-shaving benchmark based on load fluctuations, established a bidding mechanism which is conducive to market supervision, and finally established a multiobjective bidding dispatch model and peak shaving auxiliary service (hereinafter referred to as PSAS) market.…”

This article mainly analyze the shortcomings of the inherent peak shaving auxiliary service mechanism in the high-proportion of new energy access scenarios in Northeast China, which restricts the enthusiasm of thermal power units to participate in peak shaving. For this reason, a dynamic peak shaving compensation benchmark is proposed which follows load changes. At the same time, in order to standardize market behavior and facilitate market supervision, a guiding formula is proposed for quotation of thermal power units. Based on the above, a dynamic auxiliary service market mechanism is established which used actual operating data of Liaoning province power grid as a calculation example to verify that the mechanism can effectively improve the enthusiasm of thermal power units to participate in peak shaving, which is conducive to market operation and supervision as well.
