Aiming at tlie cliaracteristics of liigli reliability, long-life equipment or newly developed equipment with a small number of failure degradation data samples, this paper proposes a method for predicting the remaining useful life of equipment systems based on the fusion of support vector regression (SVR) and drift Wiener process. Firstly, the distribution function of the drift Wiener process is transformed;then, a support vector regression machine method is introduced to establish an optimization model to estimate the parameters of the drift Wiener process, and a life prediction algorithm based on SVR and drift Wiener process is researched and established. Finally, a certain highly reliable and long-life cabin environment system is used as an example to carry out life prediction. The application shows that the method proposed in this paper has better prediction than the traditional maximum likelihood estimation method and moment estimation method in a small sample. © 2021 IEEE.

Energy storage station (ESS) and wind farm (WF) have the potential to serve as a black-start sources to accelerate the power system restoration after blackout. However, the voltage security problem when start the auxiliary machines of power plants limit their reliability as black-start sources. A voltage control method is proposed for ESS and WF combined black-start sources to improve the voltage security during black-start. Firstly, the black-start process based on grid-forming ESS and WF is presented, and the voltage control framework is established. Then, a predictive control method considering the impact of active power on voltage variations is proposed, in which different optimization modes are established to obtain the active and reactive control sequences for WF and ESS. Finally, black-start simulation with Matlab/Simulink demonstrate the proposed method can improve the voltage security level when starting auxiliary machines of power plants. © 2024 IEEE.

Under the current inter-provincial tie-line power assessment mechanism in China, regional power grids typically return assessment fees to each province based on their relative tie-line and frequency control performance. However, under this return method, if all provinces in a regional grid perform poorly in frequency regulation capacity, the returned control performance standard (CPS) fines for each province will be close, resulting in a lower penalty for power and frequency over-limit violations on provincial grid interconnections. To simulate and compare the decision-making of provincial dispatch and control centers regarding automatic generation control (AGC) adjustable capacity under different CPS assessment fee return methods, this article proposes a two-province game model. In this model, the two provinces follow best response dynamics for alternating frequency regulation simulation and scheduling optimization until a balance is reached or the variation in reserve capacity is within a certain range. Testing different combinations of assessment prices and return methods, the results show that determining and announcing the provinces to receive fine returns based on their ranking in assessed electricity quantity can better motivate provinces to improve frequency regulation performance. © 2024 IEEE.

Unlocking the electrocatalytic activity of natural chalcopyrite using mechanochemistry

Manipulating the structure self-reconstruction of transition metal sulfide-based(pre)catalysts during the oxygen evolution reaction(OER) process is of great interest for developing cost-effective OER catalysts,which remains a central challenge. Here we realize a deep structure self-reconstruction of natural chalcopyrite to unlock its OER performance via mechanochemical activation. Compared with the manually milled counterpart(CuFeS_(2)-HM), the mechanically milled catalyst(CuFeS_(2)-BM) with a reduced crystallinity exhibits a 7.11 times higher OER activity at 1.53 V vs. RHE. In addition, the CuFeS_(2)-BM requires a low overpotential of 243 mV for generating 10 mA cm^(-2) and exhibits good stability over 24 h. Further investigations suggest that the excellent OER performance of CuFeS_(2)-BM mainly originates from the decreased crystallinity induced the in situ deep structure self-reconstruction of the originally sulfides into the electroactive and stable metal(oxy)hydroxide phase(e.g., a-Fe OOH) via S etching under OER conditions. This study demonstrates that regulating the crystallinity of catalysts is a promising design strategy for developing highly efficient OER catalysts via managing the structure self-reconstruction process, which can be further extended to the design of efficient catalysts for other advanced energy conversion devices. In addition, this study unveils the great potentials of engineering abundant natural minerals as cost-effective catalysts for diverse applications.
