Affected by its control strategy, the output characteristics and fault characteristics of the inverter-interfaced distributed generations (IIDG) are different from those of synchro during the fault period, and the differential protection criteria applied to transmission lines cannot be directly transplanted into the distribution network. To solve the above problems, the fault characteristics of the inverter power supply are analyzed through the control strategy during the fault period, and a method to improve the sensitivity of line protection based on two-terminal dynamic impedance is proposed. The method uses the virtual part of the impedance of the two-end system and the line to construct the criterion, which avoids the influence of the traditional longitudinal differential protection on the current amplitude and phase relationship at both ends. Finally, PSCAD simulation software is used to build a 10 kV active distribution network model. The simulation results show that compared with the traditional current longitudinal differential protection, the proposed method has the advantages of high sensitivity, reliability, and strong resistance to transition resistance. © state Grid Electric Power 2025.

Sufficient treatment of industrial organic wastewater with high salt and large amounts of suspended particulate matter remains a challenge worldwide. In this work, a novel coagulation-flotation combined process was developed to treat the suspended particles as well as significantly reduce organic pollutants content in the actual high-salt organic wastewater. Four typical inorganic and organic flocculants (poly aluminum chloride (PAC), poly ferric sulfate (PFS), polyacrylamide (PAM), and modified cationic starch (CS)) were selected for compounding to obtain an optimized flocculation system for high-salt wastewater. The results showed that the PAC-PAM with a 10:1 ratio in mass exhibited the best coagulation behaviors with the removal efficiency of turbidity and chemical oxygen demand (COD) being 95.33% and 9.21%, respectively, under the optimal operation conditions, and the sedimentation process of coagulant conformed to the quasi-second-order kinetics. The PAC-PAM flocs exhibited stronger netting, sweeping, and adsorption bridging capabilities, which were conducive to removing suspended particles. When the flotation was conducted after coagulation, the COD decreased significantly by 20.82%. In addition, this combined process could reduce the treatment time by 50% compared to the process with only coagulation treatment. During the flotation process, floc particles companies with hydrophobic polycyclic aromatic hydrocarbons could collide and adhere to microbubbles and be floated to the surface, resulting in an effective reduction of COD. This work could provide a novel strategy and step forward to design and optimize the pretreatment process engineering for organic high-salt wastewater. © 2024 Institute of Process Engineering, Chinese Academy of Sciences.

Electric vehicles have the advantages of zero carbon emission, high energy efficiency and simple structure, and have been widely used today. Under the control of V2G, electric vehicles can be used as loads and distributed power sources, and become participants in the operation of auxiliary systems. Aiming at how to evaluate the load states and controllability of electric vehicle charging stations, this paper proposes a load sensing method for electric vehicle charging stations based on unsupervised learning and non-intrusive load monitoring. The proposed load sensing method firstly establishes the load sensing model according to the unsupervised learning strategy, and then uses the neural network model of the supervised learning strategy to evaluate the available regulation capability, so as to realize the load perception and regulation capability evaluation of the electric vehicle charging station. Through the verification of simulation data, it is proved that the proposed method has good performance in the evaluation of load perception and controllability of electric vehicle charging stations, which provides a feasible solution to the practical implementation of auxiliary responses by electric vehicles. © 2022 IEEE.

In recent years, with the rapid development of electric vehicles (EVs), the connection of a large number of EVs to the power grid has adversely affected the economic operation and system stability of the power grid. Therefore, research on the effective dispatch of EVs is of great significance. This paper proposes a day-ahead scheduling strategy for EVs based on converted economical objective, which makes full use of the flexibility of EV loads, takes into account the interests of the grid side and the user side, and reduces the negative impact of EVs connected to the grid. For the limitation of the objective function with the smallest variance, objective function converts the technical index of grid load peak-to-valley difference into an economic index with the smallest charging cost for users, and uses CPLEX to solve the day-ahead scheduling model of small-scale fast charging stations. The calculation example shows that this strategy can effectively reduce the peak-to-valley difference of grid load, which proves the rationality of the strategy. © 2022 IEEE.

Enhanced degradation and methane production of food waste anaerobic digestate using an integrated system of anaerobic digestion and microbial electrolysis cells for long-term operation

Environmental Science and Pollution Research 2024年第27期31卷 39637-39649页

The integrated system of anaerobic digestion and microbial electrolysis cells (AD-MEC) was a novel approach to enhance the degradation of food waste anaerobic digestate and recover methane. Through long-term operation, the start-up method, organic loading, and methane production mechanism of the digestate have been investigated. At an organic loading rate of 4000 mg/L, AD-MEC increased methane production by 3–4 times and soluble chemical oxygen demand (SCOD) removal by 20.3% compared with anaerobic digestion (AD). The abundance of bacteria Fastidiosipila and Geobacter, which participated in the acid degradation and direct electron transfer in the AD-MEC, increased dramatically compared to that in the AD. The dominant methanogenic archaea in the AD-MEC and AD were Methanobacterium (44.4–56.3%) and Methanocalculus (70.05%), respectively. Geobacter and Methanobacterium were dominant in the AD-MEC by direct electron transfer of organic matter into synthetic methane intermediates. AD-MEC showed a perfect SCOD removal efficiency of the digestate, while methane as clean energy was obtained. Therefore, AD-MEC was a promising technology for deep energy transformation from digestate. © The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.
