  • Research on intelligent charging method of electric vehicles based on virtual power plants   Order a copy of this article
    by Lianrong Pan, Jiayi Yang, Peikai Li 
    Abstract: The rising number of Electric Vehicles (EVs) requires new charging options to address grid integration and environmental concerns. Innovative charging methods are needed to reduce the burden on conventional infrastructure from electric automobiles. By applying these methods to VPPs, we can improve grid efficiency, electric car charging and energy sustainability. This research proposes the VPP-EV Charging Optimisation Framework (VPECOF) to evaluate the necessity and feasibility of an intelligent charging strategy for electric cars. A solution to the increased demand for electric vehicle charging infrastructure that meets grid stability and sustainable energy objectives is being developed using VPP technology and Smart Charging Optimisation Algorithms (SCOA). The suggested technique considers grid capacity, renewable energy availability and user preferences to improve charge schedules. This research simulates and analyses the intelligent charging strategy in the VPP framework, proving its efficacy and feasibility. The data may illuminate the benefits of synchronised electric car charging, such as peak demand reduction, grid resilience and renewable power integration. The study impacts transportation and energy regulators, utilities and stakeholders. The work improves electric car intelligent charging techniques and has consequences for their evolution.

    by Jinyin Peng, Xiangjin Zhu 
    Abstract: To improve the network security level of power market monitoring systems, this article optimised the structural scheme of a power market monitoring system from aspects such as physical environment, network access, and communication process according to actual application background conditions. To verify the reliability of the optimised power market monitoring system, this article conducted comparative experiments on the application of traditional power market monitoring systems and the proposed optimised power market monitoring system. Experimental verification found that the optimised power market monitoring system had a shorter system response time and faster data transmission speed compared with traditional power market monitoring systems. In the risk response assessment experiment, it showed an average improvement of 17.8% in four evaluation indicators. This article briefly discussed the problems that arise in applying traditional power market monitoring systems and proposed a solution for optimising network security based on cloud computing technology. The reliability of the optimised power market monitoring system was verified through experiments. Findings show that the optimised system achieved timely transmission and sharing of monitoring information, and improved accuracy and efficiency.

  • Condition monitoring and fault warning of a ground network of hydropower station based on power internet of things   Order a copy of this article
    by Renjie Liu, Zhiping Cheng, Haotian Wu 
    Abstract: This study proposed the Power Internet of Things and Deep Learning-assisted Condition Monitoring and Fault Detection Model (PIoT-DL-CMFD) for effectively monitoring faults in the ground network of hydropower stations. Data segmentation is used first to reconstruct the raw vibration data, which may enhance training efficiency. Secondly, Long-Short Term Memory (LSTM) can train the reconstruction data efficiently and adaptively under diverse operational conditions and fault factors. LSTM may then use network inference to detect the information fault classifications. Using the IoT, users can monitor storage conditions and control the devices by sending commands from any place in the world. The numerical findings illustrate that the recommended PIoT-DL-CMFD model enhances the fault prediction rate of 96.8%, accuracy ratio of 98.5%, overall performance ratio of 95.6%, water flow monitoring ratio of 94.5% and energy generation ratio of 97.2% compared to other popular methods.

  • Exploration and practice of energy efficiency under natural gas well drainage and gas production process method   Order a copy of this article
    by Chengxiang Yao, Haijian Li, Junhan Li, Yang Li, Yunjie Cai 
    Abstract: Natural gas, as a key fossil fuel, plays a vital role in the energy industry. This paper explores three drainage and gas production technologies foam drainage, beam pumping unit deep well pump drainage, and gas lift drainage with a focus on improving energy efficiency. By analysing experimental data, the study compares their performance in terms of cost and efficiency. At a drainage depth of 200 m, foam drainage was found to be the most cost-effective, reducing gas production costs by 170.02 yuan and 183.9 yuan compared to the other two methods. While energy efficiency among the three methods showed little difference, foam drainage is recommended for its lower cost, contributing to energy savings and technological advancement in natural gas production.

  • Utilisation of fuzzy logic control in self-healing of power systems: improved fuzzy C-means clustering method   Order a copy of this article
    by Zhongqiang Zhou, Jianwei Ma, Yusong Huang, Ling Liang, Zhiqi Chen 
    Abstract: This paper used a fuzzy logic controller based on an enhanced fuzzy C-means clustering method to address the current issues with power system self-healing. The augmented fuzzy C-means algorithm based on learning automata (LAFCMA) was produced by analysing the conventional fuzzy C-means algorithm (FCMA) and integrating and referencing the research methodologies of other academics. A Fuzzy Logic Controller (FLC) was built using LAFCMA, which enhanced the controllers clustering impact by analysing and grouping power data. The accuracy of using LAFCMA-FLC for power system fault detection was above 96.73%, and the average accuracy of detecting 20 fault points was 97.95%. The fuzzy logic control based on the improved fuzzy C-means clustering method had broad application prospects and research value in the self-healing of power systems. By achieving self healing of power systems, the frequency of manual intervention and maintenance can be reduced, thereby reducing operation and maintenance costs and improving economic benefits.

  • Dynamic response analysis and control of power systems by combining differential equation models with power data   Order a copy of this article
    by Jing Wang, Qiong Wang, Fangjun Li, Zhenfen Zhang, Jianyong Gao 
    Abstract: In response to the complex situation where the accuracy of describing the dynamic behaviour of the power system (PS) is low and the control strategy is difficult to cope with dynamic changes, this article combines differential equation models and power data to study the dynamic response analysis and control of the PS. Firstly, electricity data was collected from a certain power company, and the data was cleaned and standardised. Then, differential equation models were constructed for the generators, loads, and transmission lines in the PS, describing their dynamic behaviour and discretising the model. The MPC (Model Predictive Control) algorithm was used to define the objective function, set constraints, and solve the problem. The combination of differential equation modelling and MPC algorithm has improved the accuracy of describing the dynamic behaviour of the PS, and has good adaptability to complex dynamic changes, ensuring the safe and stable operation of the PS.
    Keywords: power system; power data; differential equation model; MPC algorithm; dynamic response analysis and control; description accuracy.

    by Xiaomeng Liu, Zuohu Chen, Wenlei Shi, Zhenguo Peng, Wenxia Li 
    Abstract: This paper combined differential equation models to study the dynamic modelling and prediction of power index data. Firstly, it collected electricity data from a certain power company from 1 June to 15 June 2023, and selected electricity index data to construct a partial differential equation model. The boundary and initial conditions were defined, and nonlinear effects and coupling relationships were established. Then, the least squares method and gradient descent algorithm were combined to estimate the parameters of the partial differential equation model. It then solved the model using the fourth-order Runge-Kutta method. Finally, based on the results of differential equations, this paper introduced the LSTM model for the dynamic prediction of power indicators. It demonstrates that the combined differentiable equation model-LSTM method performs well in power indicator prediction, enhances prediction accuracy, and guarantees steady power system operation. It also demonstrates a good capacity for capturing data changes in indicators.
