Invoices are the fundamental document that play a vital role in encapsulating the details of the products and the business transactions between the seller and the buyer. We cannot check our invoices at any time for emergencies. Substituting the case, by storing the basic details of multiple invoices in an excel sheet might be used for future purposes. This paper provides the advancement of data extraction through automation technologies. We begin this research by the technique Optical Character Recognition (OCR) in automation of data extraction from invoices. This reduces the manual errors during extraction as the entire process works with the automation and provides an accuracy of 95%. The paper discusses the design of the automation that has to be processed for the data extraction including the invoice details, line items and relevant metadata and stored in a structured and accessible format. This storage allows the customer to get through all their product details in a document. Furthermore, the study investigates the integration of extracted data from the invoice to the customer. This integration acts as the strategic role in transforming invoice data into a dynamic asset, enabling customers to glean insights. The paper incorporates real-world examples and case studies to illustrate implementations of scrapping techniques using automation. By addressing challenges such as technological limitations, integration complexities, and data security concerns, the paper provides practical understanding for customers in processing the automation. © 2024 IEEE.

In order to solve the problem of chaotic program formation in portable bionic robotic arms, which leads to excessive output angle of automation control methods and severe shaking during operation. A portable bionic robotic arm operation path automation control method based on single neuron PID is proposed. This method builds a hierarchical control structure for biomimetic robotic arms, dividing control tasks into multiple levels, and improving the overall flexibility and robustness of the system. At the same time, a single neuron PID algorithm is used to construct a job path controller, which takes the path position data generated by the bionic robotic arm as the control object. By simulating and setting the operation process of the bionic robotic arm, the output function sequence is reasonably arranged to achieve precise control of the end position of the robotic arm. The experimental results show that the proposed method has a control accuracy of no less than 90%, a task completion rate of over 97%, and higher control accuracy and higher operating efficiency of the robotic arm. © 2024 SPIE.

With the widespread application of non-stop power distribution network operations, traditional manual inspection and manual monitoring methods can no longer meet the needs of efficient and accurate safety assurance. To address this problem, this study proposes an automatic risk identification and early warning technology for non-stop power distribution network operations based on machine vision. Specifically, the YOLOv5 (You Only Look Once version 5) algorithm is used to detect the targets of workers and safety protection equipment, and to identify the wearing status of workers' safety protection equipment in real time. The U-Net image segmentation algorithm is then used to accurately identify the insulating shields and safety areas in the working environment. Next, multi-task learning and data enhancement methods are used to improve the robustness and recognition accuracy of the model under different lighting and scenes. Finally, through the integration of video surveillance and risk warning modules, combined with virtual electronic fence technology, the system can automatically identify the illegal behavior of operators and trigger immediate alarms. Experimental results show that the accuracy of the YOLOv5 model can reach up to 93% under strong light conditions;the U-Net model can effectively detect and identify non-compliant occlusion operations when detecting obstructions;and the accuracy of out-of-bounds behavior detection in simple daytime scenarios can reach up to 95%. From the above data conclusions, the combination of YOLOv5 algorithm and U-Net algorithm can not only automatically identify security risks, but also provide real-time and accurate early warning support in complex environments, which has broad application prospects and promotion value.

In order minimize power variations caused by erratic wind energy output, this research proposes a hybrid energy storage system that combines supercapacitors and all-vanadium liquid batteries. The grid-connected and varying wind power is precisely calculated using an adaptive sliding average approach. We used Tuna Swarm Optimization (TSO) to optimize the Variational Mode Decomposition (VMD) parameters in order to minimize subjectivity in parameter definition. Grid stability is increased by 34% and wind fluctuations are decreased by 40% with the enhanced technology. Furthermore, a fuzzy control mechanism modifies the storage components' state of charge (SOC) between 10-90%. This approach improves the stability of the electricity system, according to empirical data. © 2024 IEEE.

The key to solving the power quality problem of the traditional traction power supply system was the through-connected traction power supply system. This study analyses the impact of the traditional through-connected traction power supply system on power quality and constructs a new through-connected traction power supply system that considers the improvement of power quality and multi-energy access. This is achieved by combining the multi-energy access scheme. A comparative analysis is conducted between the new system and the traditional through-connected traction power supply system in terms of four aspects: power quality, multi-energy access, economy and low-carbon, and stability and flexibility of the system. The results show that the advanced traction power supply device considering power quality improvement and multi-energy access has positive effects in facilitating new energy consumption, effective harmonic suppression, and cost optimization. © Published under licence by IOP Publishing Ltd.

In this study, the smoothing reactor and DC filter of a DC transmission line are found to significantly attenuate the high-frequency components of the transient signal through simulation and analysis of internal and external faults of high-voltage direct current (HVDC) transmission lines. Consequently, the time-domain waveforms of the voltage fault component at the measurement end of transmission lines differ significantly among different fault types. When an external fault occurs, the high frequency component is low and the waveform is smooth, while when an internal fault occurs, the high frequency component is high and the waveform is steep. A multifractal spectrum is calculated based on the curvature characteristic value K-max of the multifractal spectrum that measures the irregularity of the voltage fault time-domain waveform. If the external fault occurs, K-max is greater than 10, and if the internal fault occurs, K-max is less than 10. Simulation tests with PSCAD demonstrate that this criterion is highly reliable, does not depend on fault location, and is resistant to transition resistance.

Voltage and reactive power control via inverter-based distributed generators is necessary for distribution power network to mitigate voltage violations. Voltage control is vital to keeping distribution power system voltages within normal range, minimizing power network losses and reducing losses of voltage regulating devices. To deal with incomplete and inaccurate distribution power system models, voltage control problems are solved in a model-free way by using a multi-agent deep reinforcement learning algorithm(DRL). The voltage control problem has been transformed in power system into an deep Q-network(DQN) framework, which avoids solving a specific optimization model directly due to time-varying operating conditions. The designed reward function guides these agents to interact with the distribution power system in the direction of normal voltage interval. © 2024 Technical Committee on Control Theory, Chinese Association of automation.
