As the scale of the power system enlarges, the current system of collecting power consumption information has the disadvantages of delays in transmitting information, excessive bandwidth pressure, and the lack of real-time information processing capability. In order to alleviate the aforementioned issues, this paper provides an edge computing method to enhance the system of collecting power consumption information. the edge computing concept is to execute the preprocessing, analysis, and decision-making functions of the data near the source end at the edge nodes to decrease the center server load and enhance the real-time nature and reliability of the system. this paper initiates the explanation of the use cases of edge computing to collect power consumption information and verifies the optimization strategies of edge computingthrough specific examples. In practical use cases, edge nodes execute functions such as anomaly detection of power consumption and fault alarms through real-time monitoring and analysis of the information, significantly decreasing the amount of transmitted information and the system's response time. the results prove that the edge computing optimization strategy has superior performance in the efficiency of transmitting information, the ability to process real-time information, and system stability, providing a new technical means to the intelligence and efficiency of the system of collecting power consumption information.

this study conducted an in-depth discussion on the intelligent scheduling and optimization algorithm of mobile nursing. By constructing an optimization model for cost minimization and resource maximization utilization, combined with heuristic algorithms, the scheduling efficiency and resource utilization were significantly improved. Specifically, through strategies such as parameter tuning, heuristic improvement, and parallel computing, the optimized algorithm performs well in key indicators such as cost control, resource consumption, and task completion time. Experimental results show that the optimized algorithm can maintain good performance under different task loads, especially under high load conditions. through real data set testing, the robustness and broad applicability of the algorithm are verified. this research not only improves the efficiency of the mobile nursing system and provides solid technical support for practical applications, but also provides valuable theoretical foundation and practical experience for the further optimization and application of intelligent scheduling algorithms.

the worldwide shift toward electric vehicles (EVs) aims to mitigate climate change and reduce pollution. Advancements in battery technology have significantly boosted the EV industry, accelerating the transition from hybrid to fully electric vehicles. To sustain this growth, the widespread availability of EV charging stations (EVCS) is essential. However, integrating EVCS into the distribution network introduces challenges, including potential power system constraints and quality standards violations. this study proposes an optimal approach for integrating EVCS into distribution systems while adhering to power quality constraints, such as minimizing energy losses, enhancing voltage stability, and improving the system power factor. A Genetic Algorithm is employed to define the optimal locations for EVCS, Vehicle-to-grid (V2G) allocation, and V2G power factor. Simulations are conducted using the radial system ieee-33 bus, along with load curves and EV charging/discharging profiles, demonstrating the proposed approach's effectiveness in improving voltage stability and reducing energy losses.

this paper studies the application and key technologies of edge intelligence technology in long-distance, large-scale, and complex environment power inspection. Traditional power inspection relies on cloud computing, but when faced with real-time and low-latency requirements, the cloud computing model has limitations and is difficult to adapt to the inspection needs of complex environments. this study first analyzes the current status and technical challenges of power inspection, and proposes a solution based on edge intelligence. through a multi-layer architecture design, the collaborative work of data collection, real-time processing, and global analysis is realized between the perception layer, edge computing layer, and cloud layer. On this basis, the key technologies of multi-source data fusion, fault diagnosis algorithm, and system optimization are studied, especially for the specific application of long-distance transmission line and substation equipment inspection scenarios, and performance evaluation is carried out. the results show that the edge intelligence system has significant advantages in reducing data transmission delay, improving fault identification accuracy, and enhancing system responsiveness. this study shows that edge intelligence technology provides a more real-time, stable, and reliable solution for power inspection, and has broad application prospects.

Data-intensive grid applications need access to large datasets that may each be replicated on different resources. Minimizing the overhead of transferring these datasets to the resources where the applications are executed requires that appropriate computational and data resources be selected. In this paper, we introduce a heuristic for the selection of resources based on a solution to the Set Covering Problem (SCP). We then pair this mapping heuristic withthe well-known MinMin scheduling algorithm and conduct performance evaluation through extensive simulations.
