With the continuous expansion of the scale of control cloud construction, the application of the platform has gradually increased, and the calling relationship between application containers has become increasingly complex. Ensuring the safety and stability of the control cloud platform has become a key factor in maintaining the normal operation of power dispatching. Therefore, it is urgent to carry out research on monitoring and management technology for lightweight container clusters to regulate cloud platforms. This paper designs the overall architecture of a lightweight container cluster monitoring and management platform with a hybrid structure from the host dimension, container dimension and application dimension. On the premise of ensuring data accuracy, it reduces the proportion of resources in the monitoring system and improves the scalability of monitoring indicators. At the same time, simulation experiments are carried out in terms of index collection performance and dynamic expansion of monitoring indicators. The verification results show that the monitoring scheme based on the hybrid architecture can flexibly and dynamically monitor the cloud platform in real time and ensure the safe and stable operation of the cloud platform. © 2022 IEEE.

With the continuous promotion of the construction of dispatching and control cloud, the existing service interaction mechanism has network security risks. At the same time, the service deployment is cumbersome, which affects the efficiency of service interaction. Based on the service proxy, cloud-side collaboration is used to complete the service interaction between two levels of clouds, which can improve the efficiency of the service deployment and interaction. On this basis, the overall architecture of the wide-area cloud-edge service collaboration and interaction of the dispatching and control cloud is completed. © 2022, Springer Nature Singapore Pte Ltd.

To improve the algorithm performance of mixed integer programming, determining the state of some integer variables in advance is the most direct and effective method. In this paper, we propose a heuristic algorithm based on characteristic analysis of unit and load for unit commitment problem. Starting with the initial state of a given unit, the state of every unit at each time point is examined. Then, the unit is considered to be put into operation when the system positive reserve not be met, and taking the load intersection line across this operation point to obtain all load characteristic values corresponding the unit, such as the load intersection point, intersection point-pair, regression time and so on. Finally, based on the division of load period, the treatment of the unit is determined one by one. By testing the standard examples and practical examples, the proposed method can save about 30% of computing time, which effectively improves the performance of mixed integer programming. © 2023 IEEE.

The era of big data is characterized by rapid information change, large volume of data, many dimensions, and various types, which requires enterprises to classify and grade data management. Especially in the critical period of new power system construction, a method is needed to classify and share power grid dispatching and operation data safely. This paper analyzes the business characteristics of power grid dispatching and control data, and designs the classification principle of power grid dispatching and control operation data, and builds a data sharing open directory based on this principle, and proposes a method of interaction and sharing of power grid dispatching and control operation data. Finally, this paper realizes the internal sharing and external circulation of power grid dispatching and control data through the interaction process. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

With the increasing complexity of dispatch automatic generation control (AGC) systems, evaluating the software complexity has become essential for optimizing performance and improving reliability. This paper investigates the complexity evaluation of AGC software by analyzing its operational and functional characteristics. A complexity evaluation model is constructed from the perspectives of code structure and software structure. The model introduces a structural complexity indicator based on functional network density and evaluates corresponding metrics using the grey relational analysis (GRA) comprehensive evaluation method. Case studies are conducted to verify the feasibility and applicability of the proposed method. The results demonstrate that this model and evaluation method can provide valuable support for improving software quality, optimizing software testing strategies, and guiding the development of more efficient AGC systems.
