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.

Artificial intelligence technologies represented by machine learning and deep learning have been studied and applied in the field of power grid regulation, but there are problems such as scattered application results and poor data resource sharing. In order to meet the application requirements of artificial intelligence in power grid regulation and improve the training effect of the model, relying on the multi-level shared architecture and massive data resources provided by the regulation cloud, cloud edge collaboration technology is adopted to design the generation and sharing method of regulation business sample data, achieving collaborative management of sample data, and promoting the inheritance and development of resources and experience in the regulation field. © 2023 IEEE.

As the construction of the new power system progresses, the marked increase in the penetration rate of renewable energy, the intensified coupling of multi-energy systems, the closer interconnection among regional power grids, and the accelerated advancement of electricity market reforms have significantly heightened the complexity and uncertainty of the system. These developments pose substantial challenges to the existing dispatching technologies. In this paper, an auxiliary decision-making model through comprehensive utilization of multi-type active power adjustment resources is proposed. Firstly, the paper presents the framework of the auxiliary decision-making model. Then, the paper proceeds meticulously to establish the auxiliary decision-making model, including variables, the objective and constrains. Finally the validity of the model is verified using actual grid data from a specific region. © 2024 IEEE.

The current electric power system practices hierarchical and zonal administration to facilitate more effective monitoring of grid safety and event management. With an escalating integration of new energy sources on the generation side, the intrinsically variable nature of these resources introduces substantial uncertainties into grid operations. Meanwhile, on the demand side, load profiles are diversifying further, significantly influenced by weather conditions, market price signals, or incentive schemes, thereby adding another layer of unpredictability. Against this context, this paper proposes an intra-day rolling optimal strategy considering whole dispatch process and multi-type adjustable measures. By synthesizing regulating resources from both the source and load sides, it undertakes a series of intra-day rolling optimization decisions across the entire dispatch workflow. This strategy aims to harmonize and optimize the allocation of various resources, thereby ensuring the secure and stable functioning of the electrical grid amidst the complexities introduced by the integration of intermittent renewables and the dynamics of diversified loads. © 2024 IEEE.

Blockchain has the characteristics of smart contract, distributed decision-making, collaborative autonomy, tamper proof high security, openness and transparence. It is suitable for the power spot trading market in terms of operation mode, topology and security protection, and can well support the construction and protection of the power spot trading market. Firstly, this paper expounds the basic principle of blockchain technology. Then, the model architecture of power spot trading market supported by blockchain is studied, and the market transaction process covering the whole process of transaction announcement, transaction declaration, market matching, data deposit and certificate is designed. Finally, based on the application scenario of "multi buyer and multi seller" in the power market, a block chain based power spot market transaction simulation platform is built to realize the efficient distribution and rational utilization of energy, and the feasibility of the transaction mechanism and method is verified by simulation experiments. © 2022, Springer Nature Singapore Pte Ltd.

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.

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 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.
