Collaborative task allocation method for protection and control intelligent terminal in distribution networks considering elastic allocation of resources

Abstract

With the development of new power systems, the protection and control tasks of distribution networks have become increasingly complex. When intelligent terminals are employed to handle these tasks, the requirements for balancing resource supply and demand have become move stringent. Therefore, a collaborative task allocation method for protection and control intelligent terminals (PCIT) in distribution networks considering elastic allocation of resources is proposed in this paper. Firstly, the technical architecture of multi-terminal collaboration is elaborated, and the container-based elastic resource model and task processing model within the terminal are established. Secondly, a two-layer model is proposed to optimize the cooperative assignment of protection control tasks among terminals and the elastic scheduling of resources. The implicit enumeration method is used to solve the model, so as to give full play to the flexibility of resources and improve the performance of task processing. Finally, the arithmetic example verifies the feasibility and advancement of the proposed method. The occupancy rate of computing resources of each intelligent terminal is reduced by about 28.85%, and the average processing delay of tasks is reduced by about 4.12%.
