With the rapid development of renewable energy power generation technology,new energy represented by wind and light has penetrated into the distribution network on a large scale.At the same time,technologies such as energy storage and active load are also widely used in distribution networks.The distribution network has evolved from a traditional power distribution network to an active distribution network with a complex shape and a flexible structure.Its operation and control are facing new problems and challenges.With the increase of a variety of physical equipment elements,the degree of intelligence in the construction of active distribution networks is gradually increasing,and the measurement and communication technologies are becoming more and more complete.The amount of data generated and observable by the entire network shows an explosive growth trend,Centralized data processing is difficult to adapt to and meet the needs of the active distribution network.In order to fully explore the value and potential of massive data and improve the ability of data processing and utilization,the theory and mode of regulation and control of active distribution networks must be distributed.In order to give full play to and reflect the active capability of the active distribution network,in the context of the era of big data and the Internet,it is of great significance and value to study and construct a distributed coordinated control platform for the active distribution network.After summarizing and analyzing relevant research at home and abroad,this paper takes the multi-agent system as the basic structure,and conducts detailed exploration and research on the distributed optimal scheduling of the active distribution network and the construction and application of related distributed platforms.The specific work results are as follows:(1)Based on the need for distributed coordination control of the active distribution network,the software form of using a multi-agent system to construct the active distribution network distributed platform is clearly defined,and the active distribution network is analyzed and elaborated based on the distributed software platform Hierarchical distributed structure framework and hardware foundation and communication network structure required for adaptation.(2)This article describes and analyzes the functions and characteristics of the multi-agent development platform JADE,and describes the deployment and development of the JADE platform as a core software tool for multi-agent system construction and the development of distributed coordination for active distribution networks.Control platform design ideas,and then use other software to build platform functional components.The foundation of platform construction is analyzed from three aspects:software structure design,software deployment and program development.(3)Proposed a two-layer coordinated coordinated operation scheme suitable for the distributed offline optimization and distributed online optimization of the active distribution network,and these two functions are used as advanced applications to illustrate their deployment on the distributed platform of the active distribution network With realization.Finally,the actual distribution network of a certain place is used as an example system,and the effectiveness of the advanced application integration operation of the active distribution network distributed coordination platform constructed in this paper is verified through the actual operation interface.
