Study On The Dispatching System Construction Of Cloud-based Computing Smart Grid

With the rapid development of smart grid,the application of dispatching automation system has gradually developed from basic dispatching business to information business applications such as data fusion,heterogeneous system interaction and big data analysis.However,the current mainstream dispatching automation system is difficult to adapt to big data analysis and other information business applications.On the basis of the existing hardware equipment of power grid dispatching automation system,the system processor resources and data resources can be integrated by cloud computing.It can greatly improve the analysis ability and real-time control ability of power grid and provide technical support for the development of intelligent dispatching system.Therefore,this paper is aimed to build an integrated dispatching system of smart grid based on cloud computing.Firstly,the current situation and problems of traditional power grid dispatching system has been analyzed.In order to form the software system architecture of intelligent power grid,the demand of cloud computing for smart grid dispatching system is pointed out,and the overall design is proposed.It involves the design of technical architecture,functional architecture,storage architecture and security.Secondly,a smart grid scheduling model based on cloud computing has been established.The objective function is to minimize the sum of the generation cost,network cost,operating cost of smart grid and the penalty cost conditional risk value.A scheduling strategy of the smart grid based on cloud computing is proposed,and a solution method is provided for the optimization problem based on penalty cost and conditional risk value model.Then,from the perspectives of business requirements,system design and cloud computing deployment of smart grid dispatching system,a cloud computing system of the smart grid,which based on the business requirements of power system dispatching automation,is constructed.In the process of building the integrated application of dispatching system,in order to improve the operating efficiency of the system,the design method,application integration and performance optimization method of the smart grid cloud computing system are proposed.It mainly includes the deployment cluster selection scheme and deployment method of the smart grid cloud platform,the performance optimization scheme of the cloud computing system,and the application scenario of cloud computing in the smart grid dispatching system.Finally,an example is built to verify the scheduling model.The results show that the scheduling system of smart grid based on cloud computing has good performance,can effectively improve the level of smart grid business application,and complete the corresponding scheduling.
