Discussion on application experience of cloud computing in power industry

The application features of the power industry are very much in line with the service model and technology model of cloud computing. Cloud computing is the original dispersed resources gathered, and then to serve the form of the audience to achieve the group operation, intensive development, lean management, standardization of construction. The use of cloud computing, not only can realize the power industry data collection and sharing, and finally realize data mining, provide business intelligence BI, assist decision-making analysis, promote the coordinated development of production business, can also help grid companies to transform data into services, enhance service value, realize information neural network fusion. The research and application status of smart Grid cloud computing at home and abroad are as follows:

The application and development of foreign smart grid cloud computing

United States: In January 2009, Obama unveiled the Recovery Plan Scale report, announcing the laying or updating of 3000-mile transmission lines and the installation of smart meters for 40 million American homes, marking the US's move to the smart grid as a national strategy. America's top IT companies, IBM, Intel, Microsoft, Google, Apple and the upstart Salesforce.com, are all tapping into the smart grid market with their own advantage. It can be said that cloud computing in the United States Grid enterprise application development will become the global grid industry vane.

Europe: In the 2006, the EU Council's energy Green Book, "Europe's sustainable, competitive and safe energy strategy," clearly emphasizes that smart grid technology is a key technology and development direction to ensure the power quality of EU power grids. In Europe, the power development model to the distributed generation, interactive power supply and so on, the application of smart grid more emphasis on environmental protection and renewable energy generation Development, which is leading the development of the international grid another trend. At present, US it giants Microsoft, IBM, Amazon and so on in the European grid cloud computing market, but hindered by the EU's not uniform rules and psychological understanding.

Japan: The focus area of Japan's smart grid is the new energy sector. At present, Japan's distribution network has been very advanced, but with the increase of new energy supply such as solar power generation, it is necessary to introduce smart grid cloud technology to ensure the stability and reliability of power supply system. Japan's smart grid also advocates the concept of "Energy information", in addition to focusing on large-scale transmission network intelligence, pay more attention to the efficiency of household and community power consumption problem. Japan attaches importance to the development of household appliances "visualization" control system and power information Transmission control platform for electric power and energy consumption. Therefore, the development of cloud computing in Japan's smart grid will have Japanese characteristics.

Second, the domestic smart Grid cloud computing application and development

2009, the State Grid company for the first time proposed the development goal of Smart grid: the construction of UHV power grid as the backbone of the grid, the various poles grid coordinated development, with information, automation, interactive characteristics of the unified strong smart grid. National Network, the South network are actively involved in the development of smart grid standards. 2010, the Smart grid became the national strategy.

In theory, the intelligent power grid has formed the Tsinghua School of the optimal dispatching of power system, Professor Wu Jiandong has put forward the new theory of "interactive power grid", the two power grid companies actively carry out relevant research work respectively. In practice, the two power grid companies scramble to layout cloud computing strategy, the data center based on virtualization technology for resource integration, at the same time to build an integrated technology platform based on SOA architecture.

The national power grid is built into the intelligent grid Cloud simulation laboratory. The lab's mission is to build a smart Grid cloud computing Center, focus on the smart grid cloud operating platform, Smart grid cloud distributed database, Smart Grid Cloud resource virtualization management platform and based on smart Grid cloud operating platform of the ten typical applications, including cloud resource leasing system, Smart grid cloud Search, Smart grid cloud encyclopedia, Cloud Digital Library, cloud patent retrieval system, international cooperation business cloud application system, intelligent power consumption mass information storage and analysis, power video cloud and so on.

The Southern power grid has long attached great importance to the research and application of new technology. Taking Guangdong power grid as an example, since 2008, a series of technical standards and specifications, including the Public Information Model (ECIM), Data Resource planning, SOA Technical specification, Information security Protection Technical Specification, etc., have been carried out in order to create the first as the carrier and around the core goal of the level of scientific development. " Research on intelligent Grid information support technology, "Research on information technology system of Smart grid", "Comprehensive research on smart grid and information technology" and "advanced application of cloud computing in power industry". These are all important parts of the research work of smart grid and cloud computing technology.

View

As a new computing model, cloud computing has the advantages of high reliability, large data processing, flexible scalability and high equipment utilization, especially for the information technology requirements of smart grid construction. Therefore, the introduction of cloud computing in the field of smart grid technology can integrate the data resources and processor resources of the current system under the condition of guaranteeing the basic hardware infrastructure of the existing power system, so as to greatly improve the ability of real-time control and advanced analysis of power grid, and provide effective support for the development of smart grid technology.

The combination of cloud computing and power industry not only avoids the public insecurity of cloud technology, but also suits the construction of large power grid enterprises such as power grids. It is a need and a trend to introduce cloud computing into power system and build power cloud on the basis of existing power intranet.
