Core value of the smart grid is to improve energy efficiency and reduce greenhouse gas emissions, using a variety of high-tech means to enhance the generation, transmission , distribution , operation and management level of all sectors of electricity , saving resources and protecting the environment.

   In recent years, some European and American countries to advocate for and actively develop smart grid , which was elevated to the country's energy , highly sustainable environment and economic development strategies to fully implement , and recent attempts to achieve the effect of stimulating the economy by investing in the development of smart grid construction . In the international financial crisis, Obama's economic stimulus plan includes accelerating the development of the smart grid .

    Smart grid can improve energy efficiency and protect the environment . Core value of the smart grid is to improve energy efficiency and reduce greenhouse gas emissions, using a variety of high-tech means to enhance the generation, transmission , distribution , operation and management level of all sectors of electricity , saving resources and protecting the environment. Promotion of smart grid can be reduced by more than 25 percent of the carbon dioxide produced by power generation , which is equivalent to 130 million car starts instantly emissions of carbon dioxide . Smart grids can also enhance supply and service quality, and promote the development of the whole industry chain.    In short, the smart grid will be emphasized in the existing power grid is safe, reliable , stable, and taken to a new level , further demonstrates the power of positive contribution to the environment , economy and society as a whole .

   Smart grid technology to improve the electricity distribution network and management level

   Speaking of the distribution network of intelligence, a lot of people will think of distribution automation . Distribution Automation of course an important part of smart distribution grid, but it just implements to improve power supply reliability, shorten outage time and some other functions. The intelligent distribution network is an organic integration of multiple information and functional modules . The so-called organic integration, namely through the data / information management across platforms to achieve more and more advanced applications . It is a greater emphasis on enhancing the level of the entire distribution network operators , such as: how to load shifting through the effective transfer of load distribution more power on the basis of the existing grid , rather than simply increasing investment in infrastructure ; how the whole network without power / voltage management , reduce line losses ; how real-time load forecasting and meteorology, linking distributed energy , combined with TOU guide customers to the consumer , increasing the average hours of full utilization of existing generating units , rather than simply adding new units to meet peak demand unplanned ; how to improve the grid 's own crisis management capacity , so that with the failure of early warning , rapid judgment, self-healing and other " self-healing " function. Smart distribution network but also through advanced simulation grid quickly , many visualization tools, intelligent expert system to help improve the efficiency of production scheduling personnel.

    Many regard the U.S. power company smart meter installation and construction of an advanced metering system as an important part of building a smart grid. As electricity customers with real-time interactive tool for power companies , smart meter has two main functions: First, it is to achieve information and control terminal demand response ; Second, it is a power outage management, power quality management and other functional modules sources of information, it will be with the entire camp system fault location and power supply monitoring deep into the end . Plus integrated geographic information systems and expert systems , power companies can be more intuitive.
