Many countries actively carry out their own smart grid development plans

There is no doubt that smart grid has greater advantages than traditional grid, especially in resource allocation and accident response capabilities, many countries have announced their own smart grid development plans.
Smart grid will be the development focus of power network construction in some countries in the future. Japan plans to fully popularize smart grid by 2030, and at the same time, the government and the people will make every effort to promote the construction of smart grid overseas. In the field of battery, the global market share of Japanese enterprises aims to reach 50% and obtain a market of about 10 trillion yen. Japan's Ministry of economy and industry has established the "International Standardization Research Institute on the next generation energy system", and Japan and the United States have established the project of smart grid joint experiment in Okinawa and Hawaii.
The United States' smart grid, also known as the Unified Smart Grid, refers to the combination of distributed smart grid into a national network system. This system mainly includes: realizing the intellectualization of American power grid through unified smart grid, solving the needs of distributed energy system, connecting customers' power with long-distance, short-distance, high-voltage and low-voltage smart network; constructing new transmission network on the premise of protecting environment and ecosystem, realizing the optimized transmission and distribution of renewable energy, improving the reliability and cleanness of power grid; this system It can balance the demand of cross state power consumption and realize the optimal power dispatching, monitoring and control nationwide, so as to realize the overall power demand management in the United States and realize the balance of renewable energy supply across regions in the United States. The other core of this system is to solve the storage of solar energy, hydrogen energy, hydropower energy and vehicle electric energy. It can help users sell surplus electric power, including solving the problem that the battery system resells rich electric energy to the grid. In fact, this system is based on the renewable energy in the United States to achieve the optimal management of the power generation, transmission, distribution and consumption system in the United States.
Recently, the Southern California Edison Company (SCE) announced that it plans to deploy a demonstration project on June 30, 2013, including: distribution infrastructure, substation, residential users, network security system, battery energy storage system and the construction of electric vehicle charging station in the University of California, Irvine. Ge is also a participant in the project.
The project can show the importance of public utilities, system integrators, regulators and customers to energy initiatives, including energy consumption load transfer, renewable energy grid connection, and energy storage solutions to determine cost-effectiveness.
Previously, the U.S. government focused on the construction of smart grid, focused on core technology research and development, and began to formulate development plans. In order to attract all forces to jointly promote the construction of smart grid, the US government has actively formulated the 2010-2014 smart grid Research and Development cross annual project plan, aiming to comprehensively set up smart grid Research and Development projects, so as to further promote the development and application of technology in this field.
