The hottest smart grid will be the future directio

Smart electricity will be the future direction of power development in Japan

it is reported that Japan is carrying out an empirical experiment of using a device called power router, also known as digital electricity or smart electricity, to flexibly dispatch the power generated in the region

in the early stage of the smart electricity revolution, Japan has been out of the picture. Because compared with other countries in North America, the country's electricity is much more reliable and strong. Relying on its successful nuclear power program, Japan has no huge demand for cutting power consumption peaks. However, the outbreak of the Fukushima nuclear disaster suddenly plunged Japan into a dilemma of alternating power outages and supply shortages. Therefore, TEPCO finally decided to deploy smart meters

view the comprehensive utilization of bulk industrial solid waste is expected to reach 1.4 billion tons in 2017. 1: clean energy in smart electricity will be the focus of Japan's future power development. The reform of the basic industry is to relax the access direction.

according to the recently released global new energy development report 2015, Japan's cumulative installed capacity of photovoltaic accounts for 17.4% of the world, ranking third only to Germany and China. It is understood that the Olympic Games has always pursued "faster, higher and stronger". When hosting the Olympic Games, all countries will focus on higher standards of energy technology and greener energy. Japan's embrace of renewable energy, especially solar energy, can not only prepare for the 2020 Summer Olympic Games, but also be the main direction of Japan's future energy security and national security. 4.

after winning the right to host the Olympic Games, Tokyo also launched a special plan for renewable energy development, set the goal of distributed photovoltaic power generation, and also implemented roof rental projects. Residential owners and commercial building developers can rent roofs to solar power developers and charge a certain rental fee

in addition to policy incentives, enterprises and commercial forces are also building Japan's Solar Empire. Like China, Japan is also a large photovoltaic manufacturing country, with many excellent photovoltaic manufacturing enterprises, including Kyocera, Mitsubishi, Sanyo, sharp and solar Frontier (a subsidiary of Showa shell oil). The parent companies of these enterprises are manufacturing giants or fossil fuel companies' transformation attempts

there is also a solar energy Museum in Japan. The museum is mainly for children, teenagers and other public to show the advantages of solar energy. This has a similar function to the clean energy exhibition center of domestic hanergy, which promotes solar energy through experience. In addition to the enlightenment and education markets, the Japanese government and businesses are also very actively developing distributed photovoltaic. Since there is not enough land, they should develop water and air projects. They install solar panels on the water and are still studying the cosmic photovoltaic power generation plan

viewpoint 2: digital electricity is a model of interconnection and power supply.

the concept of "digital grid" works by building multiple units including power generation equipment, power consumers and storage devices, and flexibly connecting these units by using digital electrical routers (DGRs) with IP addresses. DGR can digitize analog power and cut off the power connection between power generation equipment and power users, so as to liberate power generation equipment and power users from various power constraints. And through unified digitalization, the power system and control information system realize virtual integration, and also realize integration with the settlement system. In other words, intelligent electricity only digitalizes the information system of analog power, while digital electricity is to digitalize the power system, information system and settlement system

Mr. Abe Riya, a distinguished professor of technology business strategy in the Department of engineering, Graduate School, University of Tokyo, and a representative director of the general corporate digital electricity alliance, believes that the enterprise form of energy service provider (ESP) will become a necessary condition. The energy service provider is the "brain" of the unit. Several energy service providers conduct transactions in the electricity market, and then give instructions to operators according to the transaction results

renewable energy such as solar energy is being popularized. In this context, it is also necessary to build a mechanism to store surplus electricity in a "warehouse". As a power warehouse, the battery does not have to be large. Because electricity is transmitted at the speed of light, even if the warehouses are all over Japan, they can be used instantly. There is no need for large-scale battery technology. Electricity is only "information" and can be transmitted at the speed of light, so it is only necessary to build a mechanism that warehouses are spread all over the country and can be used instantly, and use information communication 3 Do not remove the two screws of the gauge rod to control it

as a country with an extreme shortage of energy, Japan has a small geographical area and mostly mountainous areas. Encouraging people to install individual solar energy and use the Internet to allocate power storage and transmission is the best option for Japan to develop clean energy and change the current energy use pattern. It can not only greatly reduce risks in energy security, but also improve the environment and form a new energy business model, which can be described as killing many birds with one stone
