The large-scale concentrated smog outbreak can be described as exposing the environmental problems behind the sustained high-speed economic growth for many years, forcing heavily polluting industries to accelerate structural adjustment, while smart grid and other industries are welcoming new development opportunities. China Smart Grid Industry Market Foresight and Investment Strategic Planning Analysis Report Foresight released by Foresight Industry Research Institute shows that there are four main factors driving the development of smart grid:
Factor 1: Multifunctional
Traditional power grid is difficult to meet the diverse needs of users, while smart grid can support distributed power generation with two-way feed and two-way communication, and can interact with users, and users can choose power selling enterprises according to power quality and price.
factor 2: stability
compared with the traditional power grid, the smart grid is more stable, easy to maintain and convenient to supervise. According to statistics, the losses caused by power interference in traditional power grids reach hundreds of billions of dollars every year, and power grid failures have a great impact and slow recovery, while smart grids can effectively avoid these problems.
factor 3: low loss
at present, the loss of transmission and distribution is basically above 5%. Take Japan as an example, the annual loss of transmission is 17.7 billion dollars. The smart grid research report of Foresight Network estimates that the annual loss of transmission in China is hundreds of billions of dollars. The huge loss of traditional power grid no longer meets the requirements of energy saving and emission reduction, and the development of smart grid is imminent.
factor 4: intermittent power supply
with the increasing proportion of wind power and photovoltaic power generation in the total power generation, by 22, the proportion of wind power and photovoltaic power generation in the United States, Japan and the European Union will exceed 1%, and a large number of intermittent power sources will be connected, and the traditional power grid will face severe challenges.
