The large-scale smog epidemic has exposed the environmental problems that have driven rapid economic growth for many years. Highly polluting industries have been forced to accelerate structural adjustments, while industries such as smart grids have ushered in new developments. opportunities. . The “China Smart Grid Industry Market Forecast and Investment Strategy Planning Analysis Report” released by Qianzhan Industrial Research Institute shows that There are four main factors driving the development of smart grids:
Factor 1: Various functions
Traditional power grids are difficult to meet the various needs of users, while smart grids can support distributed power generation with two-way power and communicationfunctional, and can interact with users. Users can choose to sell electricity based on the quality and price of electricity.
Factor 2: Stability
Compared to traditional power grids, smart grids are more stable, easy to maintain and convenient to supervise. According to statistics, losses caused by electrical interference in traditional power grids reach hundreds of billions of dollars every year. Power grid outages have a greater impact and smart grids can effectively avoid these problems.
Factor three: low losses
Currently, electricity transmission and distribution losses are basically more than 5%. Taking Japan as an example, the annual electricity transmission loss is $17.7 billion, Qianzhan. com Research reports on smart networksents estimate annual nationwide transmission losses in the hundreds of billions of dollars. The huge losses of traditional electricity networks no longer meet the requirements of energy saving and emission reduction, and the development of smart networks is urgent.
Factor 4: Intermittent power supply
As the proportion of wind and photovoltaic power generation in total electricity generation continues to increase, by 2020, wind and photovoltaic power generation in the United States, Japan, the European Union and other regions The proportion of electricity generation will exceed 10%, and a large number of intermittent power sources will be connected , and the traditional electricity grid will face serious challenges.
The Chinese province with the largest electricity generation capacity - Tibet
The largest photovo solar power plantTibet Taica, a 100 megawatt grid-connected large-scale photovoltaic power plant, has officially begun construction. In the 60 years since the peaceful liberation, the cumulative installation of high-grid photovoltaic power in Tibet has reached 9 MW, accounting for about 13% of the installed solar photovoltaic power generation capacity in China, and will become the province with the largest solar energy production. capacity in China.
Tibet is the Chinese province with the richest solar energy resources. Most regions enjoy more than 2,000 hours of sunlight per year, and annual radiation can reach 6,000 to 8,000 megajoules per square meter.
