On the 17th, the 8th Yangtze River Delta Energy Forum was held in Shanghai. The reporter learned from the forum that during the “12th Five-Year Plan†period, Shanghai will focus on building a strong smart grid that is based on UHV transmission and has advanced international standards. It is estimated that by 2020, the electricity demand in Shanghai will decrease by 1.26 billion degrees.
According to the introduction of the deputy general manager of Shanghai Electric Power Co., Ltd., the so-called “Strong Smart Grid†is, in short, a strong UHV power grid as the backbone network rack, supported by a communications information platform, and modernized by means of intelligent control. Grid system. It can withstand disaster damage, prevent multiple failures, and make power supply more secure and reliable. New energy sources such as solar energy and wind energy can be connected to such power grids on a large scale, and they can enter enterprises and households through intelligent resource allocation to cope with the tight supply of thermal power.
In the framework of a strong smart grid, the energy storage base can store solar energy and wind energy centrally, and dispatch them in a unified manner. By “cutting peaks and filling valleysâ€, it shifts the load of a part of peak electricity consumption to the low-power phase of the night to save energy. Mitigation of grid pressure. "Intelligent buildings" matched with a strong smart grid can interact with the grid to achieve two-way interactions, making it possible for people to stay in the office and be able to view and manage the energy consumption of appliances at home and use electrical appliances more rationally.
It is precisely because the strong smart grid has these strengths. The future indicates that after the grid is built, the transmission efficiency and energy efficiency of Shanghai's power resources will be greatly improved. It is estimated that by 2020, the city's electricity demand can be reduced by 1.26 billion kWh, saving about 6 billion tons of standard coal and reducing carbon dioxide emissions by 1.6 million tons, making the metropolis of Shanghai greener and smarter. The future is also predicted that in the next 10 years, the construction of a strong smart grid will drive an annual output value of 10 billion yuan, and increase the number of 8,000 jobs per year, showing high economic benefits.
Today, Shanghai is fully advancing the construction of a strong smart grid. In more than a dozen pilot projects, Xiangjiaba-Shanghai UHVDC transmission project is an important part. Since it was completed and put into operation last year, this DC transmission line with the largest transmission capacity, the longest transmission distance and the highest voltage level in the world today has added 32 billion kWh of clean energy to Shanghai every year through hydroelectric power generation, accounting for the year of the city. 30% of electricity sales.
In order to make the “client†of the smart grid smart with automation capabilities, by the end of this year, the city plans to implement the transformation of 200,000 users' fiber-to-the-home power, and the newly-developed community of more than 80,000 square meters will fully promote the fiber-to-the-home deployment of households. The centralized meter reading, automatic power distribution, automatic measurement and recording of loads, and acquisition of electric energy, etc. in the form of power optical fibers.
