The most electricity-consuming city is born!

Is there really a city with the highest electricity consumption?

Well, with the powerful support of the construction of ubiquitous power Internet of Things, such a city has really appeared.

So, how can you use electricity to create a flower?

Don't worry, look down -

Where are the electric cows used in this city?

The premise is that the power grid is very powerful. Without a very powerful power grid, there will be no such thing as very powerful electricity consumption.

100% consumption of renewable energy, safe installation of photovoltaic power generation

The photovoltaic power generation equipment installed in Mr. Gu's home can not only be used as needed, but there is no need to worry about the excess electricity being wasted. It can be automatically sold through the large power grid, bringing in a net profit of more than 100 yuan every month.

Not only Mr. Gu's home, there are also many distributed photovoltaic and wind power generation equipment in the area, with a total capacity of 580.189 megawatts and an annual power generation of 62.5 billion kWh. As we all know, renewable energy such as wind and light are unstable and difficult to absorb. However, the power grid here can effectively "control" these unstable power sources and achieve 100% absorption. Yes, it absorbs all of them.

Electricity bill diagnosis "customized" can save hundreds of dollars a year

Last year, Mr. Fang, a citizen, used the "Energy Usage Analysis" function of the "Power on Palm" app to find out, based on his household electricity usage habits, that if the peak and valley electricity prices were implemented, he would save a lot of electricity bills per year compared to the normal electricity prices. So Mr. Fang applied for a change in the electricity price calculation method online.

Sure enough, this summer, Mr. Fang and his family did not deliberately reduce the use of electrical appliances, but they paid several hundred yuan less in electricity bills than last year.

Smart electricity management, just move your finger, "no need to run once"

Mr. Sun is the head of a local textile and clothing company. Not long ago, he applied for a high-voltage capacity increase through the "Palm Power" APP on his mobile phone. The next morning, the customer manager of the power supply company came to inspect. Soon, the capacity increase plan came out, and civil engineering and electrical equipment construction also started one after another. The customer manager tracked the progress of the project online...

From applying for electricity to installing the meter and connecting the electricity, Mr. Sun never went to the power supply company once, and the matter was done.

When the sun comes out, charging becomes cheaper

There are many local people who use electric cars. On the evening of August 29, Jia Jia, who worked in an elevator factory in the suburbs, drove her electric car home after get off work. There is a DC charging station near the elevator factory, and Jia Jia goes there every time to charge her car.

The charging piles there are not ordinary, not only safe and reliable, but also often have discounts. How reliable and preferential? If there is a power outage due to a fault, the system will immediately automatically dispatch the reserve power to the charging pile, which can achieve seamless connection and zero flicker. The local photovoltaic power station is an important power source for the charging pile. The system can adjust the price according to the collected photovoltaic power generation information and notify customers to come and charge cheaply.

Buildings become smarter and save electricity

On August 29, data from the Municipal Public Institution Energy Conservation Monitoring Center showed that after the smart building transformation, the daily electricity consumption of the Municipal People's Hospital was reduced by 22% compared with the same period last year. Why can it save so much?

▲Smart switches that can automatically turn off lights and air conditioners. The "Please turn off the lights" reminder that was posted before has lost its effect.

Smart building renovation mainly involves installing or renovating lighting switches, air conditioning controllers, window insulation equipment, etc. in the building. Lights and air conditioners can be automatically turned on and off through human infrared sensing to avoid unnecessary waste. Currently, 58 unit buildings in the city have completed the renovation, and the average daily electricity consumption can be reduced by 20.2%.

There was a power outage at night, but we still had electricity! What’s the principle?

On the evening of August 9, due to the typhoon, some areas of the local area were without power. However, Li Feng, a "sports expert", still went to the gymnasium in the power outage area with his badminton racket on his back.

▲Inside the energy storage power station

No electricity, playing in the dark? Of course not, there are two 2,000 kWh energy storage power stations near the gymnasium. The pre-stored electricity in the energy storage station has been sent to the gymnasium through the microgrid, and the gymnasium is bright.

Which city is so powerful?

It's really amazing and advanced. I'm so envious! Don't keep us in suspense. Where is this? The answer is revealed——

On August 29, the comprehensive pilot demonstration project of urban energy internet in Jiaxing, Zhejiang Province passed the acceptance of Zhejiang Provincial Energy Bureau. This marks that the first urban energy internet demonstration project in the country has been completed in Zhejiang.

The core demonstration area of ​​the project covers Haining City, Jiaxing, achieving 100% access and consumption of renewable energy, realizing the extensive open interconnection of clean energy, efficient power grid, low-carbon buildings, smart energy use, and green transportation, and realizing green sharing between the power grid side and the consumer side.

That’s right, the city with the highest electricity consumption is Haining, Zhejiang.

Why is it so awesome?

Friends in Haining City can use electricity in such an advanced way thanks to this urban energy Internet demonstration project.

This project was jointly submitted by State Grid Zhejiang Electric Power Co., Ltd. and Jiaxing Haining Municipal People's Government in March 2017, and was successfully selected as one of the first batch of "Internet +" smart energy projects of the National Energy Administration. It is based on "strong smart grid" and "ubiquitous power Internet of Things" and relies on active distribution networks. It plans to build a comprehensive urban energy service platform, integrating and providing five major services including clean energy, building energy efficiency, supply and demand interaction, smart energy use and green transportation. It has successfully created a smart, open, shared, diverse and comprehensive urban energy Internet project model, and has become the pioneering practice of State Grid Zhejiang Electric Power in exploring the construction of a world-class energy Internet enterprise with "three types and two networks".

The city-level energy Internet demonstration project breaks the "information island", realizes the sharing and integration of all business data, integrates one-stop clean energy services such as new energy planning, construction, and operation, all-round Internet + building energy-saving services, "no need to run once" smart energy use services, and green transportation services of vehicle-pile-network interaction. It has opened up the comprehensive energy industry chain and provided unprecedented green and convenient electricity services to all types of customers.

I believe that with the continuous advancement of the construction of ubiquitous power Internet of Things, more cities will have their own energy Internet in the future. The future urban energy Internet will also be more scientific, efficient, practical, and even more awesome! Looking forward to it~
