Entering Yu Village, Anji County, Huzhou City, Zhejiang Province, the birthplace of the concept of "two mountains", the former mine pit became a cafe and the cement plant became a zero-carbon building. Sharing electric cars and electric sightseeing cars to shuttle freely; The whole village has achieved green electricity coverage, and homestays and farmhouses have received green electricity certificates one after another......

Here, the reporter saw a future village called "green.

In this "green" future village, the power company is exploring the construction of a magical microgrid. What does it look like? What kind of function does it have? We found the answer in the Future Village Green Power Service Center located on the east side of the Yucun Village Committee.

  Microgrid refers to a small power generation and distribution system composed of distributed power generation, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc., which can be connected to the external grid or operated in isolation. The application of microgrid can realize the flexible and efficient application of distributed power supply, solve the problem of large number and various forms of distributed power grid connection, and realize the high reliable supply of various energy forms to the load.

In the future rural green power service center, Li Qin, deputy director of the marketing department of Zhejiang Huzhou Anji power supply company, made a few super-light points on the tablet computer, and the lighting, screen, air conditioning and other facilities in the building were automatically turned on. Real-time monitoring data is beating on the big screen. This building, which integrates the five functions of power supply, power supply, power protection, green power and smart power, is operating in a "zero carbon" mode.

The real-time carbon emission management system that realizes the "zero carbon" operation of this building is called "Carbon Cube".

"Carbon Rubik's Cube is an energy control system, or an energy steward '." Li Qinchao said, "For example, if we have good light during the day, the' Carbon Rubik's Cube 'will control the energy storage and store the excess electricity from photovoltaic power generation. When it is cloudy or at night, the electricity will be released for the whole building to realize the operation effect of' zero carbon."

The green electricity service center has a variety of green electricity elements such as roof photovoltaic, intelligent switch station, ground source heat pump, mobile energy storage station, automobile charging pile, scenery storage intelligent street lamp, etc. The "carbon cube" can realize the coordinated operation of all elements, monitor and collect environmental information such as temperature and humidity, air quality and light intensity, accurately calculate the emission of buildings, dig deep into demand side response resources, and realize automatic control of energy-using equipment.

Not only that, but the "carbon cube" is also suitable for scenarios such as enterprise energy monitoring and commercial building energy hosting. As far as the main building of the green power service center is concerned, it can save more than 3000 degrees of electricity per year, reduce carbon dioxide emissions by more than 2.3 tons, and reduce electricity costs by 2500 yuan.

"This building integrates 'source, net, load, storage and charge, 'and covers all the representative elements of the future rural microgrid energy. It can be regarded as a miniature version of the countryside." Li Qinchao said, "In the future, we will vigorously promote the construction of solar power generation in public buildings in Anji, unite the microgrid deployment of 'energy storage' technology, and let the 'carbon cube 'participate in the construction of rural microgrids through upgrading and transformation."

As the country's first future rural green power service center, the exploration of microgrids here depicts the future supply and use of rural energy, and also provides a "green" sample for Yu Village to build an all-factor zero-carbon rural construction.
