More than 20,000 poor households earned income from the priority use of clean energy in Fujian's smart grid

The cheap electricity stored at night can be “moved” on a large scale to work during the day, the photovoltaic power generation of poor households sells all the money, and the charging station covers the whole province... Fujian Province passes the “smart grid”, all of which consume clean energy and reduce the use of enterprises. The cost of electricity has turned from a small “energy reserve” to a “clean energy province”.

On the large screen of the dispatching hall of the State Grid Fujian Electric Power Co., Ltd., the staff used the mouse to see the operation of the reservoir hydropower station, photovoltaic power station, wind farm and charging station throughout the province at a glance. According to reports, according to these data, grid dispatchers scientifically arrange the power generation of hydropower stations, and conduct real-time monitoring of wind power and photovoltaic power plants across the province, and perform multi-energy complementary optimization scheduling to maximize the power generation capacity of clean energy and achieve intelligence for many years. Dispatching and water energy and wind power utilization ranked first in the country.

Wind power, photovoltaics, and hydropower are sometimes sent out more and sometimes less. It is called "eat by the sky". If the dispatch is not good, it will cause the phenomenon of "dwelling electricity", which will cause the excess power to be delivered in time. This intermittent and Volatility brings huge peaking pressure to grid operations. Fujian Province has abundant clean energy resources, all of which are safely transported through the “smart grid”. According to statistics, since 2000, the total electricity consumption in Fujian has increased by 423%. As of April 13, Fujian Power Grid has been operating safely and stably for 8375 days, and the length of urban and rural power outages has decreased by 67.09% and 58.83%, respectively. Wind, light and water. Gas, nuclear and other clean energy energy sales of 100%, the province every 1 degree of electricity has 1 degree from clean energy power generation.

Fujian is a national ecological civilization pilot zone. Through the implementation of electricity to replace coal, electricity to replace oil, and continuously improve the proportion of clean energy in the terminal energy consumption. At present, the province has built 608 charging and replacement stations, 13,500 charging piles, covering all highway service areas in the province, and 36,000 electric vehicles have been put into operation. “Smart Grid” conducts real-time monitoring and management of access facilities to ensure that electric vehicles are electrically rechargeable at any time.

Enterprises use the "smart grid" scheduling, which also exerts huge economic benefits. Fujian Guancheng Ruiqi built a storage power station and put it into operation according to the “Smart Grid” service. According to Wang Haoran, executive vice president of the company, the energy storage facility was charged during the nighttime preferential electricity price period, and the energy storage was sufficient for the next day, the office and staff quarters totaled more than 300 people to supply electricity, effectively reducing the cost of electricity and becoming a smart grid. One of the beneficiary companies.

It is worth mentioning that after the “Smart Grid” power information collection system is embedded in the distributed PV cloud network, it can provide full-service online services such as reporting, metering and settlement for photovoltaic power generation, effectively cooperating with local implementation of precise poverty alleviation. At present, State Grid Fujian Power has accepted 2,945 PV poverty alleviation projects, including 2812 grid-connected power generation projects, with a cumulative power generation of 61.33 million kWh. More than 20,000 poor households benefit from the province.

The digital technology of the power trading platform is also an important part of the "smart grid." According to reports, in order to promote clean energy trading, the power supply department has set up an information transaction and settlement platform between clean energy power plants and major customers through the digital technology of the power trading platform, which has effectively promoted the participation of clean energy in market transactions and nuclear power. Achieve optimal configuration and efficient consumption of clean energy over a wider range. In 2017, through the power trading platform, Fujian marketed electricity consumption of 38 billion kWh, of which clean energy accounted for 23.3%; provincial power transmission 6.8 billion kWh, an increase of 133%, including nuclear power of 3.3 billion kWh Year-on-year growth of 411%.
