The port is a big consumer of electricity. With the expansion of the port scale, its consumption of electricity has been paid more and more attention. The main electrical load of the port is concentrated in the equipment with high power and long working time. Jiangsu Lianyungang plans to build a 5MW(1MW supercapacitor +4MW lithium) energy storage station in the port power system to meet the onshore power access demand of more than 10MW in total and 3MW in a single berth. When the onshore power runs at full load, there is enough margin to meet the access demand of a variety of random power supplies and loads.
At present, in some remote mountainous areas, islands and other places far away from the city, there are still some unenergized or unstable power supply "power blank area". On May 27, 2018, China's first far-sea island smart microgrid was completed in Yongxing Island, Sansha, through diesel power generation, photovoltaic, energy storage and other complementary energy, the power supply capacity of Yongxing Island increased by 8 times, and also realized the priority use of 100% of clean energy such as photovoltaic. In the future, flexible access to a variety of energy sources such as wave energy and mobile power can also be realized.
On December 31, 2018, the first phase of the 750 kW /1.8 MWH energy storage project of Fujian Magaai Memorial Hospital, constructed by Shanghai Power Construction Fujian Company, was successfully put into operation. This project is the first hospital system energy storage project in Fujian Province, which can realize the peak cutting and valley filling of the power grid when the power grid is normal, and can quickly disconnect the power grid in the case of power failure, so as to ensure the power supply of important loads in the hospital and fast access, and act as a UPS(uninterruptible power supply) to ensure the continuous power supply of important loads in the hospital. Provide solid power guarantee for the smooth operation of the hospital.
Nandu Power's Beijing Blue Jinglijia user-side commercial complex intelligent energy storage power station is located in the North Third Ring Road, Haidian District, Beijing, with a total project scale of 1MW/5MWh, of which the first phase of operation scale of 500KW/2.5MWh, the project covers a total area of 170 square meters. The energy storage system is connected to the bus bar of the distribution room of the shopping mall on the low voltage side of 400V, and the expected service life of the power station is 10 years. On May 22, 2017, the energy storage power station realized the capacity and electricity charge management of the home shopping mall and the management of electricity charges, solved the pain points of the home shopping mall line unable to expand and transform, and the impact of the electric vehicle charging access, realized the intelligent energy storage service of peak cutting and valley filling, and also participated in the power demand side response. In addition, according to the North Star energy storage network, Beijing Changping Dole Port is also planning to build energy storage facilities to cut peak and fill valley to save electricity costs.
In a garrison plateau camp in Xinjiang, the army's first military-civilian integration renewable energy LAN project invested by the New energy Company of Power Construction Group was launched in August 2018 and officially connected to the grid on December 26, 2018.
