One can improve the efficiency of solar photovoltaic power plant using the “flow battery energy storage system integration and application of solar power generation demonstration” project, through the establishment of pilot demonstration in Lhasa point of testing, has recently completed the technical design and feasibility studies as well as the load line connection, etc., the project is expected to plateau this year in the city of solar PV power plant application.
Energy Demonstration Center, Office of the Tibet Autonomous Region, Li Jinxiang, director of presentations, solar photovoltaic power station in Tibet was build by using the battery, its lifetime is only three years, while the use of flow energy storage battery systems could take more than 15 years. Application in solar power, not only can reduce the use of cost, but also build the battery to reduce frequent replacement caused by environmental pollution. At the same time, but also solve the solar power, wind power exists in the electricity supply has fluctuated, the voltage instability problems.
This reporter learned that flow battery energy storage system is composed of a battery and a cathode storage tank, an anode composition storage tank. The principle is through positive and negative electrolyte solution in the activity of valence changes of vanadium ions to achieve electrical energy storage and release. The image that is deposited in the excess of electric jar, to use when the transmission went out again in order to ensure the stability and continuity of supply when.
At present, various types of solar photovoltaic power generation facilities in Tibet a total capacity of more than 9MW, Tibet is China’s highest rate of solar energy application, the application surface and the largest and most versatile of the provinces and autonomous regions, solar resources are widely used in agricultural and pastoral areas lighting, radio and television , boil water for cooking and heating in areas such as well received by the masses of farmers and herdsmen.
