摘要: The use of renewable energy and conservation of fossil fuels have become important strategies of the world to maintain sustainable development. Large-scale and high-efficiency energy storage technology is urgently needed to remove the random and intermittent nature of many renewable energy sources and to increase the compatibility of the renewable energy with the grid. The redox flow battery (RFB) as an electrochemical energy storage technology, with its advantages of long cycle life, high energy convention efficiency, flexible system design, deep-discharge capability and low cost, has been given much attention in the fields of renewable energy (such as solar and wind energy) integration and smart grid construction. After the successful development of hundreds of kilowatt class RFB, Dalian Rongke Power Co., Ltd. (RKP) combined with Dalian Institute of Chemical Physics (DICP) began on the research of technologies of larger battery module and mega-watt VRB system for wind farm use. A newly developed 22kW battery module is composed of 50 single cells. The charge and discharge performance of the module was examined by Arbin Instrument. The results show that the energy efficiency and the columbic efficiency of the 22kW battery module are 79.6% and 95.8% respectively at 80mA/cm2. A sub-system of 176kW VRB system was designed with eight 22kW battery modules in series, which will be a basic subsystem for megawatt system. The size of such 176kW/350kWh sub-system is 5,100×5,600×3,200 (mm). The DC/DC efficiency of the whole system is about 70% when it was charged / discharged at 80mA/cm2. A demonstration project of megawatt class VRB system applied in wind farm is undergoing. Aiming to pushing the industrialization and commercialization of RFB technology, RKP propel the VRB demonstration actively. Recently, a 60kW/600kWh VRB system was installed in an electric vehicle (EV) charging station. This VRB system can charge three EVs by storing the valley power. A joint PV-VRB system of 10kW/200kWh VRB and 20kW PV was installed on an isolated island. This off-grid PV-VRB system achieves the power supplying of the island.
