Abstract: Due to its intermittency and power fluctuations, the large-scale renewable energy resources, may cause negative impacts on power quality, security and stability, etc. when integrated into the power grid. An effective solution is thus provided by virtue of the energy storage technology for power systems with high penetration renewable energy resources. In this paper, after combing through the existing types and typical applications of energy storages, the basic models containing energy storage part and electricity conversion part are summarized, and the control strategies are given from single point control to multiple points coordination control. Then the application scenarios of energy storages in power systems are analyzed including power fluctuation stabilization, peak load shifting, transmission capacity improvement, power quality improvement, frequency modulation and system operation safety enhancement, and so on. In addition, the development trend of large-scale application of energy storage is explored in the aspects of the device development, planning optimization, operation control and business mode. Furthermore, the positive role of energy storages in energy internet is discussed.
