弹性电网关键技术研究的进展与展望OACSTPCD

The development of modern power grids is becoming more and more complex,and new power supply threats are increasing.Especially in the development trend of a large number of new energy systems connected to the grid,the tradi-tional power system will appear extremely vulnerable when encountering sudden shocks or disturbances,which undoubted-ly cannot satisfy the increasingly strict power quality requirements of users or power companies.In order to maintain the basic operating functions of the power grid in the event of small probability and high loss,the"resilient power grid"with resilience,adaptability and rapid recovery capabilities has been favored by many scholars,which can effectively improve the elastic recovery of the system,strengthen the ability of system to resist disasters and disturbances,thereby improving the overall operational capabilities of the system.This paper focuses on the optimization strategy of resilient power grids.Firstly,it explains the basic architecture of resilient power grids based on the theory of resilient resilience.Secondly,it analyzes the key technologies used in the development of resilient power grids based on the method of improving system re-silience.The development trend of resilient power grid is prospected during the evolution from traditional power grids to future power grids.
