Resilience of power system with integrated energy in context of low-carbon energy transition: review and prospects

At present, power system is transforming into a clean and low-carbon power system with integrated energy. The output power of renewable energy is intermittent and stochastic, which has an adverse effect on the power system with integrated energy. Besides, the large disturbance in single energy subsystem caused by extreme events may create cascading failure in the whole power system with integrated energy. In order to enhance the ability of power system with integrated energy to withstand and cope with extreme events, the related research for resilience evaluation and improvement is becoming more and more important. Firstly, the concept of the resilience of power system with integrated energy is introduced. Then the resilience evaluation index and operation state analysis method are analyzed and summarized. In addition, the resilience promotion measures are studied and prospected from the perspective of multi technology integration. Finally, the problems and challenges of related research are described and analyzed.
