Review of Basic Theory and Methods of Morphological Evolution and Safe&Efficient Operation of New Distribution System
The distribution network is an important support point for energy transformation.The distribution network driven by the"carbon emissions peak and carbon neutrality"goal will undergo major changes,and it has rapidly changed from a passive distribution network to a resource allocation platform that actively balances regional power supply and demand and supports comprehensive energy utilization,showing a stronger feature of systematic,that is,from distribution network to distribution system.We first summarized the relevant research from three dimensions,namely,morphological evolution path,multi-dimensional coupling relationship,and core research methods,and preliminarily put forward the fu-ture evolution law and evolution direction of the new distribution system.Then,we summarized and discussed the key technologies involved in the evolution process of the new distribution system,namely,fault protection and self-healing technology,oscillation analysis and suppression technology,system stability control technology and collaborative sched-uling technology.Furthermore,by analyzing the application of key technologies in typical cases,the gap between the current technical status and future needs is clarified.Finally,the future development direction of the new distribution sys-tem related technology is presented.
