Design and implementation of rapid restoration after large area blackouts on distribution network

Emergency Power Supply Restoration Strategy for Distribution Network Considering Support of Microgrids with High-Dimensional Dynamic Correlations

“…For the distribution system, with the rapid development of new energy technologies [2], distributed generation (DG) such as wind power and photovoltaic power generation is increasingly connected to the distribution network, which makes the structure of the distribution network larger and the power flow more complex, presenting huge challenges to the troubleshooting of the distribution network [3]. The traditional passive waiting time for fault elimination is up to dozens of hours, the use of fault reconstruction technology can significantly shorten the outage time [4], making the rapid repair technology of the distribution network more and more important [5,6]. The distribution network response to extreme faults is a multi-stage decision process, including fault diagnosis and isolation, islanding operation, and maintenance and restoration.…”

Research on load transfer strategy optimisation with considering the operation of distributed generations and secondary dispatch

“…With the acceleration of the urbanisation in China and the increasing scale of the distribution systems, the prevention of the large‐scale outage has become a crucial issue to the reliable operation of the power grid [1–3]. In recent years, the occurrences of the substation‐complete‐shutdown accidents (SCSA), caused by faults like the trips of double‐circuit lines on the same tower and feeder, have been reported frequently [4, 5].…”
