Resilience Enhancement of Power Grid Considering Optimal Operation of Regional Integrated Energy System Under Typhoon Disaster

摘要

In extreme weather, serious large-scale blackouts will occur in the power grid. Resilience reflects the ability of the power network to resist extreme disasters, reduce losses in fault and restore power supply as soon as possible. Boosting the resilience of power system is one of the core requirements of smart power grid. This paper proposes a coordinated optimization of regional integrated energy system (RIES) for enhancing resilience of power grid under typhoon disaster. The RIES with multiple energy equipment and demand response load is constructed, and the internal energy conversion relationship and optimal operation model of RIES are analyzed. Finally, the simulation results show that the grid resilience can be improved by considering the coordinated operation of RIES under typhoon weather.
