Abstract
ObjectivesTo address the impact of extreme high-temperature weather on the supply and demand balance of power systems, a medium- to long-term method for enhancing power system resilience is proposed.MethodsFirst, the coupled “source-load” output characteristics under sustained extreme high-temperature scenarios are simulated, and an initial evaluation of system resilience is performed using a chronological operation simulation model. Second, based on the operation simulation results, a resilience enhancement-oriented power resource planning model is established, with the objective of minimizing the combined cost of power supply and load shedding under the constraint of supply and demand balance, thereby deriving combined measures for resilience enhancement. Finally, operation simulations of the resilience enhancement strategy scenarios are conducted to verify their effectiveness.ResultsTaking Guangdong Province in 2025 as a case study, compared with the scenario without the implementation of the resilience enhancement strategies for power systems, the application of such strategies under extreme high-temperature weather decreases the cumulative power shortage, maximum lost load scale, and economic losses caused by power shortage by 86.71%, 60.72%, and 91.55%, respectively. The system’s minimum power supply level increases by 11.07%.ConclusionsBy coordinating the expansion of power supply resources and deployment of load resources, the resilience enhancement strategies effectively improve the power system’s supply capacity under extreme high-temperature weather, while reducing the economic loss and social cost caused by power shortages
