考虑先进绝热压缩空气储能的配电网韧性提升策略OA

To address the insufficient resilience of distribution networks under high penetration of renewable energy,this paper proposes a resilience enhancement strategy incorporating advanced adiabatic compressed air energy storage(AA-CAES).A dispatch model is formulated in which AA-CAES participates in grid contingency response,and the uncertainty of renewable generation is characterized using distributionally robust chance constraints based on the Wasserstein distance.Simulation tests are conducted on a modified IEEE 33-node system to validate the effectiveness of the proposed strategy.Results show that,with AA-CAES deployed,the loss-of-load rate during extreme events is significantly reduced-decreasing by 3.84%compared to the scenario without AA-CAES,at the cost of only a 1.17%increase in dispatch cost.The study concludes that the proposed strategy effectively enhances the power supply capability of distribution networks under disaster-induced disturbances,achieving coordinated optimization between operational economy and resilience through a modest cost increment and substantial reliability improvement.
