摘要：
The existing summer emergency scheduling strategies of post-disaster distribution network generally reduce economic losses from the perspective of maximizing power conservation，and do not directly measure the cooling value，leading to high load guarantee cost. Therefore，an electric-cold load guarantee strategy of post-disaster distribution network with hybrid mobile energy storages is proposed. A novel load guarantee architecture is constructed，which aims to use mobile electric energy storage to charge and discharge in different places and mobile ice energy storage to transfer the stored ices among the ice storage air conditionings to cooperatively guarantee the load energy consumption. The space-time transfer and energy change characteristics of mobile electric energy storage and mobile ice energy storage are quantitatively analyzed，and a simplified collaborative operation model of hybrid mobile energy storages is constructed. On this basis，aiming at the sum of penalty costs of power load and cooling load shedding，a load guarantee model of distribution network considering power flow constraints is proposed. The optimization model is transformed into a classical mixed-integer second order cone programming problem for efficient solution. The simulative results of the example verify the rationality and feasibility of the proposed strategy. © 2023 Electric Power Automation Equipment Press. All rights reserved.
