基于预演算法的灾后配电网应急抢修决策优化
Rollout Algorithm-Based Post-Disaster Distribution System Emergency Repair Optimization
摘要
Abstract
In order to cope with the loss from power outages caused by extreme disasters,it is necessary to construct a reasonable post-disaster recovery model and explore effective post-disaster emergency decision-making methods.In this study,a Markovian decision process model for post-disaster emergency recovery considering critical load failure events is constructed.It also considers the impact of outage duration on the functionality of different types of critical loads when calculating the losses.For post-disaster emergency decision-making,an online decision-making method based on a preview algorithm is proposed to quickly evaluate the action-state value function(i.e.,Q function)by means of multi-scenario simulation and generate an online optimization strategy.It is demonstrated that the decision scheme based on the Q function generated by the rollout algorithm is better than that provided by the underlying strategy in the simulation.The proposed method does not rely on precise mathematical models and parameters and can update the policy in real time according to the system state,which is a more practical approach than that of the traditional offline optimization model.关键词
