Abstract:
The fault risk of transformers tends to increase after operating for a long time, which undermines the security and stability of the power grid. In order to improve the security and reduce the economic loss caused by transformer degradation, maintenance of transformers is crucial to operation. Since the maintenance brings an additional cost to the system operation cost, it is necessary to formulate a maintenance strategy that makes a trade-off between maintenance cost increase and system security improvement. This paper describes the transformer states transition with the Markov model, based on which the state probability of transformers in the future periods is forecast. An optimization model for the maintenance strategy is developed, which takes account of maintenance cost, repair cost and potential stochastic load loss. Monte Carlo and optimal power flow(OPF)methods are applied to calculate the potential stochastic load loss. Aimed at guaranteeing a reasonable computing time, a traversal elimination approach is proposed for constructing an optimization model. The case study demonstrates the validity and effectiveness of this model.
