Robust Coordinated Dispatch Strategy for the Power System with Large Offshore Wind Power Integration under a Typhoon

The installed capacity of offshore wind farms is growing rapidly, especially in recent years with the accelerated development of offshore wind power in China. The regions with more offshore wind power installations are also areas where typhoons are frequent, and the impact of typhoons on the safe and economic operation of offshore wind farms cannot be ignored. This paper proposes a robustly coordinated operation method of the power system with large offshore wind power integration during a typhoon. The method aims to cope with the uncertainty and disruption caused by a typhoon. The method consists of two parts: a model for orderly cut-off and recovery of offshore wind farms that considers typhoon uncertainties, and a two-stage robust optimization model for coordinated dispatch strategy that is solved by column-and-constraint generation (C&CG) algorithm and strong duality theory. The proposed method is applied to the modified IEEE 39-bus system and the simulation results demonstrate its effectiveness.
