Multi-Objective Planning of Large-Scale Offshore Wind Power Integration System Considering the Cumulative Effects of Typhoons

Aiming at the planning problem of large-scale offshore wind power integration system considering the cumulative effects of typhoons, a bi-level multi-objective planning model of large-scale offshore wind power integration system is proposed. Firstly, the Gumbel extreme value type I distribution and the cumulative impact time of typhoon are adopted to propose the line failure rate under the cumulative impact of multiple typhoons. On this basis, a bi-level multi-objective planning model of large-scale offshore wind power integration system considering resilience improvement is constructed. The upper model aims to minimize the total cost of investment and operation cost, resilience improvement cost, and load loss penalty under the cumulative impact of typhoons. The typhoon weather is regarded as a participant in the game in the planning, and the zero-sum game planning model of offshore wind power integration system planning system is constructed. In the lower model, combined with the line failure rate under the cumulative influence of multiple typhoons, the system resilience is improved by considering the minimum total load shedding of the system during the typhoon transit. A two-stage relaxation algorithm is used to solve the built model. and the two-stage relaxation algorithm is used to solve the model. Taking an offshore wind farm group integration system planning as an example, the simulation is carried out to verify the effectiveness of the proposed model and method.
