In the islanded microgrid with a high proportion of new energy, the intermittency and volatility of wind power will increase the uncertainty of the operation and dispatching of the microgrid, which may affect the safety and stablility of the system operation in serious cases. Therefore, an operation strategy of offshore island microgrid considering demand side management of user comfort is proposed. Firstly, the fine modeling and differentiated demand response strategies are carried out for different types of load users in the microgrid, and the evaluation indexes of different types of users are proposed. Then, the day-ahead scheduling framework is established to optimize the user comfort and minimize the daily operation cost of the microgrid, and the day-ahead scheduling plan is obtained by using yalmip+cplex solver. Finally, an offshore island microgrid is taken as an example to verify the effectiveness and universality of the proposed strategy in different wind power scenarios.
