Dynamic Simulation Study of the Whole Process of Isolated Network Operation Considering New Energy Connection
In view of the outstanding problems of isolated grid operation and stability control,combining with the real case of passive isolated grid operation and loss of voltage in a southern region,this paper constructs a full electromagnetic transient simulation model which is consistent with the actual grid,and carries out dynamic inversion of the whole process of isolated grid operation,which completely reproduces the action characteristics of the various stages of the field accident.It also studies the impact of new energy access on isolated grid stability and analyzes the influence of high voltage ride-through characteristics of the wind farm on isolated grid operation.Then it proposes the operation strategy that increasing the proportion of wind power is conducive to reducing the frequency peak after the regional power grid passively enters the isolated grid.Through simulation verification,the paper proposes a general method for dynamic analysis of isolated grid considering new energy access.
