| description | Voltage source converter based high voltage direct current transmission is a key method for transmitting large-scale renewable energy generation. The transfer capability of large-scale renewable generation base transmitted by voltage source converter based high voltage direct current system must be considered in modern power system operations. This study introduces an optimal power flow model to evaluate the transfer capability of a renewable generation base transmitted by voltage source converter based high voltage direct current system. The model accounts for the increased transmission capacity of high-voltage direct current lines with load growth, varying voltage-reactive power control characteristics of renewable energy stations, and the switching of control modes when renewable energy stations reach their reactive power output limits. Additionally, considering the reactive power output and voltage characteristics of different reactive power compensation devices, a bi-level optimal power flow model for the optimal configuration of reactive power compensation devices to enhance the transfer capability of the transmission system is proposed. To solve the bi-level optimal power flow model, the Kriging surrogate model is used to obtain the relationship between the transfer capability and the types and sizes of the reactive power compensation devices at the anticipated installation buses, and the inner-layer transfer capability assessment model is replaced with equality constraints, thereby transforming the original bi-level optimal power flow model into a single-layer mixed-integer nonlinear programming model for direct resolution. Finally, the effectiveness of the proposed model and solution method is validated using a real transmission system in South China. |
