摘要：
Splitting control, the third defense for the stability control of the power system, ensures the stale operation of the power grid with minimal costs after a severe fault disturbance. The existing splitting control strategies are mainly divided into the traditional out-of-synchronization splitting based on the positioning of the grid out-of- synchronization oscillation center, and the predictive active splitting based on the measurement of grid fault scene information. This paper proposes a splitting method for the sending-end AC power grid based on a mixed-integer second- order cone programming. Its main contents include: 1) by transforming the system's nonlinear power flow equations into linear equations through relaxation means, the power flow solution can be obtained by solving the second-order cone programming problem; 2) through establishing a power grid splitting model based on the mixed-integer second-order cone programming, the splitting section is solved with the goal of minimizing the unbalanced power to ensure the safe and stable operation of the transmission-end power grid. Simulation results demonstrate the effectiveness of the proposed approach. © 2022, Power System Technology Press. All right reserved.
