Abstract High proportion of renewable energy sources and power market makes the operation state more variable, so the security correction schemes(SCS) for typical operation mode made offline may be conservative. In addition, in traditional SCS, fast control measures are not considered to avoid further overload during the control process, such as transmission switching(TS), thyristor controlled series compensator(TCSC) control, or multi-terminal direct current(MTDC) power modulation. Thus, a comprehensive security correction(SC) strategy considering the above three fast control measures is proposed based on second-order cone programming (SOCP) to quickly obtain accurate SCS according to current operation mode. Specifically, to ensure the accuracy of SCS, the power flow model with changeable topologically, TCSC and MTDC is constructed based on mixed integer SOCP, and the corresponding SC optimization model is constructed. To ensure the rapidity of solution, a heuristic double acceleration strategy is proposed. Firstly, a heuristic line selection strategy based on the comprehensive influence index of line outage is proposed, thus to reduce the search space. Then, based on the proposed index, an accelerating strategy to induce the objective function is proposed, which further improves the computational efficiency while also guarantee accuracy. Based on the modified IEEE 57 bus system, the effectiveness and accuracy of the proposed SC strategy and its superiority in terms of less load shedding and high solution efficiency are verified.
