Research on the DC access grid security and stability analysis

This article research on the DC access grid security and stability analysis. It combed the stability and security of electrified weak link, revealing the power grid dynamic characteristics of evolution mechanism. It study and formulation of reservoir in the power grid security and stability control strategy of DC power transmission system, the access of power grids in Tibet, AC / DC hybrid power grid by the end of security and stability control measures. The conclusion of the study, for reservoirs in AC DC hybrid power grid by the end of the safe and stable operation and control measures for reference to make the reasonable.
