Abstract: Abstract:Based on the static model of synchronous static series compensator (SSSC), the influence of SSSC on power grid was translated into the equivalent injected power on the nodes. The relation between the node injected power and SSSC control parameters was deduced. According to given power control target, new state equation was established, and a power flow calculation method for power grid containing SSSC under condition of given power control target was proposed. In the calculation process of the method, it is not needed to modify the original grid node admittance matrix. Based on original grid power flow equation, the new state variables were selected, and the influence of SSSC on the power grid was transferred to the amendment of the power flow equation. The effectiveness of the method was verified by practical example.
