Modeling of static synchronous series compensator in Newton power flow calculation in PSASP

This paper investigated a model of SSSC in power flow calculation which considering characteristic of injected voltage of SSSC and the control constraints of inverter in Newton power flow analysis in PSASP (Power system analysis software package). The key problem for developing a suitable model of SSSC for power system and power flow calculation in bulk power grid is resolved. The UD (User-defined model) and UPI (User program interface) function of PSASP have been used for generating the controllable injection voltage. The modeling could provide both capacitive and inductive compensation through regulating phase angle of injection voltage. The analysis results based on EPRI-7 system are presented to demonstrate the performance of SSSC power flow model and the satisfactory steady state performance also shown the effective regulation of SSSC
