Advanced modeling of the multicontrol functional static synchronous series compensator (SSSC) in Newton power flow
TLDR
In this paper, a multicontrol functional model of the static synchronous series compensator (SSC) for power flow analysis is presented, which can be used for steady state control of one of the following parameters: (1) the active power flow on the transmission line; (2) the reactive power flow in the power supply; (3) the voltage at the bus; and (4) the impedance (precisely reactance) of the transmission lines.Abstract:
The static synchronous series compensator (SSSC) is one of the recently developed flexible AC transmission system (FACTS) controllers. The SSSC coupled with a transformer is connected in series with a transmission line. This paper describes a multicontrol functional model of the SSSC for power flow analysis, which can be used for steady state control of one of the following parameters: (1) the active power flow on the transmission line; (2) the reactive power flow on the transmission line; (3) the voltage at the bus; and (4) the impedance (precisely reactance) of the transmission line. Furthermore, the model can also take into account the voltage and current constraints of the SSSC. The detailed implementation of such a multicontrol functional model in Newton power flow algorithm is presented. A special consideration of the initialization of the variables of the SSSC in power flow analysis is also proposed. Numerical examples on the IEEE 30-bus system, IEEE 118-bus system, and IEEE 300-bus system are used to illustrate the feasibility of the SSSC model and performance of the Newton power flow algorithm.read more
