Power system stability improvement using (SSSC)‎

الملخص EN

In this paper the impact of one type of Flexible AC Transmission Systems (FACTS) devices which
is called Static Series Synchronous Compensator (SSSC) for improving power system stability is
developed.

The optimal location of (SSSC) is determined related to deregulated electricity market
to reduce system losses and congestion of the transmission line, hence increasing maximum load
ability of the system.

The congested line based on optimal power flow (OPF) tool to find local
marginal price (LMP) difference is determined.

A list is formed based on the magnitude of the
difference in (LMPs) to find the most congested lines.

For each line in the priority list the
continuation power flow (CPF) is determined with (SSSC) in that line, the best location of (SSSC)
is the one where by placing (SSSC) gives highest maximum loading point.

The results showed that
proposed location of (SSSC) in congested line give higher maximum loading point and improve
system dynamic performance.

The study is illustrated on IEEE 14-bus system, based on Power
SystemAnalysis Toolset (PSAT).
