Steady-state analysis of power flow controllers using the power controller plane

This paper presents a new approach whkh simpli6ieS the steady-state analysis and design of power flow controllers (PFC). The method is independent of the size and complexity of networks. It introduces the power controller plane where two fa& d nearly decoupled active power characteristics are defined as a function of the phase angle access the PE%: one for the network and the other for the PFC. Limiting cases of each familia8 are used to define a working area whkh contains ell the operating points of a given PFC and where its most s t d n g operating conditions can be readily identified. With this approach, only a few network cases are needed to perform steady-state PFC studies for both pre- and postcontingency conditions. Because the methad looks at networks from the PFC’s point of view, it simplifies contingency analysis, the design of PFCs and the definition d simple network equivalents suitable for active power flow studies.
