Power flow modeling/calculation for power systems with Dynamic Flow Controller

This paper presents a new procedure for power flow calculation of power systems in presence of dynamic flow controller (DFC) which is a new member of FACTS controllers. The focus of the paper is to explore how to systematically extend and modify Newton-Raphson power flow method to include DFC. A new steady state model of DFC is introduced for the implementation of the device in the conventional Newton-Raphson power flow algorithm. The impact of DFC on power flow is accommodated by adding new entries and modifying some existing ones in the linearized Jacobian equations of the same system without DFC. A case study on North of IRAN power system shows the effectiveness of proposed method.
