Modelling and Performance Analysis of Distributed Power Flow Controller Using SIMULINK

Power flow control is a big challenge in power systems. Therefore, integrated FACTS devices: STATCOM and SSSC i.e. UPFC is the most suitable device for this application. However, due to cost and reliability issues, researchers have suggested an advanced compound FACTS device which is originated from UPFC with employment of distributed FACTS concept. The latest concept is Distributed Power Flow Controller (DPFC). This paper focuses mainly on state modeling and controlling of DPFC in d-q frame which includes series controller, shunt controller and DC bus voltage controller. Further, DPFC deployed system performance is analyzed for different cases through simulation. The discussed control scheme facilitates the DPFC to manage real and reactive power flow in power line freely. In conclusion, simulation results indicate the potency and soundness of modelling and control schemes of DPFC for power flow governing.
