Unified Power Flow Controllers Without Energy Storage: Designing Power Controllers for the Matrix Converter Solution

Advanced Direct Power Control Method of UPFC by Using Matrix Converter

This paper presents a direct power control (DPC) for three-phase matrix converters operating as unified power flow controllers (UPFCs). Matrix converters (MCs) allow the direct ac/ac power conversion without dc energy storage links; therefore, the MC-based UPFC (MCUPFC) has reduced volume and cost, reduced capacitor power losses, together with higher reliability. Theoretical principles of direc...

A New Real Time Lyapunov Based Controller for Power Quality Improvement in Unified Power Flow Controllers Using Direct Matrix Converters

This paper proposes a Direct Matrix Converter operating as a Unified Power Flow Controller (DMC-UPFC) with an advanced control method for UPFC, based on the Lyapunov direct method, presenting good results in power quality assessment. This control method is used for real-time calculation of the appropriate matrix switching state, determining which switching state should be applied in the followi...

Applications of the Direct Space Vector Modulation Controlled Matrix Converter as the Unified Power Flow Controller

This paper investigates the matrix converter when working as the unified power flow controller which can regulate the active reactive power flowing in a transmission line. A conventional unified power flow controller usually has a DC capacitor; this is removed in the proposed controller. This reduces the volume, improves the efficiency and lifetime, and eliminates the DC voltage control. The de...
