This paper proposes a new range of FACTS device based on direct AC-AC conversion, where the modular multilevel AC hexagonal chopper (M2AHC) is employed. The M2AHC is operated in quasitwo-level (Q2L) mode; and the heterodyne modulation is used to decouple voltage amplitude regulation from the phase shift; thus, independent control of active and reactive power is achieved. Then, a family of FACTS...

This paper deals with the loss allocation problem of any interconnected power system. In this paper, an attempt is made to minimize the transmission line loss using FACTS controllers. Two most commonly used FACTS controllers; TCSC and STATCOM are utilized here to reduce the loss. The contribution of system generators at a particular operating load has been calculated using power tracing algorit...

In this paper, the new hybrid particle swarm optimization (hybrid-PSO) based on particle swarm optimization (PSO), evolutionary programming (EP), and tabu search (TS) is developed. Hybrid-PSO is proposed to determine the optimal allocation of multi-type flexible AC transmission system (FACTS) controllers for simultaneously maximizing the power transfer capability of power transactions between g...

We present the design and experimental evaluation of an Optical Multicast System for Data Center Networks, a hardware-software system architecture that uniquely integrates passive optical splitters in a hybrid network architecture for faster and simpler delivery of multicast traffic flows. An application-driven control plane manages the integrated optical and electronic switched traffic routing...

Microgrids (MGs) have emerged throughout the world as major means of integrating a variety distributed energy resource (DER) technologies into distribution system. These DER are mostly coupled through electronic power converters (EPCs). This fact has created new operation challenges these converter-interfaced DERs could compromise MG stability, reliability, and resilience margins. On other hand...
