The operation of Fuel Cell Distributed Generation (FCDG) systems in distribution systems is introduced by modeling, controller design, and simulation study of a Solid Oxide Fuel Cell (SOFC) distributed generation (DG) system. The physical model of the fuel cell stack and dynamic models of power conditioning units are described. Then, suitable control architecture based on fuzzy logic contro...

abstract: one the most important problems in recent sensitive loads is the quality of voltage. for this challenge custom power devices are used in distribution systems. dynamic voltage restorer (dvr) is a custom power device that improves voltage, decrease power distortion, filter harmonics and balance distributed generations (dgs) with low voltage distribution system. in this paper, a new algo...

Harmonic currents are introduced into power system as use of nonlinear electrical loads increases. Extra losses caused by harmonic current stream effective supply lines. A dynamic filter engenders compensating using a switching inverter. Single-phase the connects in parallel to load end and inject required feeder avoid direction system. This report discusses problem, available mitigation techni...

Grid-connected inverters is the core component of distributed generation system, and filter inverters. When inverter works, can effectively suppress high-frequency harmonics in output current side, so as to ensure stability power grid improve working effect whole connected system. The a high order underdamped LLCL Filter also has resonance peak. In this paper, weighted method based on active da...

this paper presents a comparative analysis between two current control strategies, constant source power and generalized fryze current, used in active power filter (apf) applications having three different modulation methods. the hysteresis band (hb) and first-order delta-sigma modulation (dsm) as well as the second-order dsm is applied. the power section of the active power filter is viewed as...

This paper demonstrates an enhancement of power quality in grid integrated systems with the help of the proposed control strategy for voltage source converter based active power filters. The Shunt Active Power filters (SAPF) are extensively utilized in modern grid integrated systems to diminish the power quality concerns associated with it. The SAPF is one of the various power filters, which ha...
