Control of Fuel Cell Distributed Generation interface to mitigate voltage disturbances in distribution system
This paper presents controller design and simulation study of a Fuel Cell (FC) Distributed Generation (DG) interface to mitigate voltage disturbance in distribution systems. The fuzzy sliding mode controller design for the voltage source converter is presented to control the reactive power and voltage disturbance mitigation in the utility grid. According to the developed MATLAB/Simulink simulation model for the FCDG system, simulation results are given to show voltage regulation capability of the proposed control strategy in distribution system.
A number of multifunction sensors deployed randomly with limited energy is one character of wireless sensor networks, so energy efficient is a critical factor in sensor network design. In this literature, we present a clustering protocol based on Virtual Area Partition using Double Cluster Heads scheme (VAP-DCH) for wireless sensor networks, which partitions the network and selects a Main Cluster Head (MCH) and a Vice Cluster Head (VCH) in each cluster adaptively. The simulation results show that the protocol we presented improves the system performance, prolongs the network lifetime and transfers more data to the base station..
