From the perspective of global warming mitigation and depletion of energy resources, renewable energy such as wind generation (WG) and photovoltaic generation (PV) are getting attention in distribution systems. Additionally, all electric apartment houses or residence such as dc smart houses are increasing. However, due to the fluctuating power from(More)
Recently, a smart grid has been attracted attention from the background of the introduction promotion of natural energy. At present, a smart grid based on AC grid has been proposed. However, no paper or article has been presented or published on a smart grid based on DC grid. This paper presents a AC/DC hybrid power system. The system has advantages on both(More)
This paper presents a novel control strategy based on variable structure theory (VST) for the generator side converter to regulate the dc link voltage of a direct driven PMSG wind energy conversion system (WECS). The validity of the technique is theoretically analyzed, and the design procedure is presented. The primary merit of the proposed technique is(More)
This project deals with a grid connected wind-PV hybrid distributed generation system employing permanent magnet synchronous generator(PMSG) driven by a variable speed wind turbine and PV array connected to a load and the grid. PMSG wind turbine connected to a dc-dc converter via three phase diode rectifier and PV array along with a dc-dc converter(More)
