The centralized power grid bears a heavy burden in time when consumers expect an uninterrupted reliable supply, reduction carbon emissions, increased efficiency within the national grid, and supplied to remote communities. One such structure is used implement this type of control that based on small- scale Distributed Generation (DGs), at single house or small building level: micro-grid (μG). A...

This manuscript applies model prediction-based control (MPC) to accommodate the variable ac-natured load (AL) by optimally allocating fuel cell (FC), battery, solar photovoltaic (SP) power in a four-port dc/dc converter (FPDDC). The presented work considers FC, SP, and AL at first, second, third, fourth ports of FPDDC, respectively. small signaled state-space representation FPDDC has been obtai...

A smart distributor system for controlling a micro grid has been developed in this work. The switches ON different generators one after the other as consumer load demand increases or them OFF decreases. This was achieved using microcontroller, current and voltage transformer. microcontroller programmed embedded C-language to communicate with transformers give necessary output signals activate d...

The functioning of local electric networks ('Micro Grid') is described, which due to the development Smart Network technologies, distributed generation and electricity storage systems received an incentive for development. structural decomposition market model suggested 'Top-Level Market' 'Micro Grid' reflect interaction with wholesale market. Load regulation instruments are ensure flexibility ...

this paper proposes a flexible power electronic transformer (fpet) for the application in the micro-grids. the low frequency transformer is usually used at the point of common coupling (pcc) to connect the low voltage grid and utility network to each other. the conventional 50hz transformer results in enhanced low voltage-grid power management system during grid-connected operation. in this pap...

There are still residents without access to electricity in some remote and less developed areas of China, which lead to low living standards and hinder sustainable development for these residents. In order to achieve the strategic targets of solving China’s energy poverty, realizing basic energy service equalization, and comprehensively building up a moderately prosperous society, several polic...

This paper presents an improved controller for the dual topology of the unified power quality conditioner (iUPQC) extending its applicability in power-quality compensation, as well as in micro grid applications. By using this controller, beyond the conventional UPQC power quality features, including voltage sag/swell compensation, the iUPQC will also provide reactive power support to regulate n...
