“…Modern power system includes different types of loads, to classify broadly, DC and AC. These loads are supplied through the nanogrids by efficiently interfacing and regulating the different energy sources (renewable and non-renewable), using power electronics [1]. Local renewable energy sources like solar photovoltaic (PV) generate a DC output which is then converted to suitable values of both AC and DC outputs.…”

“…In the past few decades, the emphasis on exploiting renewable energy resources has grown steadily. To incorporate the energy generated from these resources into the existing system, nanogrid and microgrid architectures were proposed [1, 2, 3, 4, 5]. The applications of these architectures have been increasing ever since, in modern electrical power systems [6].…”

This study proposes a novel buck-boost based interleaved hybrid converter (BIHC), which can supply both AC and DC loads simultaneously. This topology uses two buck-boost derived hybrid converters where the DC outputs of the individual converters are interleaved and the AC voltage is the differential voltage tapped between the two source (of the MOSFETs) nodes of the individual converters. This converter uses only two switches which is lower than similar converters reported in literature, hence reducing the switching losses. In BIHC, there is no possibility of shoot through and no dead time compensation is required. BIHC will find application in hybrid nanogrids supplying residential loads powered by solar photovoltaic. The principle of operation of individual converters is augmented sinusoidal pulse width modulation with AC references for individual converters phase shifted by 180°. This results in line frequency components in the inductor currents and hence the buck-boost stage inductors are relatively larger. However, reduction in number of switches offsets this increase in size. The circuit has been extensively simulated in MATLAB and an experimental prototype of 100 W is tested in the laboratory.

“…Numerous research activities are currently being undertaken to mitigate the fluctuation and oscillation of the delivered power to provide stable power supply solutions through these smart grids [10][11][12]. The authors in [13,14] have discussed the concept of nanogrid and their integration technologies. Further authors also defined nanogrid as small modular load blocks corresponding to low-power management within a given microsystem and in managing a set or a point load [15,16].…”

Integrated Nanogrid for the Impressed Current Cathodic Protection System in Desalination Plant

2023

The impressed current cathodic protection (ICCP) scheme is a more reliable and efficient method of corrosion prevention mechanism than the sacrificial method. Currently, the grid connected transformer rectifier units supported with a battery banks are used for the ICCP-based corrosion protection system in the desalination plant. This conventional method is entirely grid-dependent, more expensive, and suffers during prolonged grid failure. The present trend of industrialization is the application of multi-renewable energy sources based on a nanogrid to power the station’s auxiliary power supply. This paper introduces a concept of distributed energy resources (DERs) operated integrated nanogrid (ING) system to provide a stable power supply solution to the ICCP scheme. A 100-million-litter per day capacity-based seawater desalination plant (SWDP) in India has been chosen as the test station. The conceptual hardware design and operational logic details for smooth integration of the integrated nanogrid module into the ICCP scheme of the Desalination plant is proposed. This research aims to investigate the behaviour of DERs during on-grid, off-grid and switching over from one mode of operation to another and vice-versa by using the accelerated Gauss–Seidel method in ETAP software (version 16.0.0). The simulation results confirm that the ING suffers from a high-frequency change rate during islanded operation, and in some cases, a complete blackout occurs. A PLC-based Smart Versatile ING Controller has been suggested to overcome the blackout issue. Finally, it has been proven that the stability of an industrial power system can be improved further by introducing the ING module into it.
