“…Powering a facility or even a single machine recurring to renewable energy strategies is an achieved goal [1]. In the field of renewable energies several relevant research state-of-the-art projects have being conducted to improve efficiency and to rationalize installation costs by introducing several innovative approaches [2], [3], [4] [5], [6], [7], [8], [9] and [10]. All the described goals and innovation achievements supported by data networks for data flow brought along the new introduction of concepts such as Big Data [11], [12] and [13], Artificial Intelligence (AI) [14], [15], [16], [17], [18], Internet of Things (IoT) [19], [20], [21], [22] and [23] and many others.…”

In recent years several efforts have being made in bringing smart network connectivity to the Renewable Energy Plant (REP) environment. On the other hand, REP is extending in scale from specialized points where the energy provider acts as a supplier to home REP (self-energy producers). This enables new important features such as: process automation, monitoring, control and optimizations. On the other hand, and in particular during and after the Covid19 pandemics the cybersecurity menace is a massive concern. The digital literacy of a worker of such an infrastructure is relevant to the correct implementation of adequate security policies. This article describes the threats and challenges on the field and conducts an enquire for perceiving the awareness of Automation and Mechanics Engineering students for this relevant problem, as future player in the field.

“…The energy crisis issue due to the need to reduce CO 2 emissions and the shortage of fossil fuels has led most countries around the world to consider the use of renewable energy (solar PV (photovoltaics), wind power, hydropower, biopower) for electricity production. In 2019, over 200 GW of renewable energy was installed worldwide, including 120 GW of solar PV [1].…”

Comparison between a Cascaded H-Bridge and a Conventional H-Bridge for a 5-kW Grid-Tied Solar Inverter

This paper compares the cost and efficiency of two inverter topologies for a 5-kW grid-connected solar inverter application: the Conventional H-Bridge Inverter (CHB) and the Cascaded H-Bridge Multilevel Inverter (CHBMLI). Emphasis is put on power switches and passive elements with a detailed study of the losses. Both designs respect the same constraints (cost, efficiency, and junction temperature of the transistors) to ensure a fair comparison between both topologies. The work highlights the important parameters when choosing the components (MOSFETs, capacitors, and magnetic cores for the inductors). The DC-link voltage ripple and the output AC current ripple are the key parameters for the design of the passive elements (capacitors and inductors). On top of that, the transistors MOSFETs are chosen, in both topologies, to limit the conduction losses (by selecting the Rdson) and the switching losses (by selecting the Qrr and dv/dt). Real components are picked in order to make the comparison as complete as possible. Numerical simulations are performed using the MATLAB platform. All equations and parameters are provided. A CHBMLI prototype was built with eight independent H-Bridges to validate the proposed design with thermal and efficiency measurements.

“…This would be used for low power consumption electronics. Perhaps no one imagined that so soon, today in 2022, the issue of energy crisis [2] would overwhelm the whole world. Now, the search for methods to use sustainable energy sources (green energy, blue energy) are urgent more than ever at a worldwide level [3,4].…”

The use of textile materials and structures to build textile-based TEGs is of particular interest as they can also offer unique textile properties. In this work, the initial goal is to present a prototype TEG measuring device and its experimental results for comparing the open circuit voltages coming from various pairs of knitted samples which may constitute part of a textile TEG. We focus on representing realistic testing conditions as on a wearable garment, by introducing a friction stage between the contact and separation stages which is applied under a lightweight load. Α second goal is to explore the possibilities of some environmentally friendly textile materials to provide electric energy, again under realistic conditions. From the carried tests, it was seen that even conventional natural knitted textiles structures like single jersey, without expensive and complex nano-treatments, can provide considerable voltages if they are part of a wearable garment. Moreover, it was found that even low friction under a weight load of 20grf is adequate to give the above results. The hereby presented measuring TEG device can be used in the comparison or improvement of textile or even non-textile based TEGs, in order to find optimal combinations of materials and designs to be used on clothing TEGs.
