In glass furnace boosting, particularly in the tin bath and annealing Lehr heating systems, an AC-AC power converter is normally employed by the industry. This Triac-based converter driven by integral cycle control(ICC) is employed to provide highly accurate power to the resistive heating elements distributed into the furnace. The advantages of ICC include low inrush current and increased reliability; although its impact on power quality(PQ), due to the subharmonic distortion produced, is significant. While different strategies for energy demand management have been implemented to date, they have not adequately addressed this PQ issue. Thus, the goal of this research is to establish an optimal electrical load scheduling strategy considering criteria about PQ and thermal behavior through a mixed-binary quadratic programming(MBQP) problem which exploits the ICC advantages avoiding PQ degradation.

Microgrids are considered as a key technology for the introduction of renewable energy systems in the electrical market. Nevertheless, microgrids are subject to random conditions such as changes in the energy forecast or component failures which will force microgrids to incur in the penalty costs applied in real time markets. In order to minimize the aforementioned costs, an optimal Energy Management System (EMS) for the economic re-schedule of a network of interconnected microgrids with hybrid Energy Storage System (ESS) under failure conditions is developed and validated using Model Predictive Control (MPC). The algorithm is specifically designed to achieve lower economic losses under failure conditions through the establishment of a local energy market in the network of microgrids than participating in the intraday or real-time markets.

Energy efficiency and consumers’ role in the energy system are among the strategic research topics in power systems these days. Smart grids (SG) and, specifically, microgrids, are key tools for these purposes. This paper presents a three-stage strategy for energy management in a prosumer nanogrid. Firstly, energy monitoring is performed and time-space compression is applied as a tool for forecasting energy resources and power quality (PQ) indices; secondly, demand is managed, taking advantage of smart appliances (SA) to reduce the electricity bill; finally, energy storage systems (ESS) are also managed to better match the forecasted generation of each prosumer. Results show how these strategies can be coordinated to contribute to energy management in the prosumer nanogrid. A simulation test is included, which proves how effectively the prosumers’ power converters track the power setpoints obtained from the proposed strategy.

Augmented reality (AR) improves how we acquire, understand, and display information without distracting us from the real world. These technologies can be used in different applications and industries as they can incorporate domain-specific visualizations on a real-world screen. Mobile augmented reality (MAR) essentially consists of superimposing virtual elements over real objects on the screen, to give added value and enrich the interaction with reality. In numerous plants, it is being used for maintenance and repair tasks, as well as training. The Internet of Things (IoT) is increasingly pervading every aspect of our lives, including the power infrastructure of our buildings. IoT-enabled devices offer many connectivity options for helping supervise all-important energy assets. Aggregating data to cloud-based platforms enables operations teams to have on-time information access to make fast decisions and have a fast response regarding energy use, while maintenance teams keep on top of the appliance power quality and reliability needed by using MAR. This paper presents a novel approximation for visualizing appliance-related power quality to enhance awareness about the consumed electricity. A combined solution of MAR with IoT technologies is employed. Engineered solutions’ hands-free way to get data about surrounding appliances reduces the complexity, saves energy, and speeds up the operations. An innovative way to measure things at the right time leads to a competitive advantage.

The effort to continuously improve and innovate smart appliances (SA) energy management requires an experimental research and development environment which integrates widely differing tools and resources seamlessly. To this end, this paper proposes a novel Direct Load Control (DLC) testbed, aiming to conveniently support the research community, as well as analyzing and comparing their designs in a laboratory environment. Based on the LabVIEW computing platform, this original testbed enables access to knowledge of major components such as online weather forecasting information, distributed energy resources (e.g., energy storage, solar photovoltaic), dynamic electricity tariff from utilities and demand response (DR) providers together with different mathematical optimization features given by General Algebraic Modelling System (GAMS). This intercommunication is possible thanks to the different applications programming interfaces (API) incorporated into the system and to intermediate agents specially developed for this case. Different basic case studies have been presented to envision the possibilities of this system in the future and more complex scenarios, to actively support the DLC strategies. These measures will offer enough flexibility to minimize the impact on user comfort combined with support for multiple DR programs. Thus, given the successful results, this platform can lead to a solution towards more efficient use of energy in the residential environment.

Although the power electronics converters involved in glass furnace boosting process may be as diverse as require the electric heating system, in tin bath and annealing lehr heating systems a thyristor based AC-AC voltage converter controlled by integral cycle control (ICC) is often employed, distributed over the multiple heating zones. The ICC is widely used due to its multiples benefits such as low transient current, increased reliability and limited harmonic distortion, but noteworthy at low frequency. The goal of this research is to establish an optimal demand response (DR) and power quality (PQ) strategy using a hybrid technique derived from ICC through a straightforward algorithm characterized by a low computational cost that provides successful results for both thermal stability as well as from the PQ and DR point of view.

There is an outstanding concern from the international standard-setting community about harmonics distortion in the frequency range 2–150 kHz, referred to as supraharmonics. Power electronics has established as a ubiquitous technology, which plays a linchpin role in almost any electrical systems. The classical deterministic pulse-width modulation strategy, entailing at reducing low-frequency harmonics emission (<2 kHz) in power converters, in a sense, bring them to move at the switching frequency and its multiple, in the kilohertz range. The amplitude of spectral components is the main concern when studying electromagnetic interference from active power factor correction stages, included in state-of-the-art LED drivers. Supraharmonics are nowadays the origin of numerous problems in electrical networks. The standardization bodies are presently updating the compatibility limits in the frequency range from 2 to 150 kHz. Supraharmonics behave differently from (lower frequency) harmonics, as reported in the literature. Fortunately, as will be demonstrated in this paper, it is possible to undertake this issue, from the very beginning, by leveraging technologies like random pulse-width modulation. An experimental system based on digitally controlled LED driver has been set up to evaluate the different methods. The algorithms have been implemented on a compactRIO controller incorporating an FPGA and a real-time processor.

In power electronics, deterministic pulse width modulation strategies, aimed at reducing the emission of low-frequency harmonics (<2 kHz), resulting in the transfer of these emissions to the switching frequency and its multiples, in the kilohertz range. The impact of these spectral components is the main concern when studying electromagnetic interference from rectifiers with active power factor correction stage, commonly employed in LED lighting. These so-called supraharmonics (emission in the frequency range 2 to 150 kHz) are at the root of numerous problems in today’s smart distribution grids. Consequently, the standardisation organisations are currently reviewing the compatibility limits within this frequency range. Supraharmonics behave differently from (lower frequency) harmonics, as being reported in the literature. Fortunately, as will be proved further, it is possible to greatly reduce their presence, and at low computational cost, when methods like random pulse-width modulation are properly selected from the very beginning, avoiding the later need to use any mitigation technologies.

The international standardization community is currently reviewing the supraharmonics distortion limits. These are harmonics which fall in the frequency range 2 to 150 kHz. Power electronics has consolidated as a ubiquitous technology, which also plays a critical role in this subject. Broadly speaking, these HF components are due to the normal operation of electronic converters and the switching techniques employed. The paper presents measurements of waveform distortion from several illustrative facilities and loads. Recent studies indicate that future problems to distribution grids may include supraharmonics. Grid-tie inverters are an origin of waveform distortion, still in this frequency range, but, can also be the pillar to mitigate it, when methodologies like random pulse with modulation or modular multilevel converter are properly applied.
