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.

Power quality (PQ) has been increasing interest in recent years due to the high integration of sources of distributed generation (DG) in the electricity market. This interest has led a considerable amount of research into early detection of faults and their in processes in operation. This paper presents the design and implementation of an educational platform based on embedded electronic systems to operate in real time in DG framework. We contend that the causal relationship between building model solutions and developing products from these solutions provides a sound basis for industrial strength software engineering. The proposed test bench enables both undergraduate and graduate electrical and electronics engineering students to analyze the modelling techniques developed for event analysis. The architecture has been specially configured to assess the efficiency of algorithms when they are executed in real time. A case study, as well as the experimental results, are presented, which show and address the performance of the educational platform.

To determine temperature losses in a photovoltaic (PV) installation, the operating temperature of the cells in the PV panels must be known. This temperature cannot be directly measured because the cells are not accessible from the outside, as they are inside the panels, with other layers of material surrounding them. Therefore, the parameter to which direct access exists by means of measuring is the temperature of the outer surfaces of the modules. However, the cell junction temperatures are typically 1–3 °C higher than the temperature measured on the module's rear surface, depending on the module construction. Some methods exist for determining the cell temperature, including measuring the open-circuit voltage of the panels, but because this is difficult to do with an on-site PV installation, normally this temperature is determined by using models. Numerous models appear in the literature for determining the cell temperature, so in this paper, a recompilation of twenty models is taken into account for determining the temperature and miscellaneous losses of a PV installation located in South Spain in a year’s time. These models have different relations between the value of the cell temperature and some environmental parameters, considering or not the value of the wind speed and the form in which the panels are installed. A maximum difference in annual temperature losses found using the twenty models was 90.4 h/year. This non-negligible quantity indicates the importance of an appropriate choice of model and the correct conditions for applying it to make a precise estimation of the capture temperature losses. Moreover, it would be interesting to reach an agreement on the best procedure for determining this type of losses, especially for correctly performing comparisons of these losses in different PV plants in operation, which can reach very significant values in locations with high temperature registers.

Wireless sensors networks have an enormous potential for measuring environmental parameters such as those found in building or residential scenarios. The range of available sensors is not only limited temperature, gas, humidity or presence detection, but even power grid analyser can be integrated. This work aims to develop a Home energy management system for a residential scenario or nanogrid. Inside this nanogrid and using short term power availability together with demand response techniques, the system will be able to control and schedule the main domestic loads such as heating, air conditioning and ventilation systems, white goods or lighting among others. The control system is designed following the latest machine-to-machine (M2M) communication trends and standards defined by the oneM2M consortium. Thus, a first approach to the Message Queue Telemetry Transport (MQTT) protocol is presented as a means of developing a smart home appliances control using devices with limited resources.

This chapter has justified the choice of the PTP standard for coordinating all of the equipment located in an installation as the most appropriate way of extending it to other installations in a wide geographical area. It is possible to reduce the amount of equipment equipped with GPS, but guaranteeing the synchronism with a quality equivalent to 1 ms. An intelligent network must evolve dynamically according to demand. In this context, it is essential to maintain a control of the stability of the network in a greater number of control points. The current technology has lowered the costs of high-performance electronic systems. As discussed in this chapter, PMUs or synchrophasors are an essential piece, and their integration into the IEC 61850 standard allows a local and centralised management system to be defined that cooperates with other systems located in the network, such as SPQAs and intelligent inverters.

This paper presents a novel system which has been developed to supervise in real time the operation of a Grid-Connected Utility-Scale PV Power Plant in order to ensure a reliable and uninterruptible power supply. The system is composed of a complex acquisition architecture which measures the required information with a high temporal resolution and using a high-precision protocol for synchronizing all the devices, something strictly necessary for accurately establishing a relationship among all events taking place in the plant. Moreover, an advanced system for monitoring and supervising all the distributed devices, as well as for the real-time treatment of all the registered information is presented. This system does not only enable a better control over the performance of all the PV plant's components by detecting any failures or deviations in production, but it also monitors the power quality of the injected signal and its influence on the distribution grid.

Smart grids play an important role in the development and modernization of the electric power system. Smart grids deal with the integration of information technology and the electric grid. In this context, a communication system is needed to achieve the main goals of smart grids. Interoperability between the systems has become an important issue. To achieve this, the IEC 61850 standard models the electric power system by means of a hierarchical data model based on semantics definitions. Existing and future applications for the electric power system heavily depend on the performance of the communication system. Several factors can affect the performance of the IEC 61850 communications. Previous studies have already analyzed the influence of network related aspects. In this research, some factors related to data and data modeling of IEC 61850 have been identified that influence the performance of the IEC 61850 devices, through the processing time. The study presented in this paper analyzes them and proposes practical recommendations to optimize the performance of the system. The results obtained reveal the importance of a proper use of data sets because their influence over the communications performance.

The electricity sector is undergoing an evolution that demands the development of a network model with a high level of intelligence, known as a Smart Grid. One of the factors accelerating these changes is the development and implementation of renewable energy. In particular, increased photovoltaic generation can affect the network’s stability. One line of action is to provide inverters with a management capacity that enables them to act upon the grid in order to compensate for these problems. This paper describes the design and development of a prototype embedded system able to integrate with a photovoltaic inverter and provide it with multifunctional ability in order to analyze power quality and operate with protection. The most important subsystems of this prototype are described, indicating their operating fundamentals. This prototype has been tested with class A protocols according to IEC 61000-4-30 and IEC 62586-2. Tests have also been carried out to validate the response time in generating orders and alarm signals for protections. The highlights of these experimental results are discussed. Some descriptive aspects of the integration of the prototype in an experimental smart inverter are also commented upon.

The non-dispatchable, intermittent and unpredictable nature of photovoltaic energy has made its integration in power system very limited. This paper presents a system for monitoring, supervising and treatment of the information in real time applied to photovoltaic plants connected to the grid. Experimental results shows the usefulness of the system implemented for monitoring a grid-connected photovoltaic park production in real time, ensuring the synchronization of the magnitudes with high precision. This study demonstrates how the operation and maintenance of a photovoltaic plant and in general any renewable facility connected to the grid may be considerably improved by the use the proposed real time approach. With this functionality, the photovoltaic parks will become active parts of the grid, contributing to the massive integration of distributed generation in the smart grid.

IEC 61850 is one of the crucial standards within the Smart Grid concept. For performance evaluation of communications between Intelligent Electronic Devices (IED) in Power Utility Automation, the standard defines the Transfer Time. Measurement of such parameter is not available for end user, but in development stage it is possible. Third party products can be used to reduce development time of IEC 61850 compliant devices. An initial performance evaluation of these products can be achieved through the measurement of the Transfer Time.

This paper describes an Embedded System (ES) for an inverter. In recent years, there is a worldwide interest in Distributed Generation (DG). This is due to the need to integrate renewable energy sources into the Distribution System. This paper proposes the development of a platform to the safe and intelligent management of the DG in the grid. The proposed system requires a platform to integrate, among others, innovative technologies of processing multifunctional, synchronization and communication, in a way that to perform the requirements of DG grid connection. The work here deals with the detection of power quality events, in particular sags, swells, transients and faults. Different statistical estimators have been used (skewness and kurtosis) to enhance characterization of these anomalies. Additionally, a real-time CUSUM algorithm for early detection of these events, have been implemented.

Present distribution networks have not been designed to accept extensive Distributed Generation (DG). The present framework may change in the near future impelled by a worldwide increase in DG penetration in distribution grids. The mutual dependency of energy distribution and communications on the same grid requires new means for effectively monitoring and controlling both systems in parallel. Relaying and control IEDs can also serve as measurement units for power quality. Synchronized Measurement Technology (SMT) has the potential of becoming the backbone of this paradigm. By using wide-area information systems, the data can be made available to all involved partners. This paper provides different outlooks about the possibilities of Embedded Systems to integrate the protection, control and monitoring functions in Distribution Automation Systems. To justify the choice of synchronization technology, we have scheduled a complete sequence of synchronism tests and measurement tests based on standard specifications.

The main objective of this paper is to describe a technique for optimize the capturing and processing of voltage and current signals at various points of the power system. The FPGA enables parallel processing of multiple signals. We present preliminary results with FPGA-based embedded system architecture for six-processing signals. A second objective is use of Precision Time Protocol to Synchronise Sampled Value with high precision. Therefore, we use a Software Based IEEE 1588-2008 for synchronization of the captures of event for Power Quality measurements.
