Power line communication (PLC) is increasingly emerging as an important communication technology for the smart-grid environment. As PLC systems use the existing infrastructure, they are always exposed to conducted electromagnetic interference (EMI) from switching mode power converters, which need to be tightly controlled to meet EMC regulations and to ensure the proper operation of the PLC system. For this purpose, spread-spectrum modulation (SSM) techniques are widely adopted to decrease the amplitude of the generated EMI from the power converters so as to comply with EMC regulations. In this paper, the influence of a spread-spectrum-modulated SiC-based buck converter on the G3-PLC channel performance is described in terms of channel capacity reduction using the Shannon–Hartley equation. The experimental setup was implemented to emulate a specific coupling path between the power and communication circuits and the channel capacity reduction was evaluated by the Shannon–Hartley equation in several operating scenarios and compared with the measured frame error rate. Based on the obtained results, SSM provides the EMI spectral peak amplitude reduction required to pass the electromagnetic compatibility (EMC) tests, but results in increased EMI-induced channel capacity degradation and increased transmission error rate in PLC systems.

Power line communication (PLC), which is often used in advanced metering infrastructure (AMI), may be disturbed by adjacent high-power converters. Due to the inherent features of this type of communication, classic methods of improving communication reliability (filtration and circuit separation) cannot be fully applied. Information coding (modulation) methods are used in PLC to increase the data transfer rate and improve noise immunity. Random modulations (RanM) are used in converters to lower emission levels. Therefore, we investigate how the converters’ modulation parameters and coding methods may affect PLC communication reliability in the paper. To this end, we employ an experimental approach. In particular, the analysis of the influence of deterministic modulation (DetM) and (RanM) on the performance of narrowband G3-PLC is shown. We emulated an actual situation where EMI generated by the DC/DC converter disturbed the PLC transmission. The experimental results show the transmission error rates for different operating scenarios. The natural (experimental) system results, due to the complexity of the disturbing signals, differ from the literature data obtained by simulation for normalized signals.

The assessment of electromagnetic compatibility (EMC) is important for both technical and legal reasons. This manuscript addresses specific issues that should be taken into account for proper EMC assessment of energy systems that use power electronic interfaces. The standardized EMC measuring techniques have been used in a laboratory setup consisting in two identical DC/DC converters with deterministic and random modulations. Measuring difficulties caused by the low frequency envelopes, resulting from frequency beating accompanying aggregation of harmonic components of similar frequencies, were indicated as a phenomenon that might lead to significant problems during the EMC assessment using currently binding standards. The experimental results describing deterministic and random modulated converters might be useful for practitioners implementing power interfaces in microgrids and power systems as well as for researchers involved in EMC assurance of power systems consisting in multiple power electronic interfaces.

An assessment of electromagnetic compatibility is important from a technical as well as legal point of view. The harmonized standards should provide detailed guidelines enabling assessment of electromagnetic compatibility for the typical application of devices in systems. This paper presents the specific issues accompanying measurements of conducted electromagnetic interference in multiconverter systems. The theoretical considerations have been confirmed by experimental results obtained in a laboratory and in a real 1 MW photovoltaic power plant. The presented theoretical and experimental results might constitute the recommendations for practitioners dealing with conducted interference measurements, while the proposed approach can be used as a basis for the elaboration of reliable standards for electromagnetic compatibility assessment in multiconverter systems within the scope of the studied interference frequency range.

Field-Programmable Gate Array (FPGA) provides the possibility to design new “electromagnetic compatibility (EMC) friendly” control techniques for power electronic converters. Such control techniques use pseudo-random modulators (RanM) to control the converter switches. However, some issues connected with the FPGA-based design of RanM, such as matching the range of fixed-point numbers, might be challenging. The modern programming tools, such as LabVIEW, may facilitate the design process, but there are still fixed-point operations and limitations in arithmetic operations. This paper presents the design insights on the FPGA-based EMC friendly control system for DC/DC converter. Probability density functions (PDF) are used to analyse and improve pseudo-random algorithms. The theoretical algorithms, hardware details and experimental results are presented and discussed in terms of conducted electromagnetic interference emission.

However, the theoretical analyses as well as experimental results have indicated that ostensible reduction of the EMI level generated by random modulated converters results from the methodology of the EMI spectrum measurement, adopted in currently binding standards, rather than physical nature of interference generation phenomenon. The experimental investigations, presented in the paper, have shown that utilization of commonly used EMI measuring standards might lead to wrong conclusions in a case of assessment of electromagnetic compatibility of random modulated converters. The aim of this paper is to propose the novel, efficient method enabling objective evaluation of the EMI generated by random modulated converters.

Cyber-Physical Power Systems integrate the various devices which provide ancillary system services. In this paper, the design and implementation of a fully controllable cyber-physical system is presented. This system simulates the behavior of the real power system and additionally assures controllable, repeatable testing conditions, enabling investigations of energy storage systems. Ancillary system services provided by energy storages are especially crucial in the context of renewable energy sources and electromobility sector development. Credible tests of control strategies, realizing system services, require controllability of test parameters. Such investigations are impossible in a real power system, due to its inherent variability. The novel approach presented in the paper enables management of power system resources supplied by various producers and ensures flexibility in the realization of assumed scenarios of power system operation. Such an controllable cyber-physical power system constitutes a suitable environment for tests of the effectiveness of ancillary services provided by energy storage systems, because the system is independent of inherent variability of the real power system and enables flexible realization of the control algorithms developed for all of the system components (power source, loads and energy storages). The voltage profile improvement in low voltage grids has been shown in a case study confirming the applicability of the proposed approach.

The concept of demand response (DR) is relatively well-known. There is an extensive literature on possible DR system services and evaluation of regulative potential, based on statistical analyses of data concerning loads suitable for provision of the service. Some of the presented concepts have been implemented in real applications. However, as far as the authors know, this paper presents the first attempt at an implementation of a decentralized active DR system (DADR), without communication between devices, in the form of a laboratory setup consisting 1000 devices enabling primary regulation support. The proposed implementation covers an original hardware design, a software platform for flexible system development, a laboratory arrangement enabling an objective assessment of the quality of service provided by the DADR system, as well as results of a pilot test in real power system. The practical realization of the DADR system is based on an earlier elaborated and theoretically investigated control algorithm, presented in previous papers.

Random modulations are treated as one of the solutions for reducing conducted electromagnetic interference (EMI) in power electronics inverters. Although in papers related to inverters, this view has not been clearly demonstrated. Especially in the state-of-the-art papers related to randomly modulated inverters, it is hard to find information about EMI measurement procedures or deeper EMC analyses. Therefore, this paper will discuss the influence of random modulations used in power electronic inverters on selected issues related to inverter EMC and power quality. A complete case study is carried out on a three-phase inverter. The undertaken analysis refers to the generation of interference, EMI measurement methodology, the conditioning of EMI filtration, and the quality of output voltage. The results show which EMI parameters are improved and which parameters are aggravated, when random modulation is used. The presented results show that random modulation should be applied in inverters with great caution. In addition, we show the limitations of EMI measurement methods and propose a more reliable way to assess the EMI spectrum.

The assurance of the electromagnetic compatibility of sensitive smart metering systems and power electronic converters, which introduce high-level electromagnetic interference is important factor conditioning reliable operation of up to date power systems. Presented experimental results have shown that currently binding, frequency domain tests are ineffective for the evaluation of data transmission error hazards. The proposed in this paper mathematical, time-domain model, based on Diophantine equation, enables evaluation of data transmission errors caused by interference introduced by DC-DC power electronic interfaces with deterministic modulation. In the paper there have been presented possible application areas for the proposed model.

In the paper a new control method for the five-level cascaded inverter is presented. The proposed control method allows full regulation of energy collection from a particular DC voltage source. Application of the cascaded inverter with the proposed control brings many benefits to the DC/AC energy conversion with several DC sources. These benefits are: reduction of the emission of electromagnetic disturbances, an increase in the efficiency and power quality at the output of the inverter.

Reliable operation of the smart grid requires assurance of the electromagnetic compatibility of sensitive smart metering systems and power electronic converters, which introduce high-level electromagnetic interference. As it has been experimentally shown, currently available, normalized, and frequency domain tests are ineffective for the evaluation of data transmission error hazards. The mathematical time-domain model proposed in this paper enables assessment of the probability of errors occurring in a given transmission signal for known interference parameters. The validity of the model and its practical applicability have been experimentally verified.

According to the EMC Directive 2004/108/EC requirements: “where an apparatus is capable of taking different configurations, the electromagnetic compatibility assessment should confirm whether the apparatus meets the protection requirements in the configurations foreseeable by the manufacturer as representative of normal use in the intended applications”. However there are no precise descriptions of how to evaluate the electromagnetic compatibility of a system consisting of many interference sources, neither in the EMC Directive nor in the harmonized standards. The aim of this paper is to evaluate the aggregated interference caused by a group of power electronic converters [1] using a simplified model of DC/DC converters and Pearson’s random walk approach.

In the paper multilevel inverters with common mode (CM) voltage compensators are recommended as voltage sources that can constitute the main components of the energy balancing systems for end-user customers. These systems are a part of the modern LV and MV smart grids [1-3]. Measurements have been provided from a power system consisting in multilevel inverters and a passive compensator assuring sinusoidal output voltages and zero CM voltage [4]. The presented theoretical analyses and experimental results show that the main application problem with magnetic saturation of the CM choke becomes less important in multilevel inverters with specially selected modulation. This allows a reduction in size, weight and cost of inductive components of compensators in such applications.

Purpose – The purpose of this paper is to evaluate the conditions in which a saturation of the common mode (CM) choke might appear to be essential for proper design of the CM voltage filters. This paper presents a method for the determination of a CM choke flux density produced by multilevel inverters with carrier-based modulations. Design/methodology/approach – The proposed combination of secant and tangent methods allows efficient and high-resolution determination of the CM voltage waveforms produced at the output of the multilevel inverters with commonly used carrier-based modulations. Findings – The presented results show that the application of a five-level inverter with specific modulation causes a decrease of the maximum flux density, down to 15 per cent of the maximum level of the flux density reached in a two-level inverter. The proposed, dedicated approximation method provides an accuracy of the root estimation better by about three orders for a comparable number of the function calls in comparison with Brent's method. Practical implications – The presented theoretical evaluations make possible the determination of the maximum expected value of the flux density produced by multilevel inverters with various types of carrier-based modulations, which allows a reduction in dimensions, weight and cost of CM chokes applied in CM voltage compensators. Originality/value – In the paper, the new formulas that describe the placement of triangular carrier functions for commonly used multilevel inverters have been presented. In order to avoid accumulation of the estimation error, during determination of the CM voltage time integral, a dedicated, efficient method of roots approximation has been developed.

In the paper we have investigated the EMC aspects of the proposed modulation algorithm in the comparison with the conventional carrier-based SVPWM. Our results showed that the choice of this modulation causes that the conditions for the compensation, by means of zero common mode (CM) voltage filter, become more favorable then in a case of the conventional SVPWM. In spite of the fact that frequencies of gate pulses are the same in both modulations, the CM voltage frequency is doubled. The time durations of the CM voltage shelves decreases twice and consequently the time integral value of the CM voltage and the magnetizing current decrease as well. This results in reduction of the size, weight and cost of inductive components of filters in multilevel drives.
