“…In contrast to active and passive schemes, they do not decrease the power quality and have a smaller NDZ [1]. Communication-based systems employ data transmission between protected devices and can be based on supervisory control and data acquisition (SCADA), power line communication (PLC), or communication with a utility recloser unit [5], [7], [14], [15]. Main challenges of this type of ID schemes is their relatively high cost, complexity, and operation speed.…”

As smart grid applications, distributed generation, and microgrid technologies have become more widespread, new safety-related issues have arisen. Unintentional islanding is an example of a grid fault that may result in damage to electrical equipment and severe personal injuries. In this paper, an antiislanding system employing power line communication (PLC) and direct-sequence spread spectrum (DSSS) modulation implemented with software-defined radios for continuous signaling is tested in a laboratory test setup. A concept of a fault detection algorithm is evaluated. A DSSS sensitivity analysis is carried out to investigate system's performance against variation of a signalto-noise ratio, and define optimal DSSS settings. The results of the analysis are interpreted, and conclusions are drawn. A transformer bypassing scheme allowing to increase the fault detection speed and throughput is introduced and tested, and the conditions of applicability are described. As a result of the study, recommendations for the system development are presented.

Summary Arguably, the most important challenge nowadays in the energy industry is the utilization of intermittent renewable energy sources. On the one hand, renewable sources are the future in terms of sustainability. While on the other hand, several questions remain unanswered in connection with their day‐to‐day operation and system integration. Creating microgrids with local control of the distributed energy resources seems to offer solutions but there is a lack of practical experience. Especially in Europe, where a microgrid with islanding capability is connected to a widespread, synchronously operating grid, it is a complicated task, owing to the control methods. In this paper, the technical possibilities are presented, which are necessary to allow island mode operation of a microgrid. The case study discusses a “living lab” in which several energy generation technologies have been deployed thus it is a good representation of future renewable‐based microgrids. To support the island operation, numerical calculations and simulations are used to determine power and energy needs of necessary flexibility measures. Basis of the calculations is the year‐long data measured on‐site. Sizing and operation modes for energy storage and demand‐side resources and an architectural scheme are presented. Net present value for all technological options are compared to aid the selection of the best option. A sensitivity analysis is also performed to assess how potential change in various parameters of the economical calculation affect the results. It is shown that provision of uninterruptible power supply and thus island operation of the site can be provided within reasonable techno‐economical limits.

--Distributed generation (DG) has gained popularity in recent years due to the increasing requirement for renewable power sources. A problem that exists with DG systems is the islanding of DG units that creates safety issues for personnel as well as the potential for damage to utility infrastructure. Therefore, islanding detection methods are utilized to mitigate the risk of islanded operation of DG units. A new passive method of islanding detection based on the signature of the PWM voltage harmonics is proposed. The viability of the algorithm is investigated with the use of an analytical and time domain model of the inverter and further validated with experimental results. Furthermore, an extension of the detection scheme is proposed for use in multiinverter scenarios composed of adaptive frequency hopping to eliminate unwanted tripping.
