Nowadays, the expansion of renewable energies (the wind, solar, ocean wave, fuelcell-some of them are natively DC) in power system as a potential solution for the environmental protection and lack of energy when the traditional energies are going to be exhausted. Besides, the development of fullness DC as storage technologies (batteries and ultra-capacitors), and DC loads (Data centers, electronic based office, home appliances, plug-in electric vehicles, variable speed drives and DC electric arc furnaces) are significantly increased. Furthermore, DC distribution leads to advantages than AC distribution such as reduced losses, safety, abatement of electromagnetic fields, and power quality improvement was shown in [2]. Moreover, in recent years, there are a lot of DG connected directly with DC grid and continuously connected to AC to created hybrid grid to increased the power efficiency. However, there are many problems in DC grid with DG and one of the most important is islanding detection, the same with AC grid. There are many papers about IDM for AC grid but until now, the investigation about IDM for DC grid is missing. Therefore, this paper will concern about the existing IDM papers such as [3]-[6], discussion about advantages and disadvantages of IDMs and proposed some potential solutions applied to DC grid. This paper will give us a view clearly, the trend, and difficulties in research about islanding detection methods in DC networks.

Energy flexibility is becoming more significant part of future power systems. Buildings can be a massive source of flexibility to face the challenges associated with the Smart Grid. Specially, a collection of buildings or a neighborhood can offer better flexibility by managing their energy profile. There are a number of standard frameworks developed to provide support for the design of different smart grid use cases and to facilitate the interoperations among different actors in the smart grid context. But there is a lack of a comprehensive architecture framework which specifies the role of smart neighborhood. This paper reviews the existing research frameworks of Smart Grids and how to incorporate future intelligent neighborhood energy management systems into these frameworks. The analysis identifies gaps in the existing frameworks and proposes a modular interoperability framework focusing on the smart neighborhood aspect.

Aluminium is widely used as conductor material for power cables, but corrosion taking place under specific circumstances can have impact on its reliability. Aluminium corrosion under the influence of an alternating current was studied experimentally. Submerged cable segments with inflicted damage exposing the conductors resulted in a continuous corrosion of the conductor material. Effects of temperature and applied voltage were studied by observing corrosion of an aluminium wire. These parameters strongly affect the corrosion rate. Comparison with copper showed that aluminium is far more susceptible to corrosion. The impact of corrosion on the reliability of the cables is discussed.

The control of modern electrical power systems is, in some respects, limited by traditional analogue control methods. It is recognised that digital control can offer significant advantages in enhancing a power system's closed-loop performance and improve control implementation over traditional analogue methods. In particular, an electrical power system can exhibit optimum performance throughout its operating range and even enhance its operating range through the use of dynamic digital control-coefficients. This paper seeks to describe the process by which a system under continuous-time control can be converted into one which operates with digital control. The aim is to provide an introduction to digital control, based on a design process using the open-loop frequency response of a system. Several problems encountered when designing a digital controller are highlighted; in particular, the effect of the sampling time on the performance of the system. The system performance under digital control is compared to its analogue equivalent, and suggestions are made to minimise the difference between the performances of the two types of implementations.

This paper presents an investigation into the potential benefits of interconnecting adjacent 33 kV demand groups in the GB distribution network by presentation of two case studies. Results presented are, firstly, a comparison of load profiles of adjacent groups and, secondly, following application of a series of credible future scenarios, the potential reduction in loss of load and generation curtailment achievable from interconnection and the proportion of time for which interconnection would be utilised. It was found that there is significant dissimilarity between load profiles of the adjacent groups analysed and interconnection could be valuable for the future distribution system. The value of interconnection could be increased with the use of storage, though more analysis is needed to quantify the economic viability of this.

Numerous changes in electrical grid schemes, like the inclusion of renewable energy, the rise of non-linear loads and the emergence of electric vehicle charging, increases variable power quality conditions of the grid. In this dynamic scenario where energy could flow in both directions and the waveforms could be highly distorted, accuracy becomes a crucial factor for the correct measurement of electrical energy and power values. Errors in the assessment of these values have significant ramifications for revenue, billing and/or control. This non-ideal power quality scenario produces an error in electricity meters, that is not yet well known since there is no standardised procedure to calibrate meters under typical or emerging distorted waveform conditions. Current standards relevant for revenue energy meters like EN 50470-3:2006 allows measurements error up to ±2.5% while local regulations could be even more permissive. In order to establish an electricity fair trade market and meet expectations from consumers and utilities, electricity meters should arguably comply with higher accuracy standards. In this paper, the pertinence and possible impact of including tests under distorted waveform conditions, as well as new accuracy requirements on standards applicable to electricity meters for billing purposes will be discussed.

Electricity access is a key enabling factor for human development, yet over 1.2 billion people have no connection. Minigrids, grid extension and standalone systems are the standard approaches to electrification, but each have significant limitations, including cost of energy, speed of deployment and lack of flexible upgrade paths. Interconnection of minigrids and Solar Home Systems (SHS) to allow import and export of energy can address many of these issues. Increased diversity can reduce the impacts of variable renewable energy resources and incremental investment over time can facilitate a flexible, bottom up route to universal electrification. This paper discusses the issues surrounding the existing approaches to electrification in developing countries and outlines the opportunities for minigrid interconnection as a method to accelerate electricity access in a sustainable, cost effective and future-proof manner.

Alongside the ongoing energy system transition towards sustainability new challenges for low voltage grids arise. New technologies connected to those subordinate grids are less predictable, especially decentralized solar plants. Larger loads and a possible reversed power flow lead to increasingly unknown states and can evoke violations of power quality. This paper presents a method to determine an optimized meter placement in low voltage grids using an asymmetric state estimation in order to achieve a cost-efficient monitoring. First, the utilized state estimation method is introduced as well as the usage and parameterization of pseudo measurement values are discussed. Furthermore, a new approach for an optimized meter placement is presented and simulation results for exemplary grids and corresponding power flow data are shown. Subsequent discussions focus on the quality of results subject to the amount as well as the specific positioning of meters placed.

The paper presents a few issues generated in low voltage distribution grids at the end user's level, by power system harmonics. The introductory section presents shortly harmonics sources, their analysis, effects and measurement methods, appealing mainly to the limits depicted in the specific standards. The following section presents two case studies of power electronics equipment drawing high distorted currents and having as consequence a high harmonic content. The first one represents a residential equipment supplied by a switch mode power supply, analyzed in laboratory conditions. The second, a variable speed drive, has been analyzed in an industrial environment, i.e. in real conditions. As a conclusion, harmonic measurements and analysis make possible the choice or the design of retrofitting mitigation countermeasures, capable to alleviate harmonics effects.
