TL;DR: The essentials of the progressive smart grid paradigm and integration of different communications technologies for the legacy power system are provided and foreseeable issues and challenges in designing communications networks for the smart grid system are rigorously deliberated.
Abstract: The present electric power system structure has lasted for decades; it is still partially proprietary, energy-inefficient, physically and virtually (or cyber) insecure, as well as prone to power transmission congestion and consequent failures. Recent efforts in building a smart grid system have focused on addressing the problems of global warming effects, rising energy-hungry demands, and risks of peak loads. One of the major goals of the new system is to effectively regulate energy usage by utilizing the backbone of the prospectively deployed Automatic Meter Reading (AMR), Advanced Meter Infrastructure (AMI), and Demand Response (DR) programs via the advanced distribution automation and dynamic pricing models. The function of the power grid is no longer a system that only supplies energy to end users, but also allows consumers to contribute their clean energy back to the grid in the future. In the meantime, communications networks in the electric power infrastructure enact critical roles. Intelligent automation proposed in smart grid projects include the Supervisory Control And Data Acquisition/Energy Management Systems (SCADA/EMS) and Phasor Management Units (PMU) in transmission networks, as well as the AMR/AMI associated with field/neighborhood area networks (FAN/NAN) and home area networks (HAN) at the distribution and end-use levels. This article provides an overview of the essentials of the progressive smart grid paradigm and integration of different communications technologies for the legacy power system. Additionally, foreseeable issues and challenges in designing communications networks for the smart grid system are also rigorously deliberated in this paper.

TL;DR: The work presented here proposes the principal characteristics for an effective integration of the Internet of Things in smart grid, and the application of IoT in smartgrid is emphasized.
Abstract: Advances in the areas of embedded systems, computing, and networking are leading to an infrastructure composed of millions of heterogeneous devices. These devices will not simply convey information but process it in transit, connect peer to peer, and form advanced collaborations. This “Internet of Things (IoT)” infrastructure will be strongly integrated with the environment. This paper focuses on researching on the architecture and key technology of Internet of Things. Moreover, the applications of Internet of Things are interpreted in this paper. Especially, the application of IoT in smart grid is emphasized. The work presented here proposes the principal characteristics for an effective integration of the Internet of Things in smart grid.

TL;DR: The main goal of this work is to present the specialist and nonspecialist review of the most important ESSurrently available on the market.
Abstract: With the recent advances in the field of applications which require a certain power level over a short period of timeand with the air-quality constraints which have become more stringent in the last few decades, the energy storagesystems (ESSs) have come to play a crucial role for the electric grid. Various aspects such as the historical evolutionof ESSs, technical characteristics, and applications for the ESSs are thoroughly addressed. Special emphasis is given tothe interaction between the smart grid (SG) and microcrogrids applications, on the one hand, and the ESSs, on the otherhand. Thus, the main goal of this work is to present the specialist and nonspecialist review of the most important ESSscurrently available on the market.

TL;DR: Wang et al. as mentioned in this paper proposed a privacy-preserving and efficient data aggregation scheme, which divides users into different groups, and each group has a private blockchain to record its members' data.
Abstract: Intelligence is one of the most important aspects in the development of our future communities. Ranging from smart home to smart building to smart city, all these smart infrastructures must be supported by intelligent power supply. Smart grid is proposed to solve all challenges of future electricity supply. In smart grid, in order to realize optimal scheduling, an SM is installed at each home to collect the near-real-time electricity consumption data, which can be used by the utilities to offer better smart home services. However, the near-real-time data may disclose a user's private information. An adversary may track the application usage patterns by analyzing the user's electricity consumption profile. In this article, we propose a privacy-preserving and efficient data aggregation scheme. We divide users into different groups, and each group has a private blockchain to record its members' data. To preserve the inner privacy within a group, we use pseudonyms to hide users' identities, and each user may create multiple pseudonyms and associate his/ her data with different pseudonyms. In addition, the bloom filter is adopted for fast authentication. The analysis shows that the proposed scheme can meet the security requirements and achieve better performance than other popular methods.
