Recent advances of the signal processing techniques in future smart grids
Smart grid is a network of electric supply that manages power demand in reliable and economic manner by detecting and reacting to local changes in usage. The infrastructure comprises of smart meters, appliances, and resources with a combination of modern technologies like, control, power, instrumentation, and communication. In such a complex scenario, signal processing techniques are essential to understand, plan, design and operate the complex future smart electronic grids . In addition to this, signal processing has wide variety of applications and is becoming an important tool for electric power system analysis. This is due to the fact that measurements retrieved from numerous locations of the grid can be used for data analysis. These measurements can also be used for a variety of issues such as voltage control, power quality and reliability, power system and equipment diagnostics, power system control and protection, etc .
Smart grid challenges and signal processing based solutions -A Literature survey
International Journal of Engineering Trends and Technology, 2016
Smart grid is a power grid which allows bidirectional power flow along with information interchange between supplier and user. It promises power can be more efficiently and reliably generated, transmitted and consumed over conventional electricity systems. To establish the above grid system the conventional grid system should be upgraded with new technologies. This paper presented the techniques to meet the smart grid requirements and also spells the challenges while deploying the advancements. More over the increases of distributed generators (solar, wind etc.) need integration with smart grid for the purpose of managing peak load. In this article some of the smart grid challenges and the solutions in signal processing perspective are presented.

Smart signal processing for an evolving electric grid
EURASIP Journal on Advances in Signal Processing, 2015
Electric grids are interconnected complex systems consisting of generation, transmission, distribution, and active loads, recently called prosumers as they produce and consume electric energy. Additionally, these encompass a vast array of equipment such as machines, power transformers, capacitor banks, power electronic devices, motors, etc. that are continuously evolving in their demand characteristics. Given these conditions, signal processing is becoming an essential assessment tool to enable the engineer and researcher to understand, plan, design, and operate the complex and smart electronic grid of the future. This paper focuses on recent developments associated with signal processing applied to power system analysis in terms of characterization and diagnostics. The following techniques are reviewed and their characteristics and applications discussed: active power system monitoring, sparse representation of power system signal, real-time resampling, and time-frequency (i.e., wavelets) applied to power fluctuations.

This paper proposes a novel framework for an intelligent monitoring system that supervises the performance of the future power system. The increased complexity of the power system could endanger the reliability, voltage quality, operational security or resilience of the power system. A distributed structure for such a monitoring system is described and some of the advanced signal processing techniques or tools that could be used in such a monitoring system are given. Several examples for seeking the spatial locations and finding the underlying causes of disturbances are included.
Communications Technologies for Smart Grid Applications
IGI Global eBooks, 2018
Smart grid is a modern power grid infrastructure for improved efficiency, reliability, and safety, with smooth integration of renewable and alternative energy sources, through automated control and modern communications technologies. The smart grid offers several advantages over traditional power grids such as reduced operational costs and opening new markets to utility providers, direct communication with customer premises through advanced metering infrastructure, self-healing in case of power drops or outage, providing security against several types of attacks, and preserving power quality by increasing link quality. Typically, a heterogeneous set of networking technologies is found in the smart grid. In this chapter, smart grid communications technologies along with their advantages and disadvantages are explained. Moreover, research challenges and open research issues are provided.

Smart Grid is an advanced two way data and energy flow capable of self-healing, adaptive, resilient, and sustainable with prediction capability of possible fault. This article aimed to disclose Smart Grid communication in a logical way to facilitate the understanding of each component function. The study was focused on the improvement, advantages, common used design, and possible feature of Smart Grid communication components. The results of the study divide the Smart Grid communication application into two main category i.e. measurement equipment and network architecture. Measurement equipment consists of Advance Metering Infrastructure, Phasor Measurement Unit, Intelligent Electronic Devices, and Wide Area Measurement System. The network architecture is divided based on three hierarchies; local area network for 1 to 100 m with 100 kbps data rate, neighbour area network for 100 m to 10 km with 100 Mbps data rate, and wide area network for up to 100 km with 1 Gbps data rate.

Novel Approach based Smart Grid Involved in Energy Consumption using Signal Transmission
The objective of this deliverable is to explore several cases for smart grid in the ICT point of view and identify necessities and architectural consideration. There is a use case for demand response signal generation for scheming home appliances. Electricity service provider's operating system makes several of DR (Demand Response) signals that is generated by multiplication of individual CBL (Customer Baseline Load) in lieu of the customer's electricity usage patterns and dynamic pricing from power exchanges. And DR signals in the operating system are transmitted to the gateway in customer houses. DR signal pass to the consumer electronics and appliances. Power consumption of appliances varies depending on DR signal.

The fundamental way of operating the power grid has not changed for the past century. It has remained essentially the same, although the number of consumers and their needs have grown exponentially. Utilities across the world are trying to figure out how to bring the network into the 21st century and the digital computer age. This effort will make the power grid more intelligent; the latter is broadly referred to as the smart grid (SG). However, while modern technologies have transformed much of the economy, the electric industry and in particular the distribution grid has not yet embraced or implemented these technologies. This paper reviews works related to smart grid, presents the need for smart grid technologies by identifying its benefits along with different areas of its application for the realization of reliable and efficient grid structure. Proper utilization of these technologies could bring improvement to the operation of smart grids and possibly eliminate the challenges they encounter. SG makes use of information and communication technology (ICT) to take care of the reliability impact of the smart grid resources such as renewable energy, demand response, energy storage and electric transportation [1], . The SG must be connected to a secure two-way communication network with energy management tools which is essential for the aggregation of data coming from a very large number of sensors and actuators nodes. The communication network is the key enabler needed for the achievement of SG. Communications provides advanced control and monitoring, including supporting the involvement of generation, transmission, marketing and service provision to new concerned groups .
