Overview of Smart Grid Technology

Electricity is considered one of the basic needs of people, especially today wherein people’s lives revolve around technology. Almost all things work with the use of different devices and equipment to make our lives easier and convenient. Nevertheless, we’re all informed that power outage and electrical disruption are inevitable, it can happen later, tomorrow or the next day, we never can tell. This simple power disruption can affect peoples’ lives at work or even at home. So, people keep on discovering and inventing varieties of smart electrical equipment and devices to address such electricity failure and power outage. 

The electrical grid is not only composed of one entity but multiple power generation companies and networks with the huge scale of operators and workforce to sustain the electric distribution throughout the community. However, due to the increase of power demand and shortfalls in power generation all over the world, developments were made to meet the needs of the community. Thus, ended up making a systematic method of distributing energy through the use of this so-called “Smart electrical grid”. 

Over the years, the electric power system is rapidly but continuously evolving and due to the increasing demand for modern society, a new wave of electrical grid was employed. It is called “Smart Electrical Grid” this grid is highly comprised of advanced and smart digital technology to control, monitor and analyze the supply of an electric chain. Through its advanced technology, it can reduce the workforce and can provide safe, efficient, quality and reliable electricity to all valued consumers and communities. Aside from that, this smart grid can also reduce energy costs and electricity waste. Additionally, the smart electrical grid technology can also detect and isolates power outages, so it can minimize the effects of power outages in the community before it becomes wide rage blackouts. Or if power outages happen, it can easily route the electricity to emergency services to ensure that the electricity will quickly resume. It is also a great way to address ageing energy assets and infrastructure that needs to be upgraded for better performance. Moreover, it’s also a big aid to resolve energy efficiency since it brings awareness to the consumers about the real connection of the proper electricity usage to the environment—where renewable resources can be found.

What is Smart Electrical Grid?

A smart electrical grid is a combination of electrical network and digital smart communication technology which provides two-way communication between the utility provider and the end-consumers. Just like a computer, this electrical grid comprises a new set of different operational equipment and energy measures which includes smart appliances, automation, controls, smart meters, microgrids and other energy-efficient resources. Aside from providing a connection between utility and consumers, it’s also made for electric power production, conditioning and controlling electricity distribution on the community. 

Moreover, the smart electrical grid provides electrical power from various and multiple distributed energy sources such as solar power systems, wind turbines and even vehicles with hybrid electric plug-ins.

With the use of this smart system, it is now easy for the power generation operators to determine the energy requirements of different zones including the availability of energy sources from each zone or area. This also increases the connection and coordination between the networks, suppliers and consumers through the use of digital automation that can also perform even in long-distance transmission and electrical distributions. 

So far, a smart grid has more than 9,200 power generating units with over 1 million MW capacity connected to more than 300,000 miles of transmission lines.

History of Smart Electrical Grid

During the late 20th century, electric power generation began commercializing in the industry and the local grids are eventually interconnected for some economic and reliability reasons. Due to the revolution of the light bulb and the said advancement of electric motor, the demands for the electric power generation increased. This leads to the rapid development of the power distribution system. In the beginning, small power utility companies can only provide power to the local industrial plants and other private communities while others generate their electrical power. But this did not end there, since they are seeking greater and efficient power distribution, utility companies decided to pool all of their resources and started sharing and exchanging transmission lines with other regions to form electrical networks which are called “grids”. 

The development rapidly increased as George Westinghouse introduced to the industry his hydroelectric power plant located in the Niagara falls. He was the first man to offer power over the long-distance regions by extending the range of his power plant positioning. As the power utility companies continued to expand, local grids also increased its connections to other grids and eventually formed the three national grids. The Western, Eastern and the Texas Interconnect were able to link themselves to form the so-called “national power grid”.

Through the 1951s to 1961s (post World War II), the technological improvements of the power grid system largely improved because of the computer controls, nuclear power and other technology developments. Whereas during the 1970s to 1990s, greater numbers of power stations were sprouting but in spite of this, there was still a shortage of electricity supply resulting in poor electrical power quality and blackouts, because of the highly increasing demand. 

Also, automatic meter reading was used for monitoring power loads from large customers during the 1981s, and finally modified and evolved it into the Advanced Metering Infrastructure in the year 1991s. Smart meters were also used together with the automatic meter to make communications flow continuously so the monitoring can be done in real-time. Also, during the early 1991s wide area networks’ monitoring and synchronizing were revolutionized after Bonneville Power Administration decided to expand its smart grid research.

The development of the electrical power system continues over the past few years to meet the 21st-century technology standards and demands. With the help of today’s technology, the power grid becomes a smart electrical grid now, which can record, analyze and react to data transmission. Thus, making the power system and resources management efficient and more cost-effective for the end-consumers. In today’s century, China, Brazil and India, were seen as pioneer countries of smart grid deployment.

Smart Electrical Grid Components

A smart electrical grid will never be called “smart” if it doesn’t have a wide range of modernized technologies. So these technologies should be implemented along with this electrical grid.

Smart Power Meters

These Smart power meters provide two-way communication between the electric power providers and the end-user consumers to detect device and equipment failures so they can easily deploy repair crews to the exact location or area. Additionally, this can also provide an automated data collection’s billings for the consumers.  

Smart Substation

This includes monitoring critical and non-critical operational data control such as power status, transformer status, power factor performance, security, breaker, etc.

Substations are being used to transform voltage at certain times in different locations and areas. Providing end-user consumers with reliable, efficient and safe electrical power. It is also responsible for splitting the path of the electricity flow into several directions. The reason why it needs high quality and large equipment including network protected relays, transformers, capacitor banks, circuit breakers, switch and other pieces of equipment to operate. 

Intelligent Appliances

Intelligent appliances can decide when to consume electrical energy through the customer’s pre-set preferences. This is done to reduce electrical peak loads so it can’t affect the consumer’s electricity generation costs. 

Integrated Communications

It is considered as the key to smart electrical grid technology. Smart Grid communication uses different types of methods and software like Supervisory Control and Data Acquisition (SCADA), Programmable Logic Controller (PLC), cellular, wireless and BPL to comply with the needs of the system, as fast as it can. 

Super Conducting Cables

Whereas, these cables are used to give long-distance power transmission as well as providing automated monitoring and analyzing tools to predict and detect faults and failures on the device based on the power outage history and real-time data weather forecast. 

Key Features of Smart Grid

  1. Smart – it can sense certain system overloads and rerouting the power grid to minimize potential blackouts or avoid potential power disruption in the areas. 
  2. Green – it’s another purpose is to maintain the green-life here on Earth while providing efficient power grid distribution. 
  3. Adaptable – it can virtually accept renewable energy from any sources like solar and wind, as well as integrating to other energy storage technologies. 
  4. Reliable Service – it offers two-way communication between the individual user and utility providers. So consumers can easily determine their energy consumption and other concerns. Also, it encourages every consumer to participate in grid operations to reduce the consumer’s electricity bills.
  5. Decentralizing Power Generation – A decentralized or distributed power grid allows the consumer to generate their onsite grid by guiding them with the proper methods.

A smart grid is an electrical grid, that is digitally enabled to procure & distribute information in order to improve the efficiency, reliability and sustainability of electrical devices. It involves the application of digital processing and communications to the power grid. A smart grid replaces analog mechanical meters with digital meters that record usage in real time. It improves the electronic control, metering, and monitoring.  It uses the smart meter, which is an electrical meter that records consumption of electricity and communicates that information for monitoring and billing purposes. These meters communicate continuously so that monitoring can be done real time.

One major benefit of the smart grid is its ability to enhance a utility’s capacity to connect with and empower its customers. A robust customer engagement platform is at the heart of that enhanced relationship, providing a multitude of ways to educate, entice, and excite customers. Today, consumers can take advantage of direct savings by better monitoring and controlling their energy usage. This will enable service providers to capitalize on new revenue and cost-saving opportunities.

Benefits of Using Smart grid Technology

The smart grid will make use of technologies that improve fault detection without the intervention of technicians. Thus there is more reliable supply of electricity, and reduced vulnerability to natural disasters or attack. Classic grids were designed for one-way flow of electricity. Smart grid technology enables distributed generation of energy flows & the systems can even control multiple energy flows from different sources. If a network generates more power than it is consuming, there can be a reverse flow, which can endanger safety and reliability.  However, a smart grid is designed to minimize these situations.  The overall effect is less redundancy in distribution lines, and greater utilization of energy flow, leading to lower power prices. Moreover customers can play an active role as both power consumer and power producer and can control their power consumption in a cost-optimized and environmentally responsible manner. When properly implemented, these technologies will increase efficiency in production, transport and consumption, improve reliability and economic operation, integrate renewable power into the grid, and increase economic efficiency through electricity markets and consumer participation.

Given how controversial smart meter rollouts have become of late, what are the optimum sites for smart grid initiatives?

Ideally, you’d look for something that’s self-contained and with a population that’s localized and small enough to keep the costs of comprehensive updates relatively low. If that sounds like a university, you’re on the same page as UCLA, whose Smart Grid Energy Research Center (SMERC) just got another boost in its goal to make the university’s sprawling campus a model smart grid paradise.

“UCLA is like a little city — Pasadena, Burbank and Glendale are not much bigger,” Rajit Gadh, the director of SMERC and an engineering professor who specializes in wireless smart-grid technology, said in a release. “With a city like UCLA, we can test our concepts very quickly, as well as conduct very interesting tests.”

SMERC is already funded by the Energy Department and the L.A. Department of Water and Power. This week, it announced that it had finalized a 10-year partnership with the Korea Institute of Energy Research, a government-supported think tank in South Korea, to swap ideas and research to build a baseline for an international smart grid.

As part of the plan, Gadh’s group is retrofitting buildings on the UCLA campus — starting with the engineering department, naturally — with metering and sensor systems. The project is aimed at moving past residential smart meters toward testing sensor networks for coordinating the usage of all electric devices. By testing at the full-building scale, Gadh and SMERC hope to iron out the bugs in networked smart grid systems.

The cornerstone is Gadh’s WINSmartGrid network platform. It’s being developed as an all-inclusive platform to wirelessly monitor and control appliances, environmental and HVAC systems and EVs. The whole thing is run through a web service that cross-indexes usage data with feeds from utilities on the price of power throughout the day. In theory, it’s a way to automatically balance a building’s electricity needs with a utility’s flexible pricing scheme.

San Diego Gas & Electric Co. (SDG&E) and Sudberry Properties have announced plans to incorporate breakthrough smart grid technology in the construction of Civita, the new master-planned development in Mission Valley, California. With a focus on sustainability and energy-efficiency, the “smart energy community“ will be home to vehicle charging stations, solar and fuel cell electricity, battery storage and energy management tools for residents.

“The Civita project is consistent with what we are trying to achieve here in San Diego,” said Mayor Jerry Sanders. “By integrating solar power, clean transportation and energy efficiency into the very foundations of our homes and businesses, we can help preserve the environment while strengthening our community overall.”

With plans to build nearly 5,000 homes and around a million square feet of office properties, apartment living, public parks, and a civic center over a once 230 acre gravel quarry, Civita could become one of the first communities in the nation to be “fully upgraded with smart grid technology and stand at the forefront of the broader transformation of the electric grid the community.” Civita aims to surpass current California energy efficiency standards by at least 15 percent by using energy star appliances, highly efficient residential lighting and onsite power sources, and by allowing some buildings and areas within community to operate independently of the grid.
