Electrifying the Future: Advancements and Difficulties in Electrical Distribution and Transmission

04 Sep 2024

Introduction:

The electrical industry plays a pivotal role in supplying energy to our contemporary society, and at its core are the procedures of transmission and distribution. These two fundamental components guarantee the safe and efficient transmission of electricity generated at power plants to households, businesses, and other consumers.

Transmission refers to the movement of electricity from power plants to substations. High-voltage power lines, which are supported by tall transmission towers, are used to transmit electricity over extensive distances with minimal loss of energy. This is crucial for supplying electricity to areas that may be far from the power generation site.

On the other hand, local delivery of electricity from substations to individual consumers is what distribution involves. In this process, low-voltage power lines are used as the electricity passes through transformers to reduce the voltage to levels suitable for use in homes and businesses. Equipment such as poles, cables, and transformers is included in the distribution network to ensure the safe and reliable transmission of electricity to end consumers.

The transmission and distribution of electricity are essential for maintaining a stable and reliable electrical grid. Without proper infrastructure and maintenance, power outages may occur, affecting businesses, homes, and overall economic productivity.

With technological advances and a growing demand for renewable energy sources, the electrical industry is continuing to evolve. Smart grids are being developed with digital technologies and communication systems in order to improve efficiency, monitor power usage, and integrate renewable energy sources into the grid.

As we strive towards a more sustainable future, the significance of transmission and distribution within the electrical industry cannot be overstated. These processes play a vital role in powering our world by ensuring reliable and efficient delivery of electricity to consumers while minimising the environmental impact of energy production.

What Is the Transmission and Distribution of Electricity?

Although there are many sources of energy, have you ever wondered how energy generated from wind, sun, water, or other sources reaches you? This process is interesting and complex. Let’s discuss and learn what the transmission and distribution of electricity are and how they work.

What exactly is called the transmission and distribution of electricity?

The transmission and distribution of electricity pertains to the various stages of transferring electricity from the source to the residence or establishment via poles and wires. The transmission and distribution of electricity is not the same thing. The primary difference between the two is the voltage at which electricity moves through each stage.

After electricity is generated at the source, regardless of the source, a network of electrical wires transports it to our homes and businesses. These lines can be found overhead or in the ground, and when combined, they form the electrical grid.

Let's understand this a little more closely and in detail:

Transmission: Transmission is the "interstate highway" for the distribution of electricity. It refers to the portion of electricity distribution that transports bulk electricity over long distances from power generation sites to substations closer to areas demanding that electricity. Transmission lines consist of large, tall poles and towers that carry numerous wires over extended distances. Transmission lines carry large amounts of electricity at high voltage levels. These levels are too high to be delivered directly to a home or business.

Distribution: Transmission is the interstate highway of the grid, and distribution is the small street in the city. The final phase of transferring electricity from generation to the consumer is known as distribution. The voltage of electricity transmitted through transmission lines is reduced by transformers before being transmitted to distribution lines. Electricity traverses the distribution system at a voltage level that can be delivered directly to a residence or establishment. Distribution lines refer to the lines that are visible on streets leading to your residence or establishment, among other things.

To put it in simple terms, transmission of electricity occurs at a much higher voltage than distribution. Transmission lines are the huge power towers and lines that you see in the sky, while distribution lines are the ones that go directly to homes and businesses.

The Impact of Forthcoming Digital Technologies on the Transmission and Distribution Industry

Over the past 100 years, the transmission and distribution (T&D) of electricity have evolved step by step. The current use of digital technologies for construction, maintenance, and monitoring offers significant potential for the establishment of cost-effective, efficient, and more reliable T&D lines. We are currently undergoing a significant transformation in the digitalization of energy systems, owing to the emergence of diverse technologies such as block-chain, artificial intelligence (AI), IoT, and big data analytics, among others. The modernization initiatives undertaken by the T&D industry have been influenced by the advancements in digital technologies over the past two decades. These include the incorporation of intelligent electronic devices (IEDs) and internet connections that facilitate interoperability and communication among connected devices.

The Major Challenges That will Going to Face

• Aging Infrastructure: In many countries, the existing electric power distribution system relies on an out-dated transmission and distribution infrastructure. This infrastructure reflects technological advancements dating back to the 1950s and is currently experiencing challenges in meeting the increasing demand of today. Approximately 40% to 45% of T&D assets are currently in need of replacement or will soon require replacement, necessitating significant investments on both the transmission and distribution fronts.

• Monitoring and Inspection: Overhead transmission and distribution lines are among the most extensively used assets of power utilities. These transmission and distribution lines can span several miles, even via remote areas, which makes monitoring and inspection activity very challenging for utilities. In the past, inspection teams visited these T&D line locations once or twice a year to detect faults or for scheduled inspections. Despite the significance of this task from the utility's perspective, it has the potential to become a time-consuming and costly undertaking.

• Grid Stability: The proliferation of renewable energy and remote power generation has led to several challenges for power grids, including grid stability. The intermittent nature of renewable energy, such as wind power, makes it more difficult for grid operators to provide a steady flow of electricity to consumers. This has increased the load on the grid infrastructure and brought the grid closer to its stability limit.

Digital Technologies

Newer digital technologies have the potential to alleviate the difficulties encountered by the T&D industries. These technologies have been embraced by various utilities worldwide and are currently used in diverse applications. The following are some examples of digital technologies that can address the challenges faced by the T&D sector.

• Artificial Intelligence: Artificial intelligence-based systems have the potential to enhance the efficacy of power grids by optimizing their utilization by utilizing substantial quantities of weather-related data. This could lead to a better use of existing lines, according to weather conditions. Artificial intelligence has the potential to enhance safety, reliability, and efficiency within power grid systems.

• Machine Learning: A machine learning algorithm can assist in predicting the failure model of a distribution feeder element. It can use data inputs such as power quality data, maintenance, and inspection work to analyse and predict the failure. Machine learning has the potential to aid in the development of novel intelligent BIM (building information modelling) models. Digital technologies using machine learning to semi-automate the process of creating intelligent BIMs are being experimented with.
