The flow of electricity in our houses, as we are aware, is recharging extremely fast, from our houses, workstations, schools and all other industries that utilize electricity. The traditional power grids that were constructed to run at one speed are now struggling to meet the challenge of the new ones based on either wind or solar that produce energy in an uncontrolled manner. While the electric cars and smart devices bring new consumption challenges. All of which combined with aging infrastructure and unpredictable extreme weather, the electricity grid businesses require the capability to be able to observe power activity in real time.
This is where the Internet of Things (IoT) comes into existence. IoT refers to a collection of devices that collect, send and process data automatically. Simplifying this to power grids, these devices act as sensors that monitor variables such as voltage, current, equipment temperature and environmental conditions continuously.
With all of that equipment installed, grid operators can identify problems and get to them in a matter of time. Utilities no longer need to wait for individuals to call in with issues, now they can observe issues in real time and contact them, usually before anyone even realizes there was an issue.
How effective this will be is a function of how good the wireless connection is. It depends on how far the signal must travel, how much data is being transmitted, and how much data is available. LoRaWan, for instance, is excellent at pushing data over distances and requires a small amount of power, and this is excellent for monitoring distant sites such as rural substations or lines. The second instance is Zigbee, it functions optimally in a short range, hence it's most suited for busy areas such as suburbs, or a factory. It also creates a mesh network, and thus if one fails, the rest will be functioning.
And then we have Wi-fi that's very fast and can store more data, this is however largely used in the city where smart meters have to share data immediately. And finally, 5Gb, which is new but very quick, and this makes it a good competitor to real-time communications and quick decision-making for the power grid.
One of the easiest examples of how IoT is applied in real life would be a smart meter. This kind of meter monitors usage of electricity in real life and forwards that data directly to utility companies. But such meters do not just monitor usage, they monitor if there is any issue in the system, identify symptoms of energy theft and even assist in predicting when equipment failure would happen.
Another one is an Internet-connected sensor that goes a step further and covers the whole grid from substations to transmission lines. They monitor such things as transformer heat, unexpected vibration, or hazards like ice accumulation or tree encroachment on power cables.
Environmental sensors also play an important part by sensing air and weather. They enable utility providers to forecast storms and maximize the use of renewable energy by forecasting solar and wind power in advance.
It's also worth noting that IoT is not just about data gathering, it's also about responding to it. These systems enable predictive repair and intelligent consumption of energy. Utilities receive instant notifications so that they can react to it quickly, fixing them in minutes instead of hours. Not only reducing outages but also reduced repair expenses and improved reliability. With true usage reports, companies can optimize the way power is delivered, identify wastage points, and even assist consumers in saving energy, another added boost to overall sustainability efforts.
Let's look at grid stability that further gets a boost to this. For instance, if an unexpected surge in power consumption originates from an industry, or there is less cloud cover to reduce solar power, the IoT systems can instantly implement changes that level things out.
And of course, implementing all these new technologies comes with its own set of disadvantages. The more devices that are added to the mix, the larger the exposure to cyber-attacks. Thus, robust security such as (encryption, fire wall, and isolated network ) is a necessity to have.
Connectivity is also something to worry about. For instance, in rural terrain, poor cell signals are an issue. In the city, the issue could be one of interference caused by there being too many devices on the network fighting for signal. Battery-powered long-distance sensors also must be wary of power so that they don't go off-line for a long period of time without regular maintenance.
As increasingly more IoT devices are added to the grid, utilities will also have to consider how all of it gets along. Various systems will have to talk to one another, which means standardization is the way to go. Keeping devices up to date with the most current firmware will also be important to long term dependability and security.
There is also increasingly a demand for individuals familiar with installing, running, and servicing such systems. As technology develops further, professional training and education in a specific area will even be mandated.
In conclusion, IoT is revolutionizing the way we manage our power grid. And it's not only replacing equipment, but the ethos of energy. The way we generate it, transmit it, and utilize it. And sure, there are certainly some things to work out, but we can't ignore the value, increased reliability, efficiency, and sustainability it brings in making it an investment to make in the future.
