The Evolving Landscape of Power Grids
The power grid, much like oxygen, is essential to modern life, yet it often goes unnoticed until problems arise. Today, aging grid infrastructure is taking a beating from severe weather events around the world, resulting in power outages that threaten health, safety, and economic activity. Simultaneously, a number of other factors are putting pressure on century-old grids.
The way energy is produced is rapidly changing, with more wind and solar power and less coal and fossil fuel. This shift requires new processes and ways of managing the increasingly decentralized energy landscape. The “who” is also shifting, with energy now produced not only by major energy companies but also by a plethora of new competitors and prosumers – consumers who produce energy.
As the natural world changes fast, the technological world is advancing at a gallop. Cloud-connected artificial intelligence (AI) technologies like machine learning, data analytics, and the Internet of Things (IoT) are driving the advancement of smart grids capable of managing far more complex power generation and distribution. These technologies herald significant opportunity for those in the complex energy ecosystem who are able to harness them.
Prosumers and the Rise of Decentralized Energy
A prosumer is a portmanteau word combining “producer” and “consumer.” Energy prosumers typically remain connected to the central grid, but they are also capable of producing and even storing energy, often with photovoltaic solar panels and electric vehicle (EV) batteries. Depending on the amount of power generated, this energy can either be used to offset monthly bills or be sold back as surplus to utility companies or other energy distribution services.
This model may be applied to both residential and commercial prosumers, with a growing number of businesses plugging their solar panels and EV fleets into the grid. As the number of prosumers increases, the energy landscape is becoming more decentralized, challenging the traditional centralized model of power generation and distribution.
Understanding Smart Grids
A smart grid is a network that integrates energy distribution and digital communication technology in a two-way flow of electricity and data. This enables utility companies to optimize the generation, transmission, and distribution of electricity, and it also allows consumers to benefit from the insights that all that data is telling – helping them to better understand the energy they use and even the energy they produce and store through things like solar panels and EV batteries.
The main difference between traditional power systems and smart grids lies in the ability to exchange information in both directions across the network, from utility companies to consumers and vice versa. Some of the top features that differentiate smart grids include:
-
Artificial Intelligence: AI is the driving intelligent agent behind smart grids, evaluating the environment and taking actions to maximize a given goal. AI is fundamental to the integration of renewable energy, the stabilization of energy networks, and the reduction of financial risks associated with instability in the infrastructure.
-
Renewable Energy Integration: The self-learning adaptability and calculation capabilities of AI have significant potential to address the intermittent nature of renewable energy sources. An imbalance in peaks of production and consumption, often represented through the “duck curve,” can make these sources of energy difficult to control. The use of AI in smart grids will help address this challenge by rebalancing inequity between production and consumption loads.
-
Transparency and Competitiveness: Smart grid technologies help to make utility sector activities more transparent and competitive. This can lead to better customer engagement and satisfaction, as well as more efficient energy management.
Improving Customer Satisfaction with Smart Grids
Recent surveys from the UK and US show less-than-great customer attitudes toward utility companies. With the rise in energy suppliers and prosumers, utility companies will need to leverage smart solutions to help nurture better customer engagement and satisfaction.
One example of the potential benefits of smart grids for customers and the environment is a pilot project by a UK distribution system operator to use smart meter data to help consumers improve energy management, optimize network loads, and reduce carbon emissions. The trial could save customers millions of pounds and potentially reduce millions of tons of greenhouse gas emissions from the UK’s annual carbon footprint.
From the point of view of both customers and utility companies alike, it’s not simply the ability of these technologies to gather and manage large and disparate amounts of Big Data that matters – it’s the ability to leverage and understand all that data and use it to optimize power usage and inform operations. Big Data is key to helping utility companies and consumers alike make more informed decisions about energy generation, distribution, and consumption.
Overcoming Challenges in the Transition to Smart Grids
There is no question that the future of energy is moving toward more decentralized, flexible, and sustainable power provision. However, the energy industry is a global industry that is over a century old and often must rely upon infrastructures from nearly that long ago to serve billions of people and their rapidly changing demands.
Other challenges include:
– Complex regulatory changes
– The rise of prosumers and new startups emerging in deregulated regions
Like any journey of business and digital transformation, the move to smarter grid management starts with a few cautious steps before breaking into a run. Utility sector technologies are undoubtedly powering and enabling the evolution of this sector. However, for meaningful change to occur, utility companies will need to establish strong communication, customer engagement, and change management plans.
The Path Forward
The first step on the journey is to communicate with team leaders and subject specialists across the business to break down silo walls and find the wealth of information often hidden within. Then, look at how you can implement smart technologies to drive your business forward and transform the most important facets of your business to support the energy transition.
By embracing the power of sensor-enabled smart grids, utility companies and energy providers can optimize energy generation, distribution, and consumption, ultimately leading to a more efficient, sustainable, and customer-centric power ecosystem. As the world continues to evolve, the adoption of these innovative technologies will be crucial in meeting the growing energy demands of the future.
