Distributed Energy and Temporary Power

In the age of small to medium-sized renewable energy plants that utilize solar, wind, or hybrid models for power generation, the demand for high-quality transformers is growing rapidly. At the same time, the rise of AI models and the rapid expansion of large-scale data centers have created a surge in demand for temporary power systems that support critical infrastructure.

Transformers are central to both distributed and temporary power solutions, ensuring safe, reliable, and efficient electricity delivery. However, these applications come with specific technical challenges and customer needs. We will explore these challenges and highlight how sustainable, adaptable transformer solutions—like those from Daelim—are addressing them.

Understanding the Market Needs

Distributed Energy Applications

The distributed energy systems DERs in simple words are off grid power systems that utilize energy resources like solar energy, wind turbines, batteries storage, and small scale generators to generate the required electricity. As these systems are mostly off grid power systems and they are utilized in small remote areas, these systems are usually installed near the point of use.

However this is changing, a lot of industrial units specially data centers and AI models and some residential setups are setting up their own distributed energy systems to meet their electricity needs. With increasing demand for these distributed energy solutions, there are some unique requirements that transformers need to fulfill to deliver safe and reliable electricity.

Those unique requirements includes

• Transformer compatibility with the variable energy input like from solar, wind, batteries, and diesel or CNG/LPG power generators.
• Transformer should be compatible with handling bidirectional power flow, for example power flow from batteries to transformer and from transformer to batteries. 
• Compact yet powerful design to meet the needs of indoor or compact space installations.
• Transformer design should also consider mobility as they need to be transported to remote areas.
• It should offer high reliability with minimum need of maintenance for uninterrupted supply and minimum running cost.

Temporary Power Applications

Temporary power systems are crucial for all those applications that need electricity temporarily. These are also considered reliable solutions in case of any emergency like natural disasters recovery site or certain military installations. 

Some common applications of temporary power systems include:

• Construction sites
• Mobile facilities and mobile power system
• Emergency response and disaster recovery
• Military bases and field installations

In such cases, there are some certain requirements led by the application and client that the transformer needs to fulfill.

• Transformer should be designed for fast deployment with an easy setup procedure.
• Entire setup should have mobile friendly design and should be rugged enough for off road transportation.
• Transformer enclosure and all its parts should have weather resistance capabilities with an overall compact design.
• It should be able to satisfy all international standards and ensure safety, reliability, and high efficiency in all types of transient use scenarios.

However in the age of AI models and data centers, a new problem has arrived and that is with new more powerful AI models and every growing data center puts a strain on existing electricity generation and distribution systems that it cannot support. This can be compensated with distributed energy resources but even they cannot deliver reliability in certain cases. 

In such scenarios temporary power applications offer a reliable solution till upgradation of national grid stations. To deliver a reliable, safe, and efficient temporary energy solution, you need a power source and a specially designed transformer that can ensure reliability and safety of the system and load attached to the system.

Key Challenges in Transformer Applications

With the comprehensive understanding of the market needs, the following is the set of key challenges that any electrical transformer manufacturing company will face during design and development of a specific electrical transformer that meets the needs of distributed energy and temporary power solutions.

Challenges in Transformer Design for Distributed Energy

Variable Load Condition

Electricity producing capacity of distributed energy resources like solar panels and wind turbines fluctuate rapidly. Transformer must be designed to deliver smooth output for fluctuating input.

Smart Grid Integration

Transformer designed for distributed energy systems should have features for integration with smart grid systems for grid automation and remote monitoring of systems.

Space and Accessibility

Some distributed energy resources have space constraints requiring a compact design transformer for easy transportation, installation, and maintenance.

Grid Compliance

Transformer must be designed to meet the evolving standard of distributed energy resources integration. It must be compatible with inverter based systems.

Challenges in Transformer Design for Temporary Power

Mobility and Handling

As temporary power systems are frequently moved between locations as needed, the transformer must be designed keeping in view the mobility and handling of the system.

Environmental Exposure

As temporary power systems are always placed in open fields as and when needed, the transformer enclosure should be designed in consideration with related NEMA and IP ratings.

Short Lead Time

In certain cases, temporary energy solutions are needed on an urgent basis, so the system and transformer should be designed to offer the shortest lead time possible.

System Compatibility

One single temporary power solution supports various voltage and frequency combinations for different generators and loads. So, systems need a transformer that can handle a wide range of voltage and frequencies.
