Why intelligent UPS technology is critical to network flexibility | Knowledge of the data center

A recent survey by OMDIA, an analytics and consulting firm, found that 90% of data center operators surveyed are likely to deploy UPS systems to interact with the network and support essential energy management initiatives within the next four years. . Adoption comes as rising energy demand and momentary imbalances common to renewable energy sources increasingly threaten to cause frequency variations and, if uncontrolled, disruptions. This is where the interaction of the network service comes into play.

An intelligent battery and uninterruptible power supply (UPS) system is designed to interact with and balance the grid during times of instability and unlock benefits such as cost savings, increased operational resilience, and even new revenue generation opportunities.

Read on to find out why these energy storage systems are critical for grid balancing.

The advantages of grid-interactive UPS technology

Backup batteries in a UPS spend much of their life unused. Intelligent UPS technology uses battery storage systems to store energy and release it instantly when needed, without hampering the UPS system’s ability to protect the load. Additionally, a grid-interactive UPS can be designed to provide fast enough response for dynamic frequency regulation.

Here’s how to choose the right UPS technology for your business goals.

Basics of grid balance

A grid-interactive UPS must be able to supply auxiliary services while maintaining sufficient battery autonomy to allow normal transfer to the generators in the event of a user failure.

When the external controller detects a change in the mains frequency, it commands the UPS to follow this request, adjusting to a specified power set point by charging or discharging the batteries within their operating limits. The UPS controls the input power to achieve certain goals or services, operating in a variety of different modes.

Revenue and balancing benefits

A grid-interactive UPS can enable businesses and home energy users to commercialize the energy they store and reduce overall energy costs by using balancing services. This type of management ensures that the energy supply matches the actual demand, reinforcing the stability of the grid and enabling the generation of revenue and energy savings.

In rapid rate response service programs, UPS battery storage systems are used to store energy and release it instantly. Alternatively, demand management, also known as “peak shaving”, is a balancing approach that reduces grid dependency in times of energy shortage or high energy costs. Demand handling services are offered through programs where companies receive regular financial payment based on the contract size for these services.

Data center organizations that offer grid balancing services receive additional “power” payments based on how quickly they react to grid frequency changes and the reduction in energy consumption achieved.

Network Support Challenges and Solutions

With such new technology, some operators worry about making changes to the UPS technologies their customers rely on for the protection of their critical systems, as well as whether this grid-supporting technology will cause batteries to age or degrade faster. .

UPS features such as Vertiv’s Dynamic Grid Support not only enable grid flexibility, power stability and demand management, but protect batteries from deterioration with UPS control systems that can fail or fail when operating conditions are out of specification or increase risk. In addition, major UPS systems are designed with optimization, advanced diagnostics and lithium-ion battery storage functions to control major aging factors.

As the industry moves to stabilize the grid and withdraws from traditional energy sources, few will be able to ignore the benefits of a grid-interactive UPS. Download our white paper to learn more about these benefits and how to use grid-interactive UPS technology to maximize revenue.
