Reactive power is an invisible but costly problem for many companies and municipal utilities. It occurs when electrical devices draw energy from the grid but do not convert all of it into usable power. Instead, some of the electricity flows back into the grid as reactive power. Although this energy is not directly consumed, it leads to grid overloads and increased electricity costs.

In an energy system designed for efficiency and stability, uncompensated reactive power can have a significant impact. On the one hand, it leads to grid instability, which under certain conditions can even cause voltage fluctuations or outages. On the other hand, the increased energy flow unnecessarily raises operating costs—an ever-growing financial problem for many energy suppliers and municipal utilities, which also burdens end customers in the long term.

In addition, reactive current compensation systems are very large, expensive, and there is no space for them in cities and urban areas. And even if there were, they would still cause noise.

The costs of reactive power

Inadequately compensated reactive power causes additional costs for energy suppliers. These costs arise because grid operators charge higher fees for transporting reactive power or because inefficiently operated devices draw more power from the grid than is actually needed. Energy suppliers usually pass these additional costs on to their customers. With rising energy prices and growing demands on grid stability, it is therefore becoming increasingly important to efficiently compensate for reactive power and thus minimize costs.

Digital solutions for reactive power compensation

Digital technologies now make it possible to monitor and control reactive power problems more accurately. With the help of intelligent energy management systems and digital platforms, grid operators can detect reactive power in real time and compensate for it automatically. These systems work with sensor data and advanced algorithms that intervene specifically as soon as the reactive power load increases.

The advantage of digital solutions lies in automation: instead of manual intervention, the system takes over the control of systems and devices to precisely regulate reactive power. This optimizes grid operation and greatly reduces losses due to reactive power. In addition, these systems can be flexibly adapted to the existing infrastructure and linked to a wide range of devices, making them suitable for a wide variety of applications.

Challenges and considerations

Although digital solutions offer a promising opportunity, the implementation of such systems is not without challenges. One of the biggest hurdles is integration into existing network and company structures. Often, outdated systems are in use that are not immediately compatible with modern digital platforms. Another issue is the processing of the large amounts of data generated by real-time monitoring. The systems must be able to process this data efficiently and make the right control decisions based on it.

Digital solution with the VGT platform

The VGT platform offers a comprehensive and scalable solution for reactive power compensation. It enables reactive power to be monitored and compensated in real time, which not only increases grid stability but also leads to significant cost savings. Thanks to its flexible integration into existing systems and the use of intelligent algorithms, the platform offers a future-proof solution for municipal utilities and energy suppliers.
