The Dutch power grid: challenges and solutions for your business

The energy transition brings challenges to the power grid. Solar panels, wind turbines and electric cars are straining the grid, which can lead to failures and outages with potentially major consequences for your business.

Do you recognise these challenges?

  • Reducing energy consumption and CO2 emissions: Want to reduce your carbon footprint and cut costs?
  • Increasing grid capacity: Do you need more capacity without having to modify your current installation?
  • Troubleshooting: Are you suffering from unexplained breakdowns and outages?
  • Insight into condition and consumption: Want to better understand the health and performance of your electrical system?

Common grid failures

The Dutch power grid can experience different types of outages, which can be roughly divided into two categories:

Mains power failures

  • Short breaks: Momentary power supply failure.
  • Total mains power failure: Complete failure of the power supply for an extended period of time.
  • Frequency fluctuations: Fluctuations in the frequency of alternating current (normally 50 Hz in the Netherlands).
  • Voltage fluctuations: Fluctuations in mains voltage (normally 230V in the Netherlands).
  • Harmonics: Distortions of the sinusoidal waveform of alternating current.

Load disturbances

  • Fluctuations in load: Changes in the amount of power consumed by appliances.
  • Unbalanced loads: Uneven load distribution across the three phases of the power grid.
  • Overload: Excessive power consumption, exceeding power grid capacity.
  • Peak currents: Short-lived, very high current spikes when devices are switched on.
  • Short circuit: Direct connection between phase and neutral, creating a very high current.

A good power conditioning system (PCS) is essential to protect your electrical equipment from these disturbances. The PCS must be able to detect and correct all these disturbances so that it can always provide high-quality power to your equipment, regardless of grid conditions.

What can we do for you?

Power quality problems can significantly damage your business. Extensive research has shown that voltage dips represent the largest cost, followed by harmonic problems. Although flicker problems are more common, their financial impact is usually less severe than that of large voltage dips.

Controlling your grid quality effectively often requires a multi-faceted approach. For this, Electroproject offers you a wide range of solutions from the renowned brand Piller. These solutions are specifically designed to address today's energy challenges, with the guarantee of availability, flexibility and continuity to minimise the impact of grid disturbances.

Piller Static and Dynamic UPS systems

To ensure optimum grid quality and protect your business processes from power outages and voltage dips, implementing an Uninterruptible Power Supply (UPS) system can be a worthwhile investment. There are two main types of UPS systems available: static UPS systems and dynamic UPS systems. Both static and dynamic UPS systems can be assembled from different configurations, depending on the desired functionality.

UPS System

Static UPS systems

A static UPS system feeds the load through a static IGBT inverter. Energy storage for the inverter can consist of various configurations, such as a battery, flywheel, supported battery container or diesel generator. This allows bridging times from 5-30 seconds to several hours.

Dynamic UPS systems

A dynamic UPS system, also called Rotary UPS, RUPS or DRUPS, feeds the load directly through a rotating synchronous motor/generator set. The power supply for this set can consist of an IGBT inverter combined with batteries or large-capacity flywheels (up to 60MJ). A diesel backup (DRUPS) can be achieved through a direct mechanical shaft coupling on the motor/generator set.

Why use a Piller UPS with flywheel

A Piller static flywheel UPS stores its kinetic energy in a rotating mass instead of batteries to provide backup power in case of power outages or major power failures, without interrupting the load.

A Piller UPS with flywheel offers several key advantages:

  • Cost savings: 40% lower total cost of ownership (TCO).
  • Sustainability: 98% energy efficiency and significantly reduced CO2 emissions.
  • Reliability: 12x less likely to fail than traditional battery systems.
  • Easy installation: Compact installation and quick commissioning.
