Why power quality matters

The quality of electrical power is crucial to business. As the advance Technologies of electrical tools and machinery are more sensitive to network disturbances (eg, voltage sags), leading to costly downtimes and production losses. Proactive steps are needed to maintain productivity and revenue.
Unoptimized power supplies can cause harmonics, unbalance, and low power factor. This can lead to high bills, overloading, and aging of electrical infrastructure, resulting in increased OPEX and equipment maintenance. To solve these issues, optimize power supplies to reduce expenses and improve system efficiency.

Power Quality Challenges

As a Power Quality experts, they see challenges hindering reliable power delivery.

  • Sags/swells
  • Harmonic distortion and inter harmonics
  • Micro cuts and outages
  • spikes/transients
  • Undervoltage/overvoltage
  • Voltage imbalance (unbalance)
  • Voltage fluctuations (flickering)
  • Under/over frequency
  • Poor power factor

Using techniques like equipment maintenance, load balancing, and high-quality power supplies can minimize these issues. We must prioritize power quality management and invest in modern power systems to achieve a more sustainable and reliable power system.

Downtime cost for business

A 2018 survey found that one in four companies experience a power outage at least once a month in the US and power outages are becoming the, unfortunate, norm for businesses.

Data centers: studies show that the average cost of a data center outage has grown to $8,851 per minute

Manufacturing: a recent survey found that more than a quarter of manufacturing businesses experienced an outage at least once a month in 2017, with 58 percent reporting an outage lasting longer than an hour. For large manufacturing companies a single hour of downtime tops the $5 million mark

Retail: a power outage in a supermarket could see hundreds of thousands of dollars lost by perishable goods being spoiled by lack of refrigeration. For instance, a supermarket in Pennsylvania lost power for more than a day in February 2019. The owner estimated losses to be up to $30,000 in merchandise; for large retailers, that cost is even higher, reaching upwards of $5 million.

Market Trends

Globally, power systems are experiencing a transition toward decarbonization of electricity production through the large-scale deployment of central and distributed energy resources (DERs) based on renewables, which are gradually replacing conventional thermal plants.

The connection of DERs to the power system is mainly achieved using power electronic converters that can have both a positive or negative effect on power quality, depending on the type of disturbances evaluated and the control strategies applied.

In the future, power quality is expected to be significantly affected by this shift towards carbon-free power generation. Other trends threaten to degrade power quality further: the integration of many power electronics devices, the use of power cables at all levels of voltage, the increasing amount of fluctuating energy production and, finally, a reduced overall electrical systems stability.

Challenges & Measures to mitigate Poor Power Quality

As we transition towards a carbon-free power grid, several challenges threaten to degrade power quality. These include:
  •  While solar and wind power are crucial for sustainability, their intermittent nature can cause voltage fluctuations and frequency variations.
  • Proliferation of power electronics devices: Devices like variable speed drives and inverters inject harmonics into the grid, distorting the sine wave and causing equipment malfunction.
  • Extensive power cable networks: Long transmission lines introduce resistance and reactance, impacting voltage levels and increasing power losses.
  • Fluctuating energy production: The increasing reliance on weather-dependent renewables can lead to sudden changes in power generation, challenging grid stability.
  • Reduced system inertia: The retirement of traditional fossil fuel plants reduces the grid’s ability to resist frequency deviations.
Fortunately, various power quality and control solutions can mitigate these challenges:
Uninterruptible Power Supply (UPS):
  • Prevents data loss and equipment damage: A UPS provides instant backup power during power outages, protecting your electronic devices from sudden shutdowns and data loss. This is crucial for businesses that rely on their IT infrastructure for daily operations.
  • Safeguards sensitive equipment: Sensitive equipment like medical devices, communication systems, and industrial automation machinery require uninterrupted power to function properly. A UPS ensures smooth operation and prevents costly downtime.
  • Protects against power fluctuations: Even minor voltage fluctuations and sags can disrupt equipment and cause errors. A UPS filters out these fluctuations, providing clean and stable power to your devices.

Energy Storage Systems (ESS):
  • Store excess renewable energy and release it during peak demand, stabilizing grid frequency and voltage.

Power Quality Filters:
  • Eliminate harmonics injected by power electronics devices, ensuring clean power for sensitive equipment

Smart Grid Technologies:
  • Leverage real-time data and communication to optimize power flow, manage distributed energy resources, and predict potential problems.

Power Factor Correction (PFC):
  • Improve overall system efficiency by minimizing reactive power demand and optimizing power factor.

Dynamic Voltage Regulation (DVR):
  • Inject or absorb voltage in real-time to maintain constant voltage levels at critical points in the grid

Automatic Voltage Regulator(AVR):
  • Maintain Constant Voltage Output: The primary function of an AVR is to regulate the voltage output, regardless of fluctuations in input voltage or load changes. This ensures consistent power supply to connected equipment, preventing damage from undervoltage or overvoltage situations.
  • Protect Sensitive Equipment:Unstable voltage can cause surges, spikes, and dips, which can damage sensitive electronic equipment. An AVR acts as a safeguard, mitigating these voltage variations and protecting connected devices.
  • Improve Power Efficiency:Voltage fluctuations can lead to power losses within electrical systems. An AVR optimizes voltage levels, minimizing these losses and improving overall power efficiency.
  • Ensure Reliable Operation: Consistent voltage is essential for the reliable operation of electrical devices and systems. By regulating voltage, AVRs prevent disruptions and ensure smooth functioning of critical equipment.
  • Extend Equipment Lifespan: Voltage fluctuations can stress and wear down electrical components. An AVR reduces wear and tear by maintaining stable voltage, increasing the lifespan of connected equipment.
  • Reduce Downtime and Maintenance Costs: Voltage problems can lead to equipment failures and downtime. An AVR helps prevent these issues, reducing downtime and associated maintenance costs.

Microgrids:
  • Self-contained power systems integrating renewables and storage, providing reliable power and enhancing overall grid resilience.
