Voltage Control Using Inverter Reactive Power Control

This is the fifth of five articles in the series “Reactive Power in Utility-Scale Solar PV Applications.”

In the previous four posts in this series, we discussed what reactive power is and where it comes from, its impact on T&D systems, and inverter-based resources’ capabilities for reactive power injection and absorption.

As mentioned in Blog #2 of […]

Active Power Priority vs. Reactive Power Priority

This is the fourth of five articles in the series “Reactive Power in Utility-Scale Solar PV Applications.” Here’s the last article – “Inverter-Based Resources Reactive Power Capabilities” – in case you need to catch up.

In the earlier articles in this series, we’ve looked at the purpose of reactive power, power ratings of utility-scale solar inverters, and how […]

Inverter-Based Resources Reactive Power Capabilities

This is the third of five articles in the series “Reactive Power in Utility-Scale Solar PV Applications.” Here’s the last article – “Reactive Power and Transmission & Distribution Operations” – in case you need to catch up.

Inverters are a key component of any Inverter-Based Resources (IBR) facility, including utility-scale solar PV.  Because of their ability […]

Reactive Power and Transmission & Distribution Operations

This is the second of five articles in the series “Reactive Power in Utility-Scale Solar PV Applications.”

In Part 1 of this series, we looked at the differences and relationship between real, reactive, and apparent power.  We also looked at the production and absorption of reactive power by equipment such as transformers, reactors, and capacitors.

Before we […]

What Are Reactive Power and VArs?

This is the first of five articles in the series “Reactive Power in Utility-Scale Solar PV Applications.”

Right after I started my first job out of college, I found myself presenting at a meeting and talking about reactive power and VArs.  These were very senior-level engineers, and, although I didn’t recognize it at the time, never […]
