What is the primary purpose of reactive resources in an electrical system?

The primary purpose of reactive resources in an electrical system is to maintain acceptable voltage levels. Reactive power is essential for voltage regulation across the power grid. It supports the voltage needed for the current to flow through the transmission system. When there is a demand for active power (real power), reactive power helps to ensure that voltage levels remain stable, preventing drops that can lead to power quality issues and possibly outages.

Maintaining voltage is crucial for the proper functioning of electrical equipment and the overall reliability of the power system. Adequate levels of reactive power help in mitigating voltage fluctuations caused by changes in load or generation. Proper management of reactive resources is integral to operations within the North American Electric Reliability Corporation (NERC) framework, ensuring that the grid operates efficiently and safely under varying conditions.
