How does reactive power work?

To deliver reactive power only, the voltage source connected to the main grid through a reactance has to generate a voltage in phase with the grid voltage but with higher amplitude. To absorb reactive power, it will generate a voltage still in phase with the grid voltage but with a lower amplitude.

What is the difference between active and reactive power?

Unlike active power, reactive power does not contribute to actual work but is vital for supporting voltage levels and ensuring efficient transmission and distribution of electrical energy. Its measurement unit is VAR, and it can be either absorbed or supplied by devices such as capacitors, reactors, and synchronous generators.

What is dynamic reactive power?

For dynamic reactive power, the renewable energy generators rely upon the IBRs and additional reactive power compensation through other dynamic reactive power devices e.g., SVCs and STATCOMs. The developer of a renewable energy plant has to trade-off between primary IBRs or additional reactive power compensation devices.
