Do all power plants generate power in essentially the same way
So heres''s the crazy part - Photovoltaic solar inverters are able to adjust their solid state IGBT''s timing with so much precision and power that they can simulate the rotating mass and generate reactive power just like the conventional power plants. They can equally consume reactive power (to help reduce grid voltage when it runs high), even while exploring active power.

Can a Battery Act as a Reactive Power Compensator in Energy
While most batteries store and discharge active power, providing reactive power may require additional equipment or control strategies that some battery systems do not support. An example can be found in studies like that of Li et al. (2021), which highlights the need for advanced inverter technology for effective power management.

Where does Reactive Power "go"? : r/ElectricalEngineering
Reactive Power does indeed go "back and forth" as most people are saying, but there is another way to think about it that I think is a bit easier. Reactive Power is needed (and is used) by many devices to work properly. The best example is the motor: a motor spins because of a magnetic field, and that magnetic field needs to come from somewhere.

Does a battery affect reactive power?
Since a battery is DC it only stores or releases real power the battery itself won't affect reactive power. However like any other DC source the connection to the AC system can be used to correct PF or provide reactive support. The reactive power means that there is an ac component of current which delivers and restore power repetitively.
Is it possible to provide reactive power from a battery alone?
It is not possible to provide reactive power from a battery alone. You can provide reactive power to the grid by grid connected inverter whose current is controlled to be in phase quadrature with the grid voltage. The reactive power is stored in the reactive elements in the grid, but is it withdrawn from the power stored in the battery.

What is reactive power?
Reactive power is simply energy that is being stored in the load by any capacitors or inductors inside it. It can be returned to the source and indeed does so on a cycle-by-cycle basis in linear AC systems. The terms are just a way to simplify the analysis of AC power systems.
What is the difference between active power and reactive power?
Reactive power is in quadrature with active power and does not contribute in active power flow. DC power at the inverter input can be fully utilise to supply AC kW. Reactive power comes from the DC capacitor used at the inverter input.
