Description of the project : Renewable energy is on the rise all over the world. The biggest challenge in doing so, would be, i m y opinion the grid stability. If we talk about photovoltaic Integration in the exsisting grid, the control guidlines are very strict in regards to Active and Reactive Power control (Frequncy and Voltage of the grid).

Power plant controllers (PPC) help integration of solar farms to the medium and high voltage levels. These PPC's are usually a PI controller which in most cases in manually tuned.

I'm trying to automate this process with some kind of online tuning method for the PI controller.

Needs suggestions for Self-Tuning Algorithoms that would get the optimal values for Kp Ki for the controller with a step test (as most of the Grid operaters allow it during commisioning of the project).

Books, research papers and sort of links would be appriicated. Just point me in the right direction

Thank you
