Sorry, but I didn't understand how you implemented one OLTC in a simple case in order to control the voltage, centrally?
Could you please introduce one of the ways of that you told and also explain the following sentences, if possible: "there are numerous ways to compute the updates to the tap settings", "Except for a very simply case with a tiny number of OLTC and controlled voltages, finding an optimal (or even function) strategy for the updates would probably require deriving formulae for the sensitivities and implementing an update scheme based on them".
