Connections and composition of LV/MV/HV capacitor banks
If the power of the capacitors (in kvar) is less than 15% of the power of the transformer (in kva), choosing a fixed capacitor bank will definitely provide the best cost/savings compromise. If the power of the capacitors (in kvar) is more than 15% of the power of the transformer, a step capacitor bank with automatic regulation must be chosen.

Placing capacitors in parallel increases overall plate area, and thus increases capacitance, as indicated by Equation ref{8.4}.

Current when capacitor and resistor placed in parallel?
The capacitor and resistor are connected in parallel so I think that the resistor will draw a current I=VR but the capacitor is an ideal one therefore has no resistance and therefore draws an infinite amount of current which eventually stops when the capacitor is completely charged so overall. There is a subtle problem here with the logic.
