Objective of compensation is to achieve stable operation when negative feedback is applied around the op amp. Miller - Use of a capacitor feeding back around a high-gain, inverting stage. Miller capacitor only Miller capacitor with an unity-gain buffer to block the forward path through the compensation capacitor. Can eliminate the RHP zero.
Instead of using capacitor banks, there is a different alternative to compensate the reactive power that is based on the use of synchronous compensators. These are synchronous machines that, operating with null active power, can behave either as variable capacitors or coils, by simply changing their excitation current .
However, although reactive power compensation can reduce the three-phase unbalance by increasing the power factor, when the three-phase unbalance is very serious, the reactive power compensation will not completely solve the three-phase unbalance problem , and reactive power compensation device need high cost .
Miller capacitor with an unity-gain buffer to block the forward path through the compensation capacitor. Can eliminate the RHP zero. Miller with a nulling resistor. Similar to Miller but with an added series resistance to gain control over the RHP zero. Feedforward - Bypassing a positive gain amplifier resulting in phase lead.

Once the problems of reactive power generation, transmission and distribution have been exposed, we will proceed to describe the actions that the customers can adopt in order to avoid or minimize the corresponding penalization in the electricity bill. These actions are covered by the denomination ‘reactive power compensation’.
