Capacitor Bank
4.2.5 Switched capacitor bank for voltage balancing. One aspect studied in this paper is the use of switched capacitors for voltage support/balancing in a microgrid with unbalanced loads. The capacitor bank is designed based on commercially available capacitor units considering their ratings and switching logics [44,45].

If V = 1 Volt than C = Q, thus capacitance is defined as the amount of electric charge in coulomb required to raise its potential by one volt.. If V = 1 Volt than C = Q, and Q = 1 Coulomb than C = 1 Farad thus one Farad is capacitance of a capacitor which stores a charge of one coulomb when a voltage of one volt is applied across its terminal.

the voltage in the output capacitor drops; the control loop of the regulator senses the voltage deviation and tries to conduct more. This takes time (the load regulation response time in the datasheet), and during this, the voltage falls more. the regulator conducts more and pulls more current from the input capacitor.
