We define the reactive power to be positive when it is absorbed (as in a lagging power factor circuit).. a. Pure capacitance element – For a pure capacitance element, P=0 and I leads V by 90° so that complex power is:. S = jQ = (V ∠0°) (I ∠90°) S = V×I ∠−90° S = −jV×I. Thus the capacitance element generates reactive power.

About Photovoltaic Energy StorageIn some cases, special circuits are used to measure the reactive power. For example, the reactive power measurement can be performed with compensation capacitors to determine the amount of reactive power compensation. Here, capacitors are added or removed to minimize the phase shift angle and thus compensate for the reactive power.
