Introduction to terms In AC circuits, the current absorbed by a load can be represented by two components: active component I R and reactive component I Q. The active component I R, in phase with the supply voltage, is directly related to the output (and therefore to the part of electric energy converted into energy of different types: …
About Photovoltaic Energy StorageCapacitors are made within a given tolerance. The IEEE standard allows reactive power to range between 100% and 110% when applied at rated sinusoidal voltage and frequency (at 25 C case and internal temperature) (IEEE Std. 18-2002).
