About Photovoltaic Energy StorageThis paper explores the method of reactive power compensation using shunt capacitors for two cases. The first case involves a load fairly close to the AC source. The shunt capacitors are injected into the circuit by a logic circuit which uses the reactive power absorbed by the load, which are inductive in nature, as its input. The second case …
About Photovoltaic Energy StorageSeries compensation is the method of improving the system voltage by connecting a capacitor in series with the transmission line. In other words, in series compensation, reactive power is inserted in series with the transmission line for improving the impedance of the system. Thus, it improves the power transfer capability of the line. Series …
