Inverter Controller SchemeThe commonly used (Proportional-Integral) PI controllers arechosen in the design of inverter controller. The proposed scheme forinverter controller is shown in fig. 3. PLL based control approachis used to maintain synchronization with PCC voltages.Table 1: System Parameters and Load Details When Load isGreater Than GenerationParametersWithout invertercontroller(0

ConclusionA proposed concept of optimal utilization of a inverter (virtuallyinactive during night time in terms of active power generation)as a STATCOM has been proposed and validated throughMATLAB/Simulink simulations. The inverter is used to regulatethe distribution voltage at grid bus within utility specified limits.The proposed strategy of voltage control device will facilitateintegration of more power plants in the system without anyadditional voltage-regulating devices. This novel strategy impliesoperating power plant as a generator during the day [providingmegawatts (MW)] and ancillary services provider at night[providing mega volt amperes (MVARS)]. It is worth noting thatgrid codes typically do not allow DGs to manage the PCC voltages,this is considered to be the task of utilities. These aspects areoutside the scope of the paper.References[1] V. Khadkikar, A. Chandra, A. O. Barry, T. D.
