An amendment to the IEEE standard on interconnecting distributed resources (DRs) with electric power systems (EPSs) permits reactive power control upon mutual approval by EPS and DR operators and their agreed-upon coordination [1]. Therefore, this study investigates the maximum effect of reactive power control such as the Volt/Var control of distributed generation on the voltage regulation of practical...
As distributed generation (DG) has been deployed in radial distribution networks, it changes their steady-state and transient behavior. To analyze the potential impact of DG on the distribution network, this study models a distribution network enhanced by the DG system, particularly the photovoltaic (PV) system, in the Digital Simulation and Electrical Network Calculation Program (DIgSILENT) and the...
Grid-connected photovoltaic (PV) systems with relatively high capacity effectively reduce peak load, but because of their reverse power flow, they can cause overvoltage along a feeder that can exceed five percent of the rated voltage. Modern PV systems with the capability of Volt/Var control can mitigate overvoltage by either injecting or absorbing reactive power. Thus, the objectives of this study...
Various distributed generation (DG) systems with capacities in the range of several kilowatts to tens of megawatts can increase voltage along a feeder when they are injecting power into distribution systems. Thus, the main objective of this study is to analyze the transient behavior of such a distribution system integrated by DG systems. This study (1) models the IEEE 37-bus test feeder as a distribution...
One of the main concerns of utilities is overvoltage along their feeders when they enhance their networks by various distributed generation (DG) systems. The objective of this study is (1) to near-optimally allocate locations and capacities of DG systems on distribution networks at peak load and (2) to analyze the impact of DG inverters with the capability of volt/var control on the improvement of...
