However, this surge in usage has brought forth a challenge in the form of voltage variations that can potentially lead to power losses and disrupt the overall stability of the grid. To address this crucial issue and enhance grid stability within high-penetration photovoltaic systems, the development of an adaptive scheme for controlling volt-ampere reactive (VAR) becomes imperative. This research extends the adaptive VAR control algorithm from single-phase to three-phase circuits, while assuming a balanced load. Subsequently, the modified control strategies are rigorously tested on a realistic multi-branch test feeder using a cutting-edge Real- Time Digital Simulator (RTDS). This comprehensive testing encompasses diverse load scenarios, both with and without the influence of a proportional-integral (PI) controller. Furthermore, the efficacy of these refined algorithms is assessed on two distinct but interrelated systems: the standalone PV system and the integrated PV-Battery system, using the well-established IEEE 13-node Test Feeder. These simple and low computational VAR control algorithms and PI controller algorithm can be implemented in real-time via low-cost and low power devices, such as digital signal processors (DSP) to perform global, local measurements and adaptive controls.
