| description | More photovoltaics are deployed at distribution networks and these noticeably cause voltage fluctuations in the distribution system. Use of smart inverters (SIs) is investigated as they enhance grid stability with voltage and frequency support. However, these potentially beneficial operating modes of SIs and their impact on the power system operation are not well-known. Conventional simulation packages do not have the tools to run simulations with these inverters. In order to fill this gap and investigate these points, a brand-new simulation platform called Solar Resource Application Platform for Grid Simulation (Sora-Grid) is being developed. In this paper, Sora-Grid's additional capabilities and its unique approach to integrating SIs into the power flow calculations are presented. Some simulation works have been undertaken to show its operation. Furthermore, the results give an insight into understanding the behaviors of SIs and how they impact the distribution grid operation. A typical distribution network with several residential houses is modeled, and the impact of changing operating conditions and active power output on the system voltage is investigated. Finally, a mathematical model is developed to optimize the SI capacity. The optimum point ensures that maximum solar energy is captured, while fair operation is maintained. |
