The Voltage stability analysis for grid-connected PV system using optimized control tested by IEEE 14 &30 bus system

Abstract

In the research work presented in this paper, we present a grid-connected solar photovoltaic (PV) system, which is focused on various factors, such as the low oxide emission and high energy efficiency of the system. Solar PV systems have a greater impact on grid stability than any other energy source. IEEE 14 bus test system is used to verify the voltage stability of the bus. It is a concept of a methodology using a RNN-based PV controller in conjunction with a Landsman converter to maintain the PV system's voltage-gain ratio and improve it. Conversely, an ANN-based boost Integrated Landsman Converter improves the solar photovoltaic voltage connected to the grid. In addition, continuous monitoring of solar plants (irradiation, sunlight & voltage) is implemented through the Internet of Things (IoT). A grid voltage stability and analysis is taken by 14 buses, five generators and 12 loads test system is tested. The proposed two methods have been proven to be effective regarding the uncertainties related to loading demand. This approach offers voltage stability for grid-connected PV systems in industrial sectors. The IEEE 14 & 30 bus system tested this work using MATLAB simulation.
