In this paper, a new design of power supply is presented that provides a stable output voltage (Vout = +12 V, 0 V, -12V) over significant range of input voltage variations (Vin = +15 V to +50 V) emulating the variation of output voltage of PV systems. . Although the data-driven static voltage stability problems have been widely studied, most of the classical algorithms focus more on improving the accuracy of the system prediction, ignoring the error classification errors generated during the prediction process. However, the generated DC power from PV systems is not stable due to weather, atmospheric and environmental conditions, which requires the design of a DC power supply. . Therefore, the increasing penetration of PV may impact a system's oscillations negatively as PV units add additional dynamics to power systems. Therefore, it is essential to analyze a systems behavior before replacing conventional generators by large-scale solar PV units. Solar power generation is gaining popularity as a renewable energy source these days. The RAM study focused on three subsystems: Balance of System (BOS), photovoltaic modules (PV modules), and inverters.
