| Abstract. When designing an optimal autonomous power supply system for residential houses or other individual objects located far from the main distribution networks, it is essential to consider the variability of the load, especially when utilizing renewable sources like photovoltaic (PV) solar panels and wind generators. Proper modeling of the stochastic nature of the load is crucial for ensuring that the demand within the microgrid is met effectively using renewable energy, supported by Battery Energy Storage Systems (BESS) and voltage regulation devices. Addressing this challenge can significantly enhance the reliability and sustainability of off-grid systems that prioritize renewable energy sources. Simulations are conducted over three consecutive days with limited sunlight during the year, and the resulting data are analyzed to assess their impact on system performance and battery life. The modeling was performed using PVSyst software version 7.3. The findings underscore the importance of considering load fluctuations in the design and operation of stand-alone residential PV systems. The paper offers insights into how these systems can be optimized to mitigate the adverse effects of load variability, thereby enhancing their overall efficiency and longevity. |
