Assessment of Seasonal Variability for Resilience and Reliability Analysis of Grid Integrated Photovoltaic Systems for Energy Management

Photovoltaic systems play a crucial role in harnessing renewable solar energy, offering a sustainable solution to reduce reliance on fossil fuels and lower carbon emissions. This paper analyzes the seasonal variability of grid-integrated photovoltaic systems to assess resilience, reliability, and energy management efficiency. The study evaluates the loss of load expected across different seasons to measure system adequacy under fluctuating solar irradiance, electricity demand, and weather conditions. The study explores customer average interruption duration index, the system average interruption frequency index, and the system average interruption duration index, concerning the integration of solar power into the grid to ascertain its influence on the performance of the grid. Resilience grid dependency index is introduced to quantify the system's ability to recover from fluctuations resulting from seasonal variations in solar energy generation. Results highlight periods of increased grid stress, which serves as important parameter for efficient energy management system.
