The integration of renewable energy into modern power systems is
essential for achieving sustainability goals; however, seasonal
variability in renewable generation and electricity demand continues
to present operational and economic challenges. This study assesses
seasonal renewable energy integration using real-world photovoltaic
(PV) generation, electricity consumption, battery storage, and
dynamic electricity pricing data. A quantitative data-driven
approach was employed to evaluate seasonal variations in renewable
generation, electricity demand, storage performance, and economic
outcomes. Renewable penetration, energy balance, battery
utilization, and cost-saving indicators were calculated, while the
Kruskal–Wallis test and Spearman correlation analysis were applied
to examine seasonal differences and inter-variable relationships. The
results revealed significant seasonal variations in renewable
generation, electricity consumption, and electricity prices (p <
0.001). Summer achieved the highest renewable penetration rate
(51.53%) and the greatest economic benefit, with renewable energy
offsetting 43.26% of seasonal electricity costs. In contrast, winter
and autumn exhibited lower renewable penetration rates and greater
dependence on grid electricity. Battery storage analysis
demonstrated substantial contributions to system flexibility, with
storage utilization ranging from 40% to 75% across representative
operating profiles. Furthermore, renewable generation was
consistently negatively correlated with electricity prices,
particularly during spring and summer, indicating its potential to
reduce market price pressure. The findings highlight the critical role
of battery storage and adaptive energy management strategies in
enhancing renewable energy integration under seasonal variability.
This study provides valuable insights for policymakers, utilities, and
energy planners seeking to improve renewable energy utilization
and support the development of resilient and sustainable energy
systems.
