Grid Stability: The energy storage system stabilizes wind-solar output fluctuations, ensuring grid reliability. Efficiency Improvement: The integrated model boosts renewable energy utilization to over 95%, increasing annual power generation by ~12%. Economic Benefits: Peak-valley arbitrage and ancillary services enhance internal rate of return by 3-5 percentage points. Environmental Impact: Annual savings include 799,500 tons of standard coal, reducing CO₂ by 2,181.6 tons, NOx by 469.37 tons, soot by 83.9 tons, and SO₂ by 419.54 tons, setting a green development example for desertified regions.
