Local Situation Analysis
Stabilizing the Grid and Optimizing Renewable Energy Use
California is at the forefront of renewable energy development in the United States, with abundant solar and wind resources. However, as renewable energy capacity grows, power fluctuations and curtailment of wind and solar power have become significant challenges, impacting grid stability. To address these issues, energy storage systems have become essential. The 200MWh energy storage site integrates storage with solar power generation, effectively balancing energy supply and demand, smoothing renewable energy output, and reducing curtailment. Additionally, this project explores the application of renewable energy in the spot market, providing robust technical support for California’s energy transition and grid reliability.
Peak Shaving and Valley Filling
Smart Energy Storage Balances Supply and Demand
The peak shaving and valley filling strategy enables the energy storage system to charge during high solar output periods (typically daytime) when grid demand is low and discharge during low solar output periods (such as nighttime) when grid demand is high. This approach helps balance the supply and demand of the grid, reducing reliance on costly peak electricity and enhancing the economic and operational stability of the power system.
