Energy Storage System
Innovative Integration of PV and Energy Storage for Optimized New Energy Applications
Located in California, USA, the local power supply faces challenges such as the volatility of renewable energy, wind and solar curtailment, and grid stability. Photovoltaic generation s output fluctuations need to be managed to ensure a stable power supply. Additionally, issues with overgeneration and insufficient grid capacity require addressing. Grid stability is crucial, with energy storage systems providing essential frequency regulation and backup capacity. Managing peak power demand and optimizing charge and discharge strategies to handle price fluctuations in the spot market are also key challenges.
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.
