Project Overview
Available Only Through Renon Power
Florida’s 10MWh Solar-Storage Project Boosts Clean Energy Development
Stabilize Solar, Mitigate Fluctuations, and Maximize Renewable Energy Utilization!
Florida, known as the Sunshine State of the United States, boasts abundant solar resources, making it an ideal location for developing photovoltaic (PV) power generation. However, as renewable energy generation increases, the instability and volatility of solar power have become more pronounced. The local grid often faces situations where solar power generation exceeds demand, leading to significant curtailment of wind and solar energy, which affects the actual utilization of renewable resources. To address this challenge, the construction of the 10MWh PV facility with integrated energy storage in the region is particularly important.
Enhancing Predictability and Reducing Fluctuations
Smooth Output, Predictable Power
Peak Shaving and Valley Filling:
The energy storage system stores energy generated by the PV system and is ready to supply power to the grid when needed. This makes the power output of the project predictable for grid operators and allows it to be time-matched with demand.
Smoothing Output and Reducing Daily Forecast Curve Error:
By configuring an energy storage system with a certain capacity in the renewable energy power plant, and conducting reasonable discharge scheduling based on the power output forecast, the energy storage system can adjust its charge and discharge status in real-time as needed. This smooths the power output of the PV plant, limiting its fluctuation within a certain range.
