Grid Integration refers to the entire process of effectively integrating battery energy storage systems (BESS), renewable energy sources (such as wind and solar power), or distributed resources like electric vehicles, and coordinating their operation with the power system (grid). The goal is to enhance the flexibility, stability, and the ability to absorb renewable energy of the system.
The grid integration functions of the energy storage system:
Frequency Regulation: Provides a second-level response to stabilize frequency
Voltage Support: Enhances local voltage stability through reactive power regulation
Peak Shaving: Reduces peak load and delays the investment in expansion of transmission and distribution
Increasing the penetration rate of renewable energy: Smooths fluctuations, mitigates waste of wind and solar energy
Black Start: Starts the power grid under the condition of no external power after a major power outage
