Energy storage systems play a critical role in enhancing grid stability by providing several essential services:
Key Contributions to Grid Stability
- Balancing Supply and Demand: Energy storage systems can absorb excess energy generated during periods of low demand and release it during peak demand times, helping to maintain a consistent balance between supply and demand.
- Frequency Regulation: They provide critical stability services by regulating frequency, which is essential for ensuring that the grid operates within a stable frequency range. This prevents disruptions and maintains a balance between supply and demand.
- Voltage Support: Energy storage devices can inject or absorb reactive power to regulate voltage levels, preventing equipment damage and power outages. This ensures that electricity is delivered within acceptable limits to consumers.
- Integrating Renewable Energy: Energy storage facilitates the integration of renewable energy sources by storing surplus energy generated during periods of high production and releasing it when production is low; this ensures a continuous and reliable supply of renewable energy to the grid.
- Enhancing Grid Resilience: Energy storage helps support distributed energy resources (DERs) like rooftop solar panels, reducing stress on distribution infrastructure and enhancing overall grid resilience.
