Smart Grid Solutions
Enhancing Grid Resilience with Instantaneous Power Intelligence
Overview
As the global energy structure shifts towards renewables, grid stability faces unprecedented challenges from intermittent wind and solar power. STC’s Dry-Electrode AHSC Supercapacitor systems provide the critical sub-second response needed to stabilize modern smart grids. By buffering high-frequency fluctuations and providing peak power, we ensure a seamless, reliable, and efficient flow of electricity.
Core Applications
Frequency Regulation & Primary Frequency Control
STC AHSC supercapacitors respond in milliseconds to grid frequency deviations, providing active power support far faster than traditional chemical batteries or mechanical systems. This prevents large-scale outages and maintains grid synchronization.
Renewable Energy Smoothing
Smooth out the "ramp rate" of solar and wind energy. Our systems absorb sudden surges and fill in momentary drops, allowing renewable plants to meet strict grid-code requirements and reduce curtailment.
Peak Shaving & Load Levelling
Reduce the strain on transformers and substations during peak demand. By discharging during high-load periods and recharging during low-load periods, STC helps utilities defer expensive infrastructure upgrades.
Voltage Support & Power Quality
Compensate for voltage sags and swells instantaneously, protecting sensitive industrial equipment connected to the smart grid from power disturbances.
