As distributed PV, energy storage, and other renewable energy resources continue to scale, distribution grids are evolving from traditional “one-way power delivery” toward two-way interaction between generation and load.
Connecting more renewables is only the first step. The next challenge is how to consume more renewable energy locally while maintaining stable and resilient grid operation.
DoGo focuses on grid-forming technology at the distribution level, addressing this challenge in three key ways:
01 | Increasing Local Short-Circuit Ratio and Strengthening Weak-Grid Stability
With a high penetration of renewables, some distribution networks face insufficient short-circuit capacity and reduced grid strength.
Grid-forming energy storage can actively establish and support voltage, strengthening the local grid and improving stability under weak-grid conditions.
02 | Local Voltage Management: Addressing Voltage Excursions and Oscillations
DoGo’s grid-forming energy storage brings voltage support closer to the distribution network, enabling fast and local voltage regulation through active and reactive power control.
On the one hand, for low-voltage issues at the end of distribution feeders caused by long lines and high impedance, grid-forming energy storage provides active voltage support to improve voltage levels.
On the other hand, when renewable generation and load fluctuations cause voltage variations and oscillations, the system responds dynamically to enhance voltage stability.
03 | Increasing Renewable Energy Consumption and Delaying Grid Expansion
When renewable generation is high, energy storage absorbs surplus power; during peak demand, it releases energy.
Through the coordinated operation of renewables + energy storage + grid-forming control, more renewable energy can be consumed locally, reducing reverse power flows and relieving local grid capacity pressure.
