Front of Meter ： Randomness, volatility and intermittency of renewable energy. The inertia of the power grid is relatively reduced and the frequency regulation capability is insufficient.

Utility Side：The change of power energy structure and power load leads to the instability of power power grid and short - term shortage of capacity. The problem that power facilities need to be upgraded is increasingly prominent.
