On the verdant grass slope, wind turbines convert the kinetic energy of the wind, while photovoltaic panels capture the thermal energy of the sun. Next to the white energy storage box lies the "heart" of this distributed energy system - a small smart transformer.
The DC power output from photovoltaic panels experiences significant voltage fluctuations after being inverted. The electrical energy from wind turbines is outputted through frequency conversion, with parameters that are not fixed. This transformer serves as both an "adapter" and a "transfer station". As an "adapter", it adjusts the wind and solar power to a voltage and frequency compatible with the energy storage box, ensuring that green electricity is stably stored in the energy storage cabin. As a "transfer station", when the grid requires energy replenishment, it steps up the stored electricity to the transmission standard, allowing it to be smoothly connected to the public grid.
Unlike traditional transformers, it is compact in size and adaptable to outdoor environments. The chip can match the fluctuations in wind and solar power output in real time, allowing decentralized green electricity to be both "stored on-site" and "transmitted on-demand". It is this small and compact controller that keeps the energy from wind and solar from being "scattered and drifting", turning it into a flexible and callable reserve of clean electricity.
