Microgrid/Energy Storage Solution

As a leader in wind and solar energy storage and microgrid technology, Yihe provides users with intelligent microgrid solutions. Intelligent microgrid is a small modular and decentralized energy supply network based on distributed generation technology, which achieves power load and power quality management on the user side. It can achieve integrated operation of internal power and load, and can smoothly connect to the main grid or operate independently and autonomously through coordinated control with the main grid, meeting the user's requirements for distributed power supply access, power quality, power supply reliability and safety.

Scheme Architecture

Scheme Introduction

Smooth power

The discharge power of the energy storage system changes with the load, resulting in a smoother usage curve and improved power quality.

Multi energy synergy

Multi energy complementarity, balanced power supply, improved stability of power generation, and improved plannability of microgrid scheduling

Peak shaving and valley filling

The energy storage power station adopts a dual charging and discharging method, namely low charging and high discharging, and flat charging and high discharging

Emergency backup power

This system uses containers as carriers and motor vehicles as transportation tools to replace traditional diesel generators
