Micro Grid

The micro-grid is to reduce the scale of power generation, transmission, distribution, and power consumption of traditional power grids, and then plus modern scheduling and management to achieve specific needs in the region. With the rapid advancement of technology in decentralized energy and energy storage systems, small micro-grids can be from Smart home appliance, home energy management, household energy storage, electric vehicles, and household renewable energy combined into a household micro-grid, which expanded to combine large-scale renewable energy, building energy management systems, emergency power-generation systems, large energy storage systems, and regional distribution systems to form a community micro-grid or urban micro-grid.


Tatung provides the forward-looking energy solutions for micro-grids that reduce external power dependence and move toward energy autonomy

We expected to achieve following benefits:

▲ Economic benefits: Using renewable energy in the region for self-power production and combining with energy storage could reduce the purchase of utility power effectively, achieve lower the contract capacity, and save electricity costs.
▲ Environmental benefits: Using renewable energy could lower the emissions of fossil fuel and reduce the greenhouse effect.
▲ Energy-saving benefits: Replacing traditional energy sources with renewable energy, to increase the proportion of independent energy and clean energy, reducing the loss of long-distance transmission of electricity, as the result to achieve energy conservation.
▲ Social benefits: Power can be used and produced at the same place, which can solve the shortcomings of the power infrastructure. It has the potential to promote social and economic development for the areas with natural disasters and power outages.
▲ Reliable benefits: When mains supply is normal, micro-grid will become self-management to reduce the impact from power generation uncertainty, and increasing the penetration rate of renewable energy. When mains supply failure, micro-grid can operate independently, and the power supply can be used in emergency to improve reliability of power generation.

Service Structure

Micro-grid is composed of small-distributed power generation, power distribution equipment and energy management, load management, energy storage management and backup power. The system can balance power generation, load and energy storage at any time to maintain power supply, stabilize voltage and frequency. Power parameters can predict the load and power generation through the system to adjust the management mode of the energy storage equipment and optimize the overall power consumption.
