Since safety certification only applies for lithium-ion battery system up to 48V in Chinese Coal Mine Industry for underground application, standard battery energy storage system (BESS) cannot be directly used to provide emergency power for critical motor load such as fan / pump etc, which are normally rated at a few hundreds volts. This paper develops a modular design defined as Battery Electronic...
The microgrid technology provides a desirable way and an opportunity to reduce the burning of fossil fuels. It also has important significance for utilizing and developing new energy. In this paper, the distribution generation is considered to provide electrical energy in a microgrid and the distribution generation devices mainly include the photovoltaic cell, wind generator and the energy storage...
An industrial power management system containing MW sized energy storage under smart grid control concept has been designed to meet the needs of modern coal mines and related society. The smart coal mine power system brings three basic benefits to operations: 1. Increased power robustness & reliability through systematic design and optimization; 2. Operational efficiency improvements through the...
