Application of energy storage batteries in Mongolian base stations

Mongolia's heavily coal-dependent energy sector needs a BESS to achieve its decarbonization target. Coal-dependent energy system. As of end 2021, Mongolia had 1,549 megawatts (MW) of installed power generation capacity.

Since Mongolia's energy sector reform in 2001, the CES has been unbundled into generation, transmission, and distribution subsectors; and the government has introduced a single-buyer model for market-oriented sector operations. The Law on Investment was amended in 2015 to support private sector investment in energy infrastructure.

14 N-1 standard criterion is a design philosophy to enable the stable power supply in case of loss of a single power facility, such as a transformer and a transmission line. In conclusion, the BESS capacity was 125 MW/160 MWh.15 Table 4 summarizes the major applications of the BESS in Mongolia. Load shifting.

Some battery technologies are well suited to load shifting, for instance, because they can store a large amount of electricity, while other battery technologies are a good fit for grid stabilization because they can produce high power instantaneously.

Battery operational risks, such as the risk of fire or of shortened battery life, need to be mitigated during the BESS design stage and during the operational stage. Well-trained domestic BESS operators and a well-organized O&M strategy are key to sustainable BESS operations in developing countries.

In the current market, lithium-ion (Li-ion) batteries are the dominant technology for utility-scale grid storage, while other technologies, such as NaS batteries and redox flow batteries, also have proven track records in the market.
