The role of BESS
Battery energy storage system(BESS) can store electrical energy. It can be used as an emergency energy source, as well as for energy storage when the load on the grid is low and energy output when the grid is high, for peak shaving and valley filling, to reduce fluctuations in the grid.
Application scenarios of BESS
1. Backup energy storage
Battery energy storage system(BESS) can secure grid stability in the power supply system. Moreover, unstable production (short-term intermittency and imbalance of supply/demand) of solar energy can be mitigated through ESS.
BESS helps to effectively use and manage your energy that leads to the reduction of the electricity bill. According to the charging system of each country, various solutions can be configured and applied, for example: charging a battery with low-priced night time electricity and cutting electricity cost by lowering peak demands.
2. Photovoltaic energy storage
BESS can be used in the field of photovoltaic energy storage due to its safe and stable performance, and the cost of solar power generation can be greatly reduced. Lithium batteries play both an energy regulating and load balancing role in the system, converting the electrical energy output of the PV system into chemical energy storage for use in times of power shortage.At present, it is mainly used in scenarios such as photovoltaic power stations.
3. Distributed energy storage
BESS can regulate the load regulation of microgrids, improve the economic efficiency of microgrid systems, solve the mismatch between peak power consumption and peak power generation, give full play to the flexible and fast response capability, and realise the optimal allocation of power resources. Therefore, Lithium battery ESS can be applied in the field of distributed energy storage, currently mainly around distribution grids, including distribution network access points where distributed PV is centrally connected, as well as distribution network systems within large commercial and industrial enterprise users.
The above is a brief introduction to application scenarios of BESS. BESS can help us manage energy and reduce electricity bills.
