With the improvement of new battery storage technologies, the increase in the scale of Lithium ion battery production and the need to meet new services, due for example to the expansion of renewable energy sources of intermittent generation, solutions with batteries for renewable energy storage are more competitive every year.
BSLBATT Lithium, renewable energy storage battery supplier, has seen this panorama a few years ago and participates in research projects for the development of Lithium-ion batteries in China and containerized storage solutions.
BSLBATT batteries for renewable energy storage (called ESS) was developed to serve several systems connected to the grid both behind-the-meter and front-the-meter, and for off grid systems.
In places without grid connection, it is possible to implement energy micro-grids, which can be formed by various types of generators (diesel, photovoltaic, wind, SHP, etc.) and renewable energy storage batteries. There are still many countries and regions around the world that are eligible for energy microgrid construction, representing a huge potential market. Rural communities can benefit from the implementation of this Microgrid system and the internet allowing children to access better quality educational content through distance learning or a doctor to remotely assist a nurse.
Behind-the-meter applications can be leveraged by industrial, commercial, and even residential users for better management of the energy and power used in their renewable energy storage batteries. The most important applications are local self-consumption, peak shaving, energy time shift and backup.
Local self-consumption is given when the renewable energy storage batteries can generate all or part of the energy consumed through an intermittent source on its property. The surplus energy generated during the generation hours is stored for later use.
Peak shaving is important for consumers who need to reduce the amount of energy consumed in a certain period of time to avoid a consumption peak. An example of this is group A customers that are forced to contract a high demand just to attend eventual peaks with the risk of paying penalties if they exceed this value.
Energy time shift is an interesting application for customers that have to pay hourly posts. The use of renewable energy storage batteries would allow the surplus energy not consumed during a time slot to be stored for its later use in time slots with a higher tariff.
Finally the application of backup is interesting in places where the electricity supply is unreliable. This is important both for industry and for essential services where the lack of a backup system can lead to large economic losses.
For large plants with intermittent sources the emphasis is on after-the-meter applications, allowing the possibility of mismatching supply and demand and offering ancillary services to the grid, as well as reducing the uncertainty of energy supply.
BSLBATT renewable energy storage battery solutions
BSLBATT Lithium's ESS-Gird has three main components: the PCS (Power Conversion System), the battery pack and the BESS controller. In addition, it is equipped with an environmental control system, a fire protection system, an air conditioning system, and a local and remote control and monitoring system (Dynamic Energy Management System - EMS-RTU).
The system consists of a lithium-ion battery pack (LiFePO4 - Lithium-Iron-Phosphate) with a Battery Management System (BMS - Battery Management System), whose function is to monitor each cell in the pack to ensure safe operation of the battery system, respecting voltage, current and temperature limits. Different battery capacities can be customized to the specific needs of each ESS project.
BSLBATT's ESS-Grid is available in 10, 20 or 40 foot containers. Each container can have a capacity from 138 kWh to 2.5 MWh and a power from 50 kVA to 2 MVA.
