Energy Storage System
Battery Energy Storage System refers to a system that uses batteries to store electrical energy for later use. BESSs play a vital role in various applications, including renewable energy integration, grid stabilization, peak shaving, load shifting, backup power, and microgrids. Here are some key aspects of Qmax’s Battery Energy Storage System:
BESSs store electrical energy in rechargeable batteries, typically using lithium-ion (Li-ion) batteries due to their high energy density, efficiency, and cycle life. This has a high advantage over the traditional lead acid batteries.
BESSs play a critical role in renewable energy integration. They can store excess energy generated from renewable sources, such as solar or wind, during periods of high generation and supply it back to the grid or the connected system during periods of low generation. This helps to balance the intermittent nature of renewable energy sources and ensure a stable power supply.
BESSs can provide grid stabilization services by injecting or absorbing power rapidly. They can help regulate the frequency and voltage of the electrical grid by responding quickly to grid imbalances, fluctuations in demand, or sudden changes in generation.
BESSs can be used to shift electricity consumption from peak to off-peak periods by charging the batteries during low-demand periods when electricity prices are lower and discharging them during peak-demand periods. This helps reduce the overall electricity costs and optimises energy usage.
BESSs can provide backup power during grid outages or as an uninterruptible power supply for critical systems. They can ensure a continuous power supply for essential services, such as hospitals, data centers, or residential applications.
BESSs are used in micro-grid applications, where they integrate with renewable energy sources, diesel generators, or other power sources to provide reliable and clean power to isolated or remote areas that are not connected to the main electrical grid.
