In the long process of energy development, lead-acid batteries have long been at the edge of the traditional power system, playing a supporting role. However, with the advent of the era of smart microgrid, this ancient energy storage technology is experiencing a remarkable counterattack, and gradually become the core component of the smart microgrid architecture, profoundly rewriting the power pattern.

## The supporting role of lead-acid batteries in the traditional power system

In the traditional centralized power system, large thermal, hydraulic and nuclear power plants are the protagonists, which support the entire grid with stable and large-scale power output. Lead-acid batteries are mainly used in some backup power supply scenarios, such as the short emergency power supply of telecommunications base stations in the case of a mains power outage, or to provide instant high current when the car engine starts. Its function is limited to responding to sudden power outages and maintaining basic power supply, and its capacity and performance are difficult to be compared with the main power supply system. It only plays a limited role in ensuring the local reliability of the power system, and its presence is low.

## Smart microgrids bring transformative opportunities

The rise of smart microgrids has completely changed the pattern of energy supply and demand. Microgrids integrate distributed energy resources, such as solar photovoltaic panels, small wind turbines, etc., which are subject to natural conditions and have intermittent and fluctuating power generation. Solar energy relies on light, and its output drops sharply at night or on cloudy days. Wind power depends on wind speed, which causes power output to fluctuate. This is in sharp contrast to the stable generation curve of the traditional power system, which brings great challenges to the stability and reliability of the power supply. The energy storage technology has become the key to solve this problem, and the lead-acid battery has ushered in the opportunity of counterattack with its own characteristics.

## Lead acid battery counterattack advantage

1. ** Cost advantage ** : After more than 100 years of development, the production process of lead-acid batteries is mature, and the raw material lead resources are rich and widely distributed. Compared with emerging energy storage technologies such as lithium-ion batteries, the initial investment cost of lead-acid batteries is low, and for small micro-grid projects with limited budgets and cost sensitivity, especially off-grid micro-grids in developing countries or remote areas, lead-acid batteries can build energy storage systems at a lower cost in the early stage of construction, becoming the preferred solution.

2. ** High safety ** : In battery applications, safety is crucial. The electrolyte of the lead-acid battery is sulfuric acid aqueous solution, and the chemical properties are relatively stable, and there is no risk of combustion or even explosion that may be caused by overcharge and overheating like lithium-ion batteries. In the smart microgrid environment, many distributed power supplies and energy storage devices are densely connected, and any security risks may trigger a chain reaction. The reliable security of lead-acid batteries enables them to operate stably, ensuring the safe operation of microgrids and reducing safety concerns during operation and maintenance.

3.** Strong compatibility **: Smart microgrids are often a mixture of a variety of energy sources and power equipment, and the compatibility between different devices affects the overall performance of the system. Lead-acid batteries have accumulated rich practical experience in long-term application, and have good compatibility with various distributed power supplies and electrical equipment interfaces. Whether it is connected with common photovoltaic inverters, or matched with AC and DC loads, it can work smoothly together without complex adaptation transformation, reducing the difficulty and cost of microgrid system integration, and promoting the rapid construction and flexible expansion of smart microgrids.

## Technology upgrade to strengthen the core position

In order to better adapt to the needs of smart microgrids, lead-acid batteries are also undergoing continuous technological innovation. On the one hand, researchers improve the charging and discharging efficiency and cycle life of the battery by improving the plate material and structure. For example, the new lead alloy plate reduces the internal resistance, reduces the energy loss during the charging process, enables the battery to store and release electricity more efficiently, and the number of cycles has been increased from hundreds to thousands of times in the past, greatly enhancing the economy of long-term energy storage applications in microgrids. On the other hand, an intelligent management system is introduced into the lead-acid battery pack. These systems can monitor battery voltage, current, temperature and other parameters in real time, accurately control battery charge and discharge according to the power supply and demand of the microgrid, avoid overcharge and overdischarge, extend the service life of the battery, and optimize the overall power dispatching of the microgrid, so that the lead-acid battery can work closely with other components to maximize efficiency. Further solidify its core position in smart microgrids.

From a silent supporting role in the traditional power system to an indispensable core in the smart microgrid, lead-acid batteries have achieved a magnificent counterattack with cost, safety, compatibility advantages and technological upgrades. With the acceleration of the construction of smart microgrids around the world, lead-acid batteries will continue to glow and heat in the field of energy storage and power regulation, promoting the power industry to a greener, intelligent and reliable direction, and opening a new chapter in energy utilization.
