Mobile energy storage power station: a flexible and versatile new choice for energy management.

With the acceleration of the economic and social transition towards comprehensive green development, the supply and demand structure of energy is gradually showing diversified characteristics. This diversity is not only reflected in the continuous increase of energy types, but also encompasses multiple aspects such as the wide range of energy sources and the continuous improvement of energy utilization.

In the complex energy field, mobile energy storage technology, with its outstanding flexibility, reliability, large capacity, easy installation method, and excellent scalability, is like an expert in energy management, always on standby, providing solid guarantees for the instant, anywhere, and on-demand transmission of electricity. This technology has been widely applied in many scenarios, especially on the power supply side, and it can effectively smooth the output fluctuations of new energy.

With the large-scale integration of distributed wind and photovoltaic power into the distribution network, the instability of their output has brought significant impact to the power grid, while also increasing the complexity of distribution network transformation and management. However, the emergence of mobile energy storage technology has provided a new solution to this problem. It can monitor and respond in real-time to changes in the output of new energy, ensure stable power supply through intelligent regulation, and effectively reduce the impact of new energy integration on the power grid.

Mobile energy storage power stations can play a key role in addressing the issue of fluctuations in new energy electricity. On the power side, it can effectively alleviate the fluctuations of new energy electricity, thereby enhancing the regulation capability of the power grid. Meanwhile, by intelligently managing the energy output of clean energy systems, mobile energy storage power stations can avoid resource waste. In addition, facing the challenge of uneven geographical distribution of renewable energy supply and demand, its strong flexibility and adaptability make mobile energy storage stations more outstanding than fixed energy storage, providing strong support for the widespread consumption of clean energy.

On the grid side, mobile energy storage stations also play an indispensable role. It can participate in peak shaving and frequency regulation of the power system by flexibly adjusting the charging and discharging power, and meet temporary power supply needs in special situations such as equipment and line maintenance, power system failures, etc. In addition, energy storage stations can also provide reactive power balancing services to the power system, ensuring voltage stability of the power system.

Categories and product types of power auxiliary services

With the gradual improvement of the electricity spot market, the benefits obtained by energy storage technology through providing electricity auxiliary services will gradually surpass peak valley price arbitrage and become the main source of profit. It is predicted that by 2025 and 2030, the total electricity consumption in China will reach 9.5 trillion kilowatt hours and 11 trillion kilowatt hours respectively. Assuming the national average selling electricity price is 0.6 yuan/kilowatt and the ancillary service fee accounts for 3% of the total electricity consumption in society, the ancillary service market size at these two time points will reach 171 billion yuan and 198 billion yuan, respectively.

In terms of participating in the peak shaving auxiliary service market, mobile energy storage power stations have a competitive advantage over fixed energy storage due to their flexible deployment and rapid response characteristics. In addition, mobile energy storage stations can also achieve electricity cost management and demand side response on the user side, thereby bringing more added value to users.

In the electricity market, mobile energy storage technology has demonstrated its unique advantages. It can flexibly schedule and adapt to microgrid systems or ordinary distribution network systems, and can easily expand or reduce capacity according to demand, thereby helping industrial and commercial users achieve efficient and cost-effective electricity management. In addition, mobile energy storage vehicles equipped with charging modules can be used as small charging stations, providing trial operation support for the site selection of charging and swapping stations, and valuable data support for the rational layout of charging and swapping stations. Meanwhile, mobile energy storage also provides strong support for outdoor emergency support and rescue.
With the continuous growth of social electricity demand, the large-scale integration of renewable energy, and the continuous improvement of electricity spot and auxiliary service markets, mobile energy storage stations are gradually becoming an efficient and convenient way of energy transmission. Its commercialization prospects are becoming increasingly clear, bringing new development opportunities to the field of new energy. Green Power Intelligent Alliance is committed to the development strategy of new energy and green power transportation, and will continue to promote the research and application of the integrated project of "wind solar hydrogen storage vehicles". We firmly believe that by widely promoting the demonstration projects of "new energy+energy storage" and creating innovative mobile energy replenishment services, we will effectively promote the low-carbon, safe, and efficient utilization of clean energy, injecting strong impetus into sustainable development.
