In recent days, extreme high temperatures have led Jiangsu, Zhejiang, Shanghai and other regions into a hot mode, and the hot weather has become particularly fierce after the beginning of autumn, with continuous high-temperature give people all kinds of "roasting tests". The electricity consumption for enterprise production and residents' daily lives has sharply increased, resulting in a rapid growth of the maximum power load, which has set historical highs in many regions. According to data from the National Energy Administration, the national electricity supply and demand situation this summer presents a tight balance across the entire network, with the highest electricity load expected to reach around 130 million kilowatts. In view of the potential power shortage caused by the continuous high temperature weather, the National Energy Administration has planned and carefully deployed in advance to promote the scientific scheduling of various new types of energy storage, so that energy storage power stations can better participate in the interactive regulation of the power grid and ensure the safe and stable operation of the power grid. With the advancement of energy storage technology and the decrease in costs, new types of energy storage have gradually become an emerging force in power system regulation, helping to meet peak summer demand.

1、 Peak shaving and valley filling to optimize power supply

The industrial and commercial energy storage system stores electricity during low demand periods and releases electricity during peak demand periods, especially during the summer peak demand period. The Highstar energy storage system can fully play its key role as a power supply stabilizer. By storing electricity during the midnight off peak period, it is possible to quickly alleviate peak supply and demand conflicts during emergency situations such as daytime and nighttime rush hours.

2、 Flexible configuration, to reduce operating costs

Outdoor cabinets provide protection and environmental adaptability for energy storage equipment, enabling stable operation of energy storage systems in outdoor environments. They can flexibly choose installation locations and adapt to various complex environments in power grid infrastructure construction. The company's outdoor cabinet products integrate battery PACK, liquid cooled PCS, EMS, UPS, liquid cooled units, and multiple functional modules, achieving a highly modular and integrated design that is easy to expand and supports parallel connection of multiple cabinets on the AC side. They also demonstrate greater flexibility in the selection of installation locations and can be quickly deployed to areas close to electrical loads, effectively reducing energy loss during transmission and improving overall energy utilization efficiency. In terms of performance, the product has high power and energy density characteristics, with a maximum PCS efficiency of up to 99%; In terms of cost-effectiveness and safety, a new generation liquid cooled temperature control system has been adopted to achieve efficient heat dissipation, ensuring that the temperature difference of the battery cells is controlled within 3 ℃, significantly extending the system's service life and reducing subsequent operation and maintenance costs. At the same time, the product integrates intelligent active fire protection design, single cluster fine control strategy, and DC side non parallel design, comprehensively improving the safety performance of the product. In addition, the product has excellent protection and environmental adaptability, and can operate stably and reliably in complex and changing outdoor environments, reducing transmission losses and improving energy utilization efficiency.

3、 Intelligent networking, timely and automatic response

On both the power generation and consumption sides, container energy storage systems have a wide range of application scenarios. The Highstar container energy storage system has the characteristics of large capacity, mobility, and high integration. The customized non walk-in container and modular design effectively improve the utilization of cabin space, while reducing the cost of energy storage systems and reducing the project area. In terms of cost and safety, advanced liquid cooling cycle design concepts, intelligent temperature control architecture, intelligent fire pressure relief system, and intelligent energy management and allocation system can achieve effective thermal management in the cabin, safe operation of battery compartments, and precise monitoring of battery cell status, effectively improving system life and safety. On the power generation side, due to the instability and intermittency of solar and wind power generation, when there is excess power generation, container energy storage systems can store the excess electricity and release it when there is insufficient power generation, ensuring a continuous and stable supply of electricity. On the power consumption side, energy storage systems can serve as emergency backup power sources in critical locations such as hospitals, data centers, and communication base stations. In the event of a power outage, they can quickly switch power supply to ensure the normal operation of equipment. For example, in the event of a power failure caused by natural disasters, hospitals rely on energy storage systems to provide continuous power and save lives. In addition, energy storage systems can improve power quality, compensate for voltage fluctuations, harmonics, and protect sensitive equipment.

Industrial and commercial energy storage products, as "urban super power banks", effectively support electricity consumption during peak hours. Compensating for the power supply load gap in the power grid, alleviating the pressure of ensuring supply, and promoting the consumption of new energy, promoting green energy transformation, assisting the high-quality development of the energy industry, and achieving the "dual carbon" goal are of great significance.

Overall, subsidies from the government for the energy storage industry can to some extent increase corporate profits, reduce operating costs, enhance market competitiveness, and promote innovation and progress in the energy storage industry. And with the application of energy storage systems in industrial, commercial, and household users, ordinary users can also use pre stored electricity during peak summer periods to reduce the power load on the grid.

Highstar is committed to being a globally leading provider of efficient energy storage solutions, with years of deep cultivation in the field of new energy.
