In the blue sea of new energy storage, the market demand for industrial and commercial energy storage is like an unstoppable tide of the times, becoming a magnificent driving force for the rapid development of new energy storage.
Why industrial and commercial energy storage?
China's industrial and commercial energy storage industry started around 2016, which was the golden stage for the photovoltaic industry to gain momentum and take off. Distributed photovoltaics reached a explosive high point.
In order to ensure the stable output and consumption of new energy, corresponding energy storage systems need to be configured. It is precisely this market demand that has brought new growth points to industrial and commercial energy storage.
At the same time, high energy consuming industrial giants such as petroleum, chemical, metallurgical, electronics, steel, and cement have an increasing demand for energy storage systems in order to achieve energy conservation, emission reduction, and reduce electricity costs.
These enterprises usually have a high electricity load. By configuring energy storage systems and improving power supply reliability, they can maintain production during power rationing periods and ensure that production capacity is not affected.
The soil of the market nourishes the emerging seed of industrial and commercial energy storage. With the rapid germination and spread of this seed, the track of industrial and commercial energy storage has become increasingly crowded, with various participants emerging like mushrooms after rain, mixed with good and bad, competing fiercely.
Faced with fierce competition and complex situations, we cannot help but ponder: how should we protect this emerging soil, ensure its healthy development, and let the ship of industrial and commercial energy storage move steadily forward?
What is the optimal solution for industrial and commercial photovoltaic storage?
The core lies in the product and technology itself
With the continuous decline in upstream raw material prices, the cost of energy storage systems continues to decrease, and the economic performance of industrial and commercial photovoltaic storage systems is also constantly improving. However, even so, economy remains the main factor hindering the healthy and sustainable development of the industry.
In the current investment calculation practice of industrial and commercial photovoltaic storage projects, a significant and undeniable issue is that various non-technical costs are often placed on the edge of calculation, or even completely ignored.
Unlike the calculation method of distributed photovoltaic profit model, the economic calculation model of industrial and commercial energy storage is mainly based on the current time of use electricity pricing mechanism, and we cannot determine whether the time of use electricity pricing mechanism during project construction will continue throughout the entire life cycle of the project.
In addition, after-sales operation and maintenance are also a headache for business owners.
Objectively speaking, the individual size of industrial and commercial energy storage power stations is relatively small and scattered throughout the country, which makes operation and maintenance management more difficult and costly. Compared with the centralized operation and maintenance, centralized commissioning and even the timely response of specialized operation and maintenance personnel of large-scale energy storage projects, the operation and maintenance of industrial and commercial energy storage projects requires more manpower, material resources and financial resources.
From the perspective of the product itself, the technical level of various companies varies greatly. Due to the long operation time of industrial and commercial energy storage systems, it is easy to increase the equipment failure rate.
At present, there is neither a unified product standard system nor a unified quality control standard on the market. Once a fault occurs, troubleshooting and repair will become more difficult, and in more serious cases, it may lead to energy storage safety accidents.
When facing numerous challenges from the external environment and it is difficult to change the situation in the short term, exploring internally has undoubtedly become our wise choice. Industrial and commercial energy storage, as a crucial component of the current energy sector, is facing unprecedented opportunities and challenges. So, in this wave full of variables, what is the breakthrough path for industrial and commercial energy storage?
We firmly believe that the answer should return to the core - the product and technology themselves.
Integrating "DC coupling technology" into products, born for industrial and commercial optical storage
What kind of products and technologies have the right to speak in the industrial and commercial energy storage market? In fact, the core of this issue still lies in reducing costs, increasing efficiency, and creating value for customers.
Taking the recently discussed "DC coupling technology" in the industry as an example, it is an advanced energy storage technology that couples photovoltaic modules, energy storage batteries, and DC charging piles together through a DC bus to achieve efficient energy storage and conversion.
Compared with the AC coupling scheme, the DC coupling scheme requires fewer inverters and can choose energy storage integrated machines, thus having certain advantages in equipment cost and installation cost.
The latest news from the industry is that the industrial and commercial optical storage integration solution that has been launched is based on DC coupling technology.
In industrial and commercial energy storage systems, smoothing mechanisms are particularly important for equipment and sensitive loads that require stable power supply.
Traditional communication coupling systems require independent inverters and multiple conversion steps to adjust power output. If there is a sudden change in power, it will be easier to transmit to the load end, which will affect stability.
The energy storage system of the DC coupled architecture system is directly connected to the photovoltaic system, which can respond quickly, ensure stable output power, and fully avoid the transmission of power mutations to the output end. In this way, the photovoltaic system can provide stable power to the load or grid without affecting the output stability due to short-term changes in lighting.
To ensure the stability of power plant operation while reducing costs and increasing efficiency, it is rare to see such a deep and heavyweight technological layout among those entering the industrial and commercial energy storage track.
Although there is still a phenomenon of household storage products being applied in small commercial and industrial scenarios in the market, this cross-border use has not fully reflected the maximization of cost-effectiveness.
Compared to energy storage solutions designed specifically for industry and commerce, household storage products have shown shortcomings in terms of economies of scale, long-term operation and maintenance costs, and system integration.
