Integrated Reserve, New Force in Low Carbon Parks
New energy storage is of great significance in promoting the consumption of renewable energy and building a new type of power system. However, facing the vast market demand, the energy storage industry still faces problems such as cost disturbances, profitability difficulties, and safety constraints.
The 14th Five Year Plan period is a crucial period for China to build new energy storage, which is of great significance in promoting the consumption of renewable energy and building a new power system. Since the proposal of the "dual carbon" goal, China's energy storage industry has undergone earth shaking changes, with further development in policy support, technological routes, and other aspects. However, facing the vast market demand, the energy storage industry still faces problems such as cost disturbances, profitability difficulties, and safety constraints.
On December 27th, the Energy Storage Application Branch of the China Chemical and Physical Power Industry Association and Vertiv (NYSE: VRT) jointly hosted the "New Forces in Low Carbon Parks with Integrated Energy Storage" live broadcast event. From the dimensions of energy storage development status, technological route, and energy storage security, the application value of the "Integrated Energy Storage" plan was discussed, providing new ideas for the development of low-carbon parks with energy storage.
How to make a profit
Realistic problems faced by user side energy storage
Mr. Liu Yong, Secretary General of the Energy Storage Application Branch of the China Chemical and Physical Power Industry Association and CEO of China Energy Storage Network, believes that in the rapid growth of the energy storage market, user side energy storage will become one of the important application markets.
According to Mr. Liu Wenfeng, Technical Director of the Smart Energy Business Unit of Shenzhen Power Grid Smart Energy Technology Co., Ltd., user side energy storage can help users achieve functions such as peak shaving and valley filling, demand management, and backup power supply. In the future, it will also participate in demand response, spot market, and auxiliary service markets in the form of virtual power plants.
However, from the current project practice, the only model that can truly bring profits is peak valley arbitrage, and the core of profitability lies in the peak valley price difference and energy storage costs. Mr. Liu believes that in this situation, the future development of user side energy storage should focus on the comprehensive needs of power users in the park, using energy storage as a starting point to provide users with a package of electricity solutions.
Integrated Reserve
A New Energy Storage Model for Low Carbon Parks
Based on the optimistic long-term trend of the energy storage industry, Vertiv Technology conducted detailed market research and technical analysis, and persisted in completing the construction of the Jiangmen factory energy storage project, providing practical experience to meet the energy storage needs of the park.
Mr. Yi Xufu, Director of Market Research and Product Management at Vertiv China, introduced that over 15000 square meters of solar panels have been installed in the Jiangmen factory of Vertiv's energy storage project, and an 800KW/1.6MWH energy storage system has been installed to absorb photovoltaic power generation. At the same time, the Jiangmen factory also took into account short-term fluctuations, power outages, and power restrictions in the power grid, and used the lithium battery energy storage system as a backup power source to ensure the continuous operation of key businesses.
The energy storage system of Jiangmen Factory has achieved both the storage of renewable energy and the backup of critical power without interruption, successfully implementing the concept of "integrated storage".
In operation, Vertiv's Jiangmen factory reserve integration system fully utilizes the peak valley price difference policy and participates in the demand side response of the power grid, achieving sustained returns during the operation phase.
According to calculations, based on the rational and effective use of strategies, the integrated reserve plan can achieve investment returns in 3-6 years. Compared to traditional energy storage and separate uninterrupted power supply systems, this solution undoubtedly has better investment cost-effectiveness.
Moreover, for users with special needs for power quality, the construction of an integrated reserve system through investors can, on the one hand, solve power quality problems for users free of charge; On the other hand, investment returns can be obtained through normalized peak shaving and valley filling, ultimately forming a win-win situation.
safety protection
The bottom line for the development of energy storage industry
Vertiv technology solves the problem of thermal runaway by constructing a three-dimensional protection system that integrates battery body safety, AI monitoring, and fire protection. From the very early stage of fault detection, early control is implemented and more effective fire protection measures are implemented according to the situation, truly reducing the risk of fire and explosion caused by thermal runaway and meeting the safety requirements of users for energy storage systems.
Mr. Fu Liehu, Director of the Design Department of the Data Center at Vertiv China, mentioned that Vertiv has achieved four levels of protection in the overall safety design of the Jiangmen factory energy storage power station, including early gas detection, fire alarm, gas extinguishing, and secondary spraying.
The safety concept of Vertiv Technology is "prevention first, fire protection secondary", and this concept is implemented through energy storage safety management software.
Design concept of energy storage nest
Virtual construction reliable landing energy storage scheme
The operation effect of energy storage power stations needs to reach the design value, and the early planning and design as well as various simulation simulations are crucial.
Simply put, there are two dimensions to achieving the design value: one is meeting the energy storage efficiency standard, and the other is the sustainability of system operation. In the early construction stage, we will seek the optimal layout through digital and virtualization technologies, and pay more attention to daily operation and maintenance in the later stage.
In the construction of energy storage power stations, Vertiv technology uses BIM+technology and digital and virtualization methods to build a 3D "energy storage nest", simulate various possibilities of engineering productization, and simulate the temperature field through CFD simulation, creating a safe and reliable charging and discharging environment for lithium batteries.
Practice has proven that based on BIM+technology, infinite zero cost simulations can be conducted on the integration sequence and integration process of energy storage power plants to find the best integration solution, thereby making the reserve integration solution infinitely close to the design value.
User side energy storage mainly provides users with functions such as peak shaving and valley filling, demand management, backup power supply, and integrated operation of optical and storage in a market-oriented manner. In the future high proportion renewable energy power system, user side energy storage peak valley arbitrage (including spot market arbitrage), integrated photovoltaic storage, and integration with microgrids will be the main application scenarios.
Currently, new energy storage has important value and key significance in building new energy systems, promoting large-scale development of renewable energy, achieving carbon peak and carbon neutrality goals, and ensuring the safe and stable operation of new power systems.
