SSC's Energy Storage Solution Provides Optimal Solution to the Problem of Connecting a High Percentage of New Energy to the Power System

In the process of transforming the global energy structure to cleaner and lower carbon, the proportion of new energy sources such as wind and solar in the power system continues to rise. However, the high proportion of new energy access also brings a series of problems, such as power grid fluctuations caused by intermittent power generation, insufficient consumption capacity, and declining stability. In the face of these challenges, the SSC energy storage solution launched by Henan Saimei Technology Co., Ltd (ISEMI) has become the optimal solution for cracking the problem of high-percentage new energy access by virtue of the flexible combination of supercapacitors, lithium titanate batteries, LFP batteries, and other core products, and is widely used in the fields of secondary frequency regulation, shared energy storage, second-level UPS backup, heavy truck startup, and wind power energy storage.

A high proportion of new energy access to the core of the problem

With the rapid growth of new energy installed capacity, its inherent intermittency and volatility of the impact on the power grid is increasingly prominent. On the one hand, wind and solar power generation is significantly affected by the weather, the output power is high and low, resulting in increased frequency and voltage fluctuations in the grid, threatening the stable operation of the power system; on the other hand, new energy generation of centralized and distributed coexistence, so that power consumption is under enormous pressure, abandoned wind, abandoned light phenomenon occurs from time to time, resulting in energy waste. In addition, the limitations of traditional energy storage systems in terms of response speed, cycle life, cost control, etc., are also difficult to meet the complex needs of a high proportion of new energy access.

SSC energy storage program: the optimal solution of multi-technology integration

Henan Saimei Technology's SSC energy storage program takes “flexible adaptation, efficient synergy” as the core, and combines supercapacitors, lithium titanate batteries, LFP batteries and other products scientifically, so that they can be assembled individually to give full play to the advantages of a single product, and can be mixed devices to realize complementary performance. It can be assembled individually to give full play to the advantages of a single product, and can also be mixed to realize complementary performance, and can respond to the problem of accessing a high proportion of new energy in all aspects. (I) Supercapacitor: Extremely Fast Response, Stable Control of Grid Frequency.

Supercapacitor, as the “speed bearer” of SSC energy storage program, has millisecond charging and discharging response capability and ultra-high power density. In the secondary frequency regulation scenario, when the new energy generation fluctuation triggers the grid frequency shift, supercapacitor can instantly release or absorb the electric energy, quickly suppress the frequency fluctuation, and ensure the stability of the grid. For example, in wind power storage projects, supercapacitors can respond to power fluctuations caused by changes in wind speed in real time, so that wind power can be smoothly connected to the grid, significantly increasing the rate of wind power consumption. At the same time, the cycle life of supercapacitors up to hundreds of thousands of times, can be involved in high-frequency frequency regulation, reduce long-term operating costs. (ii) Lithium Titanate Battery: Safe and Long-lasting, Guaranteeing Continuous Power Supply.

Lithium titanate battery is known for its high safety, wide temperature range adaptability and ultra-long cycle life, and it is the “stable cornerstone” in the SSC energy storage program. In the shared energy storage project, lithium titanate battery can be used as the core of energy reserve, operating in synergy with new energy power station, storing excess electricity in the trough of electricity consumption and releasing it in the peak of electricity consumption, realizing peak shaving and valley filling, and improving the ability of new energy consumption. Its excellent performance in low-temperature environments also makes it an ideal choice for wind power and photovoltaic energy storage in cold regions, ensuring the reliable operation of energy storage systems in extreme weather. (C) LFP battery: high capacity and high efficiency, optimizing energy allocation.

LFP battery (lithium iron phosphate battery) has high energy density and obvious cost advantages, and bears the heavy responsibility of large-scale energy storage in SSC energy storage solutions. In the distributed new energy storage system, LFP batteries can be used in conjunction with solar batteries to efficiently store photovoltaic power to meet the self-consumption needs of households, industrial and commercial users, and to reduce the dependence on the power grid. In the field of heavy-duty truck starting, the hybrid device of LFP battery and supercapacitor can provide strong starting power for heavy-duty trucks, and at the same time, utilize new energy power generation for charging, which promotes the low-carbon transformation of the transportation field.

Third, multiple scenarios on the ground to witness the strength of the program

(a) Secondary frequency regulation: guarding the stability of the power grid

SSC energy storage program through the hybrid configuration of supercapacitors and lithium titanate batteries, in the new energy accounted for more than 50% of the regional power grid, the frequency deviation is controlled within ±0.1Hz, the response speed is more than 3 times higher than the traditional program. The response speed is more than 3 times higher than the traditional solution, which significantly reduces the cost of grid regulation.

(II) Shared Energy Storage: Enhancing Resource Utilization

In a provincial shared energy storage demonstration project, the SSC energy storage solution integrates LFP batteries and supercapacitors, realizing an energy storage capacity of 100MW/200MWh, increasing the rate of new energy consumption to 98%, and reducing the amount of abandoned wind and light by more than 100 million kilowatt-hours per year.

(III) Second-level UPS power backup: safeguarding key facilities

In data centers and other scenarios requiring high power continuity, the supercapacitor separate system in the SSC energy storage solution can switch power supply within 0.1 seconds of utility power interruption, and with the continuous endurance of lithium titanate batteries, it ensures uninterrupted operation of servers and other key equipments, and provides a “last line of defense” for the stable operation of new energy power grids. “last line of defense” for the stable operation of the new energy grid.
