This paper mainly focuses on the modeling and grid-connected stability of large-scale clustered lithium-ion battery energy storage power stations. The large-capacity lithium-ion battery system and PCS in the energy storage power station are modeled.
With the large-scale integration of renewable energy into the grid, its randomness and intermittent characteristics will adversely affect the voltage, frequency, etc. of the new power system, and even cause partial system collapse. However, the above problems can be solved by configuring large-scale clustered energy storage in the new power system.
The large-scale lithium-ion battery energy storage system is composed of N modular battery energy storage subsystems (BESS for short) in parallel.
This paper discusses the current research status of the energy storage power station modeling and grid connection stability, and proposes the structure of the digital mirroring system of large-scale clustered energy storage power stations.
Abstract: High penetration of renewable energy resources in the power system results in various new challenges for power system operators. One of the promising solutions to sustain the quality and reliability of the power system is the integration of energy storage systems (ESSs).
Battery energy storage systems provide multifarious applications in the power grid. BESS synergizes widely with energy production, consumption & storage components. An up-to-date overview of BESS grid services is provided for the last 10 years. Indicators are proposed to describe long-term battery grid service usage patterns.
