INPOWER smart storage centralized PCS: Multi-scenario enabling, ushering in a new era of energy storage

In the wave of Energy Revolution, energy storage technology, as a key support, is gradually becoming the focus of global attention. INPOWER smart storage, as a leader in the field of energy storage, in addition to the string PCS, its centralized energy storage converter (PCS) with excellent performance and wide applicability, it also stands out in a variety of complex application scenarios such as high altitude, low temperature, multiple off-grid parallel machines, network construction, and energy storage test platform, which provides a solid guarantee for the efficient and stable operation of the energy storage system.

High altitude scene: Fearless Challenge, stable operation

In the high altitude area, the air is thin, the temperature is low, and the ultraviolet ray is strong, which puts forward extremely high requirements for the performance and reliability of power equipment. INPOWER's centralized PCS are specially designed and optimized for high-altitude environments. The advanced heat dissipation technology effectively solves the problem of heat dissipation in high altitude area, and ensures the stable operation of the equipment in high temperature difference environment. At the same time, by strengthening the electrical insulation performance, the safety and reliability of the equipment in low pressure environment are improved.

In Qamdo, Xizang's 4,200-metre high-altitude photovoltaic power station, INPOWER PCS is tasked with peaking and frequency regulation, as well as power curtailment. Facing the harsh natural environment, the PCS device has achieved long-term stable operation with excellent performance, providing strong support for the stable power supply of the local power grid, iNBAU has proven the technical reliability and stability of the PCS at extremely high altitudes.

Low temperature scene: cold and frost resistance, continuous and efficient

The low temperature environment will have a significant impact on the performance and life of the battery, and also test the low temperature adaptability of the energy storage converter. INPOWER central PCS are equipped with efficient heating and insulation devices that can quickly raise the temperature of the equipment in a low-temperature environment to ensure normal start-up and operation of the equipment. In addition, by optimizing the circuit design and control algorithm, the influence of low temperature on the performance of the equipment is reduced, and the charging and discharging efficiency and life of the battery are improved.

In Nen River, Heilongjiang, winter temperatures often drop below -40 c. INPOWER's 40MW wind, solar and solar energy storage project in the area has performed well, providing a reliable solution for local energy storage and utilization, even in extremely cold conditions, the normal electricity demand of residents and enterprises is guaranteed.

Multiple off-grid parallel machine scenario: cooperative operation, reliable power supply

In some remote areas or power consumption scenarios with high requirements for power supply reliability, the demand for off-grid parallel operation of multiple energy storage converters is increasing. INPOWER smart storage centralized PCS have advanced off-grid parallel control technology, which can achieve precise synchronization and power sharing between multiple devices, and effectively improve the reliability and stability of the system.

Due to the special geographical location, it is difficult to cover the power grid in the projects of oil field storage in Gansu province, mining area storage in Xinjiang province and many MW-level microgrid projects, INPOWER intelligent storage provides a solution for multiple centralized PCS off-grid integration. These PCS work together to provide a reliable power supply to households and businesses, meeting their daily electricity needs and increasing their energy self-sufficiency.

Network construction scenario: active support to ensure grid resilience

With the increasing proportion of new energy power generation, the power grid presents the characteristics of"Weak inertia and low damping", which puts forward an urgent demand for the network construction ability of energy storage converters. INPOWER centralized PCS equipped with virtual synchronous generator (VSG) technology can simulate the inertia and damping characteristics of traditional synchronous generators, actively provide voltage and frequency support for the power grid, and effectively improve the stability of the power grid. At the same time, the PCS has the ability of fast power regulation, which can respond in milliseconds and output compensation power to suppress the abnormal fluctuation of power grid parameters under the emergency conditions such as frequency fluctuation and voltage sag.

INPOWER smart storage not only participates in the preparation of the network group bid, but also performs well in many network construction projects. In a new energy-rich industrial park distribution network project, the installed capacity of wind power and photovoltaic in the park accounts for more than 60% , and the traditional power grid is difficult to cope with the impact of new energy output fluctuations. Inbev deploys grid-connected centralized PCS, which use VSG technology to simulate grid inertia and quickly compensate for power gaps in extreme conditions when photovoltaic output plummets by 30% , it ensures the continuous and stable operation of precision manufacturing equipment in the park, while enhancing the ability of the park's distribution network to absorb new energy sources. The new efficient energy use is significantly higher than before.

Energy storage test platform scenario: accurate simulation to assist research and development

Energy storage test platform is an important place to verify the performance and reliability of energy storage system. With its high-precision control performance and rich monitoring functions, INPOWER's centralized PCS can accurately simulate various actual working conditions, which provides strong support for the development and testing of energy storage systems. In the energy storage test platform, INPOWER smart storage PCS can accurately control and monitor the battery charging and discharging process, collect a large amount of data, and provide data basis for the optimization and improvement of the energy storage system.

INPOWER's 5MW and 3.45MW test platforms have been shipped to dozens of integrators and battery manufacturers for in-plant customer product testing. Through the precise control and monitoring of the test platform equipment, researchers can accurately understand the performance of the energy storage system under different working conditions, so as to optimize and improve the energy storage system, greatly shorten the development cycle, improve the efficiency of research and development.

Conclusion:

INPOWER Smart Central PCS with their superior performance and wide range of applications, in high altitude, low temperature, multiple off-grid parallel machine, network energy storage, energy storage test platform and other application scenarios show a strong strength. In the future, inbev smart storage will continue to adhere to the development concept of focusing on the future and taking the lead, continuously improve product performance and technical level, contribute more wisdom and strength to the development of the global energy storage industry, and help the energy transformation, create a green future.
