On April 24-26, 2019, the 9th China International Energy Storage Conference was successfully held in Hangzhou. Xi'an Golden Stone Technology Co., Ltd., as the main organizer of the conference, was invited to give a special speech entitled 'Smart Energy Storage Solution for Centralized Control Chain' at the conference.
There are two hot topics in the energy storage industry, namely safety and economy; safety must come first, while also meeting the requirements of stability, durability, and economy; but currently, the key factors in energy storage are safety and economy, which are the core issues that must be addressed. "Mr. Liu Weiwu, Director of Product Solutions at Xi'an Golden Stone Technology Co., Ltd., directly pointed out the main factors affecting safety and economy at the beginning of his speech and proposed the GSSTES centralized control chain intelligent energy storage solution.

The centralized control chain intelligent energy storage solution breaks the traditional PCS overall control scheme, with each battery independently controlled for refined management and control, achieving one-to-one management. Thoroughly solve the problems of traditional energy storage power stations with multiple batteries connected in series, large number of PCS connected batteries, difficult management and control, and single battery failures causing the entire battery stack to be disconnected from the system. Mr. Liu Weiwu mentioned in his speech.
Regarding the centralized control chain solution, Liu Weiwu stated that Golden stone Technology's intelligent energy storage solution for centralized control chain is designed and controlled from three dimensions: integration, control, and chain.
Integration, which integrates the PCS system with BCU, PCU, SCU, and EMS units. BCU is responsible for battery and DC/DC data acquisition and processing; PCU collects AC/DC unit data and uploads it to SCU, and performs logical control according to SCU instructions. SCU communicates with BCU, PCU, electricity meters and other devices to achieve data processing, strategic control and human-computer interaction; At the same time, an EMS system is also integrated internally.

Control mainly refers to intelligent management and control. The EMS integrated within the PCS of the centralized control chain is called Access, which is a device level EMS. It is based on BMS's intelligent management and control of battery charging and discharging, and this function runs through the entire charging and discharging process. When BMS protection fails, it can still ensure the safety and reliability of charging and discharging, such as battery overvoltage, overcharging, BMS failure, upload data not updating or errors. Intelligent control detects abnormal battery and BMS status and actively terminates charging and discharging. Moreover, it has information recording and playback functions, similar to the black box of an energy storage system, which can actively record key data before and after the occurrence of faults for problem localization, analysis, and resolution.

Chain mainly refers to multi-point chains, interconnected sharing, data interconnection, efficient and diverse data transmission, meeting the transmission efficiency requirements for big data control of energy storage power plants. To lay the foundation for adapting to the ubiquitous power Internet of Things, achieving comprehensive knowledge, element interconnection, information sharing, data-driven, and machine learning functions.

Xi'an Golden Stone Electric Technology Co., Ltd., with the mission of providing users with more economical, convenient, and efficient solutions for energy management and application, and the vision of solving the spatiotemporal problems of power production and application, and building an intelligent world of energy interconnection, maximizes customer value through continuous technological innovation, leads the market with high-quality products, promotes the technological upgrading of the energy storage industry, and promotes the rapid development of the industry. ”At the end of the speech, Mr. Liu Weiwu summarized.
