Abstract
The large-scale battery energy storage scatted accessing to distribution power grid is difficult to manage, which is difficult to make full use of its fast response ability in peak shaving and frequency modulation. With the rapid development of 5G and cloud technology, it is possible to realize interconnection of distributed battery energy storage system (BESS), cloud integration of energy storage system (ESS) and data edge computing. In this paper, a BESS integration and monitoring method based on 5G and cloud technology is proposed, containing the system overall architecture, 5G key technology points, system margin calculation. Therefore, rapid, accurate and flexible control of BESS can be realized, which make more use of BESS in peak shaving and shifting, new energy consumption, electric power bidding platform and other fields.
Highlights
In recent years, with the continuous increasing number of distributed energy storage system (DESS), the proportion of energy storage power station in the power grid gradually increases [1], and the amount of data generated by the power station operation is very large
Due to the current situation that ESS's decentralized access to the distribution network, the data transmission delay of the communication mode is large, so it is difficult to do centralized control of ESS and to make full use of its advantages of rapid response. 5G technology is mainly applied in 3 scenarios including Enhanced Mobile Broadband, ultra-reliable and Low Latency Communication and Massive Machine Type Communication [2,3,4]. 5G is suitable for automatic driving, industrial control and other occasions requiring less time delay and higher communication reliability
A battery energy storage system (BESS) integration and monitoring method based on 5G and cloud technology is proposed
Summary
With the continuous increasing number of distributed energy storage system (DESS), the proportion of energy storage power station in the power grid gradually increases [1], and the amount of data generated by the power station operation is very large. Due to the current situation that ESS's decentralized access to the distribution network, the data transmission delay of the communication mode is large, so it is difficult to do centralized control of ESS and to make full use of its advantages of rapid response. With the aid of 5G technology to the advantage of mMTC, a large amount of data, such as battery voltage, battery current, temperature and SOC, collected by the BESS, can be rapidly transmitted through 5G technology, and the control orders of power station can be issued quickly. It is helpful to realize reducing information transmission delay, centralized management of DESS, and do rapid response to dispatching command of grid. The BESS integration and monitoring method based on 5G and cloud technology is
