5G technology helps the State Grid distributed photovoltaic cloud network make a new leap

A few days ago, with the pop-up of the prompt window of "data transmission protocol parsing successful", the distributed photovoltaic poverty alleviation power station in Nanguoxia Village, Laishui County, Hebei Province officially realized the full opening of the 5G communication link, and countless unstructured data recording the power generation, power, conversion rate and other information of the power station were remotely transmitted to the State Grid distributed photovoltaic cloud network master station at a speed of 10G per second, and 5G technology was successfully trialed
in the photovoltaic cloud network.
This is the first application of 5G technology in the field of energy Internet on a global scale, and it also indicates that a new era of comprehensive acceleration and intelligent interconnection in China is coming

State Grid photovoltaic cloud network operation and maintenance monitoring platform

The biggest change brought by 5G technology to the photovoltaic cloud network is the significant improvement
of data transmission rate and quality.
According to reports, the previous data transmission of the State Grid distributed photovoltaic cloud network, mainly relying on optical fiber communication mode, the inverter and energy meter data collected by the data acquisition terminal are remotely transmitted back to the photovoltaic cloud network main station, which has a relatively low transmission rate and limited bandwidth, and it is difficult to realize the timely transmission, processing and display of unstructured data such as on-site video data, audio data and image recognition data of distributed photovoltaic power plants, which limits the efficiency of
distributed photovoltaic remote diagnosis, operation and maintenance and maintenance work 。 Through the application of 5G communication technology, the data channel of photovoltaic power plants is effectively expanded, and mobile phones, PAD, and integrated energy service "multi-table in one" data collection terminals can achieve high-speed, safe and reliable remote real-time interconnection with the photovoltaic cloud network main station, which provides a broad imagination space for future distributed photovoltaic power plants to interconnect in a more intelligent and efficient way, and users to participate in the construction and operation of photovoltaic power plants more conveniently and
actively.

State Grid Distributed Photovoltaic Cloud Network is the largest distributed photovoltaic one-stop shared service platform in China, and it is also one of the important measures of the State Grid Corporation to implement the requirements of national energy transformation and serve the
development of energy transformation.
By the end of February this year, the platform had been connected to 873,800 distributed users and had an installed capacity of 34.
91 million kilowatts
.

In recent years, with the rapid development of distributed photovoltaics, the massive information collection, field device monitoring, remote diagnosis and operation and maintenance of photovoltaic power plants and other services have put forward higher requirements
for communication network transmission capabilities.

Xie Xiangying, head of the photovoltaic cloud business department of the State Grid E-commerce Company, introduced that 5G communication has the characteristics of high speed, high security, full coverage and intelligence, which can effectively solve the pain points of distributed photovoltaic power plants such as scattered, many points
and large volume 。 State Grid E-commerce Company attaches great importance to the research and application of 5G technology in photovoltaic cloud network, and Beijing University of Posts and Telecommunications established a joint laboratory to promote the joint application research and development of 5G technology, the first successful application of 5G technology in photovoltaic cloud network, to meet the future photovoltaic cloud network wider data and business efficient interconnection needs, will help to integrate the whole photovoltaic industry chain resources, enhance the participation of the whole society of the photovoltaic industry, and create an open and shared distributed photovoltaic industry new format.
Promote the implementation of the comprehensive energy service strategy of the State Grid and the healthy and rapid development of
national clean energy.

Professor Wen Xiangming, senior consultant of the 5G project team of State Grid distributed photovoltaic cloud network and vice president of Beijing University of Posts and Telecommunications, introduced that the open source 5G system of photovoltaic cloud network application can support 10Gbps peak access rate, million-level connection density and millisecond-level end-to-end delay, which can effectively solve the problems
faced by photovoltaic cloud network such as the surge in the number of users, the difficulty of collecting massive distributed data, and the difficulty of ensuring wide-area coverage 。 In addition, 5G slicing technology can provide isolated and exclusive network slices for different attribute services such as PV cloud network data collection, operation monitoring, and electricity bill settlement, ensuring the differentiated needs and service quality of different services, and ensuring that PV cloud networks are more efficient, safe and reliable to achieve personalized and intelligent comprehensive services
