Description

TECHNICAL FIELD

[0002] With the development of new energy technology, distributed photovoltaic has been widely popularized, and has become an important force to promote energy transformation and achieve the "double carbon" goal. In recent years, household distributed photovoltaic installations have experienced explosive growth, with 8.91 GW of new household distributed photovoltaic installations added in the first half of 2023, a year-on-year increase of 51.5%. As of the end of 2023, the total installed capacity of distributed photovoltaic has reached 42% of the total installed capacity of photovoltaic. Distributed photovoltaic has become one of the important driving forces for global energy structure transformation.

[0003] Since most distributed photovoltaic systems use the "self-generation and self-use, excess power on-grid" mode, the reverse active power of the State Grid metering meter only records the excess power on-grid power, and cannot effectively track the actual photovoltaic power generation. Distributed photovoltaic investors or users generally set up a metering-grade electric energy meter at the photovoltaic grid-connected point to count photovoltaic power generation:

[0004] User consumption power = photovoltaic power generation - excess power on-grid power;

[0005] Since distributed photovoltaic systems are mainly distributed on building rooftops, agricultural facilities, abandoned land, and parking lot canopies, compared to the centralized management of centralized photovoltaic systems, distributed photovoltaic systems are more difficult to manage. Since distributed photovoltaic systems are small in size and widely distributed, users have difficulty effectively monitoring them, and most related data collection is achieved through manual inspection and meter reading.

[0006] Distributed photovoltaic systems are generally managed through manual inspection, and when photovoltaic panels are damaged or malfunctioning, it is difficult to detect them in a timely manner, which can result in reduced power generation or even serious electrical accidents such as electrical fires. Therefore, more and more distributed photovoltaic systems have begun to install cameras for video surveillance. Cameras are equipped with 4G / 5G Internet of Things cards, and video data is uploaded to the background monitoring software through wireless means. In some large distributed photovoltaic sites, several or dozens of cameras may be needed to achieve comprehensive coverage. Each camera requires the installation of an Internet of Things card, which is difficult to manage and expensive, and cannot achieve centralized management of video.
