　　 In the photovoltaic system, when the power of the photovoltaic system is greater than the power of the local load, the excess electricity that cannot be consumed needs to be sent to the grid. Due to the flow direction of this energy being photovoltaic module inverter → load → grid, which is different from the current direction of the grid system, it is called "reverse flow". Anti backflow protection device is a power protection technology mainly used to prevent backflow in the power system to protect the safety of equipment and systems. Usually, an anti backflow device is installed on the AC side to monitor the current flow and control the DC end of the photovoltaic inverter for power generation. When current is detected flowing into the grid, the anti backflow device feeds back the detected grid access point data to the inverter, which quickly responds and dynamically adjusts the output power of the inverter to achieve zero power grid connection

　　Introduction to energy storage project? With the transformation of the global energy structure and the rapid development of renewable energy, energy storage technology has gradually become a key link in regulating energy supply and demand, and improving energy utilization efficiency. Against this backdrop, distributed energy storage systems have emerged as an effective means of addressing energy instability and volatility. Distributed energy storage, with the help of miniaturized and modular energy storage devices, can store and release energy at the user end, thereby achieving flexible regulation of local power grids. This system can not only effectively balance the intermittency and instability of renewable energy sources (such as solar and wind energy) in the power generation process, but also provide reliable power support during peak demand periods, reducing the pressure on the power grid. This article introduces the application of the Acrel-1000DP distributed energy storage monitoring system by Ankerui in the 5MW distributed energy storage project of Jinyi Industrial in Jiaxing, Zhejiang. The system optimizes the energy management of the enterprise, effectively reduces power costs, and ensures the continuity and stability of production activities.

　　 Due to the small number of solar panels in the balcony photovoltaic power station and limited sunlight exposure, the electricity generated by the panels on the balcony will be limited. Here are some suggestions for optimizing power generation.Energy storage metering, electric energy meter, reverse flow monitoring instrument

　　In the power system, power is generally transmitted from distribution transformers to various loads in the grid, which is called forward current. After installing a household solar power station, when the power of the photovoltaic system is greater than the power of the local load, the excess electricity that cannot be consumed needs to be sent to the grid. Due to the different direction of current from conventional methods, it is called reverse flow. Non reversible photovoltaic system refers to a photovoltaic system whose power generation is always less than or equal to the load's electricity consumption. When the power generation is insufficient, it is powered by the power grid, that is, the photovoltaic system and the power grid are connected together to supply power to the load.

　　When photovoltaic inverters convert the direct current generated by photovoltaic modules into alternating current, there will be DC components and harmonics mixed in; At the same time, there is a situation where the remaining photovoltaic power cannot be dispatched to the power grid through distribution transformers. So, currently some power departments only allow photovoltaic systems to be integrated into the city power grid, but do not allow surplus electricity to be fed into the large power grid through distribution transformers. The anti backflow device is designed to solve such problems.
