Photovoltaic grid-connected power generation system

In photovoltaic power stations, photovoltaic smart meters have a special role, which is to record reverse “power generation”. Why should we record such a reverse power situation? This article will analyze this problem for you and reveal the mystery behind reverse electricity.

  1. Definition of reverse electricity:
    Reverse power refers to the power that is returned to the grid through the photovoltaic smart meter when the power generated by the solar cell exceeds the demand. That is to say, if the power generation capacity of the photovoltaic power generation system exceeds the load requirements, the remaining power will It will be transmitted to the power grid by the photovoltaic meter, which is like a “power generation” process. At this time, the power recorded by the photovoltaic meter is called “reverse power”.
  2. Principle of reverse electricity:
    Photovoltaic cells convert light energy into electrical energy. Normally, photovoltaic cells will give priority to providing load demand and converting generated electricity into electrical energy. When the power generation of photovoltaic cells exceeds the load, the remaining power will be sent back to the grid through the photovoltaic smart meter under the action of the inverter and fed back to the grid.
  3. The meaning of reverse electricity:
    The emergence of reverse charge is of great significance. First, it can maximize the use of photovoltaic power generation capacity and avoid the waste of excess power. Secondly, photovoltaic power stations transmit power to the grid through reverse power, which can provide additional power support for the grid and reduce the load on the grid. In addition, reverse power can be used to recover excess power at a certain price through a settlement mechanism, bringing economic benefits to photovoltaic power station operators.
  4. Data statistics and analysis of reverse electricity:
    In order to count and analyze reverse power data, photovoltaic smart meters usually have multiple functions. First of all, the output power of photovoltaic cells can be displayed in real time, including forward and reverse power. Secondly, the photovoltaic smart meter can record the accumulated power generation in two forms: forward and reverse. It is helpful for users to understand the power generation efficiency and power supply status of photovoltaic power generation.

Summarize:
Reverse power refers to the remaining power fed back to the grid by the photovoltaic smart meter when the photovoltaic power generation exceeds the load. This is of great significance for giving full play to the power generation capacity of photovoltaic power stations, providing more electric energy to the grid, and bringing more economic benefits to it. Through statistics and analysis of data collected by photovoltaic meters, the performance and power supply status of photovoltaic power stations can be known.

The proposal of reverse power generation is not only a manifestation of the high efficiency of photovoltaic power generation systems, but also a unique charm of new energy development. Through the recording and analysis of photovoltaic meters, we can deepen our understanding and utilization of new energy and promote sustainable development. We believe that with the development of science and technology, the observation and evaluation of reverse current by photovoltaic smart meters will become more and more accurate, allowing people to have a deeper understanding of reverse current.
