The method comprises the following steps: S1, acquiring photovoltaic signal data and performing calculation; s2, calculating energy storage capacity data, and selecting a corresponding working scene mode according to the photovoltaic signal data and the energy storage capacity data in the S1; s3, controlling the optical storage and the power grid to perform cooperative power supply according to the working mode; the system comprises a photovoltaic unit, the photovoltaic unit is connected with an energy storage unit and a monitoring unit, the energy storage unit is respectively connected with a control unit and an output power monitoring unit, the output power monitoring unit is connected with a scene mode selection unit, and the scene mode selection unit is respectively connected with the control unit, a power grid and a load. According to the real-time condition of photovoltaic output and the residual condition of stored energy, by calculating and analyzing related data of light storage, different working scene modes are selected to supply power to the load, the intermittency and randomness of light storage are overcome, and the stability of photovoltaic power supply is improved.

Description

technical field [0001] The present invention relates to the field of power supply control, in particular to a multi-scenario optical-storage collaborative control method and system. Background technique [0002] In recent years, photovoltaic power generation has been widely used due to its clean, non-polluting and sustainable advantages. However, photovoltaic output has certain intermittent and random characteristics, and it is very unstable when supplying power to loads. If it directly supplies power to loads, it will give The stable operation of the power system brings great challenges. How to effectively stabilize the fluctuation of photovoltaic output and improve the stability of photovoltaic storage has become an urgent problem to be solved for the large-scale development of photovoltaic power plants. [0003] At present, the existing technologies are generally aimed at improving the power distribution and control accuracy of optical storage. For example, a "a distribu...
