Problems solved by technology

[0002] With the rapid growth of electricity demand, some areas have difficulty in using electricity. In order to solve the problem of electricity consumption, some areas have adopted a unified establishment of small photovoltaic power stations to solve the problem of electricity consumption, making full use of the renewable characteristics of solar energy. Power generation has the advantages of being clean, environmentally friendly, and renewable. However, there is a lack of reliable management for the photovoltaic system. When there is a problem with the photovoltaic system, the operation of the entire photovoltaic system will be in a paralyzed state, unable to provide users with power, which will affect the normal operation of users. life, which brings great inconvenience to the user's life and reduces the user experience

Embodiment 1

[0027] Example 1: as figure 1 As shown, the photovoltaic control system includes an energy storage module, a power dispatching module and a server;

[0028] The energy storage module is used to plan and store the electrical energy converted by the solar energy device. With the rapid growth of electricity demand, some areas have difficulty in using electricity. In order to solve the problem of difficult electricity consumption, some areas adopt the unified establishment of small photovoltaic power stations In order to ensure the electricity demand of users, a reasonable energy storage method is needed to avoid the problem that the stored electricity cannot meet the electricity demand of users due to special circumstances;

[0029] Specific methods include:

[0030] Obtain the electricity consumption area, which is the user area that uses the same small photovoltaic power station, and number the electricity consumption area, collect the total daily average electricity consumpti...

Embodiment 2

[0043] Embodiment 2: A photovoltaic control method is provided, which is applied to the photovoltaic control system of any one of the above, and the specific control method includes:

[0044] Step 1: Set up a power consumption area, store the electric energy converted by the solar device in the daily energy storage unit, the backup energy storage unit and the dispatching energy storage unit, set the daily energy storage unit as the first energy storage priority, and store the backup energy storage unit. The unit is set to the second energy storage priority, the dispatching energy storage unit is set to the third energy storage priority, and the daily energy storage unit and the standby energy storage unit have an energy storage upper limit;

[0045] Step 2: Set a backup warning line and a dispatching line in the backup energy storage unit, and the backup warning line is lower than the dispatching line; perform electric energy dispatching in the power consumption area according ...

Abstract

The invention discloses a photovoltaic control system and method, belonging to the technical field of small photovoltaic power plants, comprising an energy storage module, an electricity dispatching module and a server; the energy storage module is used for planning and storing electric energy converted by a solar device, obtaining electricity consumption areas, and Number the electricity consumption area, collect the total daily average electricity consumption of users in the electricity consumption area, mark it as electricity consumption of the area, set the backup energy storage unit, dispatch energy storage unit and daily energy storage unit, the backup energy storage unit There is a backup warning line inside. When the electric energy stored in the backup energy storage unit is lower than the backup warning line, an electricity consumption alarm signal is generated, and the electricity consumption alarm signal and the corresponding electricity consumption area number are sent to the electricity consumption scheduling module; The dispatching module dispatches the electric energy in the dispatching energy storage unit, and realizes the electric energy dispatching in the area through the mutual cooperation of the energy storage module and the electricity dispatching module, so as to avoid affecting the daily life of users.
