Under normal conditions, the afternoon illumination condition is also sufficient, and photovoltaic power generation is preferentially adopted to supply power for loads of electric automobiles and other loads. The operation strategy of the flat period focuses on the charge and discharge of the energy storage system, because the load demand is stable, and when the photovoltaic output is sufficient, the SOC value of the energy storage battery is considered, and then the operation state of the energy storage system is determined. The SOC value may be in a range of 0 to 1, and indicates that the energy storage battery is completely discharged when soc=0 and that the energy storage battery is completely charged when soc=1. Note that the level period exemplified here is 12:00 to 18:00, 23:00 to the next day 00:00 is merely illustrative, and may be specifically set according to practical circumstances, which is not limited in this embodiment.

If the other load power and the charging power of the electric automobile are not larger than the photovoltaic power generation power, judging whether the charge state of the energy storage system is larger than the maximum charge state, namely judging whether the energy storage residual capacity exists.

Considering the influence of the charge and discharge times on the service life of the energy storage battery, the energy storage system is not discharged any more in the period of night electricity consumption valley. If the state of charge of the energy storage battery does not reach the maximum value, the electric automobile load, other electricity loads and energy storage charging are simultaneously provided by the power grid. Note that the electricity price valley period listed here is 00 a.m.: 00 to 8 in the morning: 00 is merely illustrative, and may be specifically set according to practical circumstances, which is not limited in this embodiment.
