When the system is at time t, the system total power generation output can be expressed as:(1) P G (t) = {P P V (t) − P E S (t) (Energy storage charging) P P V (t) + P E S (t) (Energy storage discharge)
In order to make the operation timing of ESS accurate, there are three types of the relationship between the capacity and load of the PV energy storage system: Power of a photovoltaic system is higher than load power. But this time, the capacity of ESS is less than or equal to the total demand capacity of the load at peak time;
