As shown in Figures 8 and 4, the energy generated by the photovoltaics can meet the needs of the load most of the time, so the battery is often charged to maintain a high SOC. The difference is that strategy 1 will only be charged when the energy generated by the photovoltaics is very rich, while strategy 2 can adjust its SOC many times.
Although many scholars have conducted in-depth research on the system composed of photovoltaic–battery energy storage and proposed many energy management strategies, their work has no practical significance because the very troublesome control strategy seems to only achieve small effect, which is very unwise.
Two strategies are used in this paper. Strategy 1 is to maximize the utilization of the energy generated by photovoltaics: while the energy generated by photovoltaics cannot meet the load demand, the battery will provide energy, and while the battery cannot meet the load demand, the grid will provide energy.
However, photovoltaics are greatly affected by time and environment, and it is usually combined with batteries to form a photovoltaic – battery energy storage system to meet the load demand.
The meaning of battery energy storage is to smoothen the energy fluctuations of photovoltaics—when the load needs power, the photovoltaic power will be used first. If the power generated by photovoltaics is not enough to meet the load demand, the battery will supply power to the load.
In the same way, if the electric energy generated by the photovoltaics can meet the load demand and there is surplus, the excess electric energy will be stored by the battery, and if the battery is fully stored, the excess electric energy will be fed back to the grid.
