When the battery is full, the excess power is directed back into the solar panels, resulting in a temporary increase in voltage. This method effectively reduces the overall efficiency of the system because the excess energy is essentially lost.
As shown in Fig. 1, the scale of energy storage battery pack from small to large is single battery (cell), battery module, battery cluster, battery system, etc., while the energy storage battery pack is composed of single batteries in series and parallel and connected to the power grid through the power conversion system.
The battery energy storage power station is composed of battery clusters, PCS, lines, bus bar, transformer, and other power equipment. When the scale is large, the simulation method can be used to evaluate. When the scale is relatively small, the enumeration method can be used for reliability evaluation.
Its reliability can be calculated by the reliability evaluation method of series–parallel structure. The evaluation index is the equivalent availability and equivalent unavailability of the battery cluster. The second layer is the reliability evaluation of battery energy storage power station.
They handle the excess energy in the following ways: This is the most direct way of dealing with the excess energy. When the battery is full, the excess power is directed back into the solar panels, resulting in a temporary increase in voltage.
