Abstract: The battery energy storage station (BESS) is the current and typical means of smoothing wind- or solar-power generation fluctuations. Such BESS-based hybrid power systems require a suitable control strategy that can effectively regulate power output levels and battery state of charge (SOC).
It is well-known for the stochastic nature of the PV power generation [ 2, 3, 4, 5 ]. Due to the fluctuations, there is a deviation between the predicted output and the actual output of PV power plant, which leads to the increase of the system rotation reserve capacity.
The object of this paper is the demonstration PV-BESS power plant built in Golmud District of Qinghai, China in 2016. In the PV-BESS power plant, the capacity of the PV generation units is 50 MW, the rated power of the energy storage system is 15 MW, and the rated capacity of the energy storage system is 18 MWh.
The battery of the second system cannot only store electricity from the PV system, but also store electricity from the grid at low valley tariffs, and the stored electricity can be supplied to the buildings or sold to the grid to realize price arbitrage.
