In the current operation mode of the PV-BESS power plant, the whole BESS is used to optimize the PV output to reduce the deviation between the day-ahead forecasted PV power and the actual PV power. The revenue of the PV-BESS power plant between the optimal typical scenario operation modes and the current operation modes are compared.
Shared energy storage operator needs to design reasonable capacity to maximise their profits. Virtual power plant operator also divides the required capacity and charging and discharging power of each VPP, according to the rated capacity given by the SESS, and adjusts the output of the internal equipment.
Considering the multi‐agent integrated virtual power plant (VPP) taking part in the electricity market, an energy trading model based on the sharing mechanism is proposed to explore the effect of the shared energy storage on multiple virtual power plants (MVPPs).
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.
Shared energy storage system involves the optimal scheduling of multiple different stakeholders, and the disorderly competition between them will reduce the efficiency of the electricity market. Non-cooperative game and cooperative game theories are used to solve the problem of interest distribution between multiple subjects .
To analyse the relationship among MVPPs in the shared energy storage system (SESS), a game‐theoretic method is introduced to simulate the bidding behaviour of VPP. Furthermore, the benefit distribution problem of the virtual power plant oper- ator (VPPO) is formulated based on the Nash bargaining theory.
