Study on transaction mechanism and settlement method for large-scale participation of virtual power plant

This paper aims to explore the mechanism and settlement method of large-scale participation of virtual power plantsin electricity market trading. As a new mode of power resource aggregation and optimal scheduling,virtual power plant can improve energy utilization efficiency and market responsiveness by integrating distributed energyresources, fully stimulate virtual power plant's multi-time scale (medium and long term,spot) power and corresponding safety regulation capacity by market means through the design of trading mechanism suitable forlarge-scale participation, and the corresponding settlement method. However,virtual power plants are also faced with market problems such as tight supply and demand and weak power grid regulationability, which require emerging market entities to stimulate value,but lack a trading mechanism and settlement method that takes into account the corresponding output and regulatorycharacteristics of virtual power plants. In view of this,this paper proposes a trading mechanism an d settlement method that ADAPTS to the large-scale participation of virtual powerplants.
