Study on the Profit Distribution Under the Participation of Virtual Power Plants in Market Bidding

In the context of the double carbon policy, clean energy is bound to see further development, but the uncertainty of wind and photovoltaic power generation poses many problems for the operation of the grid. Virtual power plant (VPP) technology is an important solution to this problem. As China's electricity market reform continues to progress, it is important to study how virtual power plants can make more profit in the market environment and how to make a reasonable profit distribution for their survival and development. In this paper, the physical and market behaviours of various types of power generation equipment are firstly modelled. Based on this, a bidding model for VPP participation in the day-ahead market is designed with the objective of maximization the overall profit of VPP, and finally the Shapley value method is applied to allocate the profit of VPP. The results of the algorithm show that the operation mechanism of the VPP can take advantage of the different generation methods and smooth out the fluctuations in the output of wind power and PV. In addition, the profitability of each power producer has increased to a certain extent after participating in the VPP, which is conducive to attracting more power producers to participate in the VPP and further improving the profitability of the VPP.
