Research on Nucleolus Theory Based Profit Distribution Method for Joint Delivery System of Large-Scale Hybrid Power Generation

WU Dongwen;YU Aiqing;College of Electrical Engineering,Shanghai University of Electric Power;  
This paper studied coordination and profit distribution of joint delivery system. Large scale plants of thermal, wind and photovoltaic powers were combined in a proposed system. Based on traditional unit commitment optimization model, a dynamic dispatch model with benefit maximization as objective was established. In this model thermal power unit played auxiliary peak regulation role to improve delivery efficiency and stability of wind and PV powers. Comprehensive utilization of transmission line and income of independent mode, two-party or three-party joint mode were analyzed respectively. Benefits of each unit of three-party joint system were reasonably allocated with nucleolus theory method based on its contribution in joint income. LINGO optimization software was applied to solve the proposed model and profit distribution method, and their superiority and feasibility was proved with simulation result.
