大规模多源联合外送协调调度中基于核仁理论的利润分配

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

研究了在大规模风、光、火电联合外送体系下的协调调度及利润分配问题。基于传统的机组组合优化模型,以利润最大化为目标构建以火电机组为辅助调峰单位,提高风电、光电外送效率及稳定度的动态协调调度模型。分析对比了各电场独立运行、两方联合运行及三方联合运行时的输电线路综合利用及收益情况。基于核仁理论提出三方联合运行时的利润分配方法,该方法根据各方在联合收益中的贡献度合理分配各方利益。文中的算例仿真及利润分配方法均由专业优化软件LINGO 15编程实现,仿真结果证明了所提调度模型与利润分配方法的优越性与可行性。

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.
