计及输电网约束的电力市场动态集团投标分析
Dynamic multi-team bidding involving transmission constraints in power grid
【摘要】 为了准确模拟电力市场参与者的投标过程,在计及输电网的网络传输约束下,考虑集团投标方式,基于供应函数的Nash均衡理论和优化计算中的非线性互补方法,提出了由差分动态系统和半光滑方程组成的动态投标模型.以三个集团的电力市场为例,数值仿真分析了集团投标在不同的市场参数下系统出现的输电网运行状态和市场的Nash均衡.进一步分析了投标模型在均衡点的局部稳定性,特别探讨了投标模型中的调整参数对市场均衡点和市场稳定性的影响.
【Abstract】 To accurately simulate the bidding of market participates,this paper considers the multi-team bidding manner involving the transmission constraints of power network.Based on the Nash equilibrium theory of power markets and the nonlinear complementary method in optimisation computation,the dynamic model is composed of a different dynamic system and semi-smooth equations.A system with three multi-teams is used as a numerical examples to test the new model.Numerical simulation analyses the transmission operation states and the Nash equilibrium with respect to different market parameters.Furthermore,the local stability of bidding model at Nash equilibrium points is investigated.The effect of the adjusting parameter in bidding model to the equilibrium points and the stability is also studied.
【Key words】 power market; transmission constraints; multi-team bidding; stability;
