摘　　要：随着电力改革不断深入,研究微电网参与下的配电市场交易机制具有重要意义。针对微电网和传统供电商市场地位的不对称性,建立了有限理性策略下双寡头古诺-伯川德模型,传统供电商为优势方,采用古诺模型以稳定市场,微电网为劣势方,采用伯川德模型增强竞争力。通过仿真算例给出了纳什均衡点和局部稳定域,分析了供电差异性对模型稳定性的影响,对比了不同双寡头模型纳什均衡点处供电量、价格关系。建立了两个微电网参与下的三寡头古诺-伯川德模型,给出了纳什均衡点和局部稳定域,分析了不同微电网间的供电量、电价关系,并对不同三寡头模型进行了对比。With the deepening reform of electric power market,it is of great significance to study the trading mechanism of electricity distribution market with microgrids.Solving the asymmetry of the market position between microgrids and traditional power suppliers as a binopoly Gournot-Bernchende model under bounded rational strategy.As dominant party,traditional power suppliers adopt the Cournot model to stabilize market,the microgrid is disadvantaged party,using Bertrand model to enhance competitiveness.Nash-Equilibrium-Points and local stability domain are given through simulation examples.Analyzing the influence of power supply difference on the stability of model and comparing power supply and price at Nash equilibrium points in different binopoly models.Establishing three oligopolies Cournot-Bernard model with two micgrids,giving Nash-Equilibrium-Points and local stability domain,analyzing the power supply and price relationship between different microgrids,and comparing the different three oligopolistic models.
