摘　　要：分布式发电(distributed generation,DG)与可中断负荷是智能电网的2种重要资源。针对电力用户停电意愿不尽相同,将配电公司的可中断负荷类型建模为离散分布的随机变量,进而建立具有分布式发电与不完全信息可中断负荷选择的配电公司能量获取模型,综合考虑到发电公司的竞价策略行为,最后建立了完整的不完全信息博弈下的电力市场模型。针对不完全信息博弈的特征,扩展改进了协同进化算法,并用于求解市场贝叶斯纳什均衡。修正的IEEE 9节点系统验证了模型与求解方法的有效性。结果表明分布式发电与可中断负荷、发电公司策略行为及不完全信息对市场均衡有着重要的影响。Distributed generation （DG） and interruptible load are two important resources of smart grid. Because different kinds of power users have different willingness to curtail their demands, the type of the interruptible loads owned by a distribution company （DISCO） was assumed to be a stochastic variable which meets a discrete distribution. Further an energy acquisition model with the distributed generation and the interruptible load under incomplete information was formulated for the distribution company. Comprehensively taking into consideration of the strategic behavior of a generation company （GENCO）, the integrated electricity market model under incomplete information was proposed finally. The coevolutionary approach was improved and further employed to solve the Bayesian Nash equilibrium of the market model. The IEEE 9-bus system appropriately modified was used to illustrate the proposed model and approach. The simulation results show that the market equilibrium is greatly affected by the distributed generation and interruptible load, the strategic behavior of the generation company and the incomplete information.
