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.
