Abstract Different from the traditional transmission network and distribution network,the distributed generation devices in micro-grid supply power energy for the loads through the power electronic device.This paper describes the accurate mathematics models including micro-sources,flexible AC transmission system(FACTS),feeders and different types of loads considering the influence of the rectifier/inverter device.In addition,taking variation of loads and DG output power into consideration,the homopoty perturbation subinterval theory is introduced in the analysis and solution of interval power flow in the islanded micro-grid as well as the modal interval to improve the accuracy.Results validate the correctness of models and algorithms.

Key words： Islanded micro-grid power flow computation homopoty equation perturbation subinterval theory modal interval analysis
