Abstract:The infiltration of distributed power makes the power network planning face more uncertainties.Currently，there are many research models and algorithms for power planning and power network expansion planning containing DG，but the planning results lack the systematic evaluation system.Therefore，an evaluation and analysis system based on previous studies for power network planning containing DG is proposed with certain practical merit.The evaluation system which is applied in the power network is comprehensive，objective and effective.Besides，it has relatively good academic and practical sense.
