Assessment of the carrying capacity of distributed generation in distribution network considering soft open point

Abstract

The current assessment of the distributed generation (DG) supply carrying capacity accessed in the distribution network does not involve the effect of soft open point (SOP). Given this gap, a method is proposed to calculate the carrying of distributed generation accessed in the distribution power network considering the closed-loop point mode between SOP feeders. Firstly, the closed-loop feeder point mode of SOP in the distribution power network was analyzed, after which the function mode of SOP was proposed. Secondly, the reconfiguration of switches and the power flow regulation of SOP were considered and utilized to analyze the maximum DG acceptance capacity of the distribution network under various regulation means. The results showed that the acceptance of the distribution power network to DG is improved by 35.8% after considering the optimization means.
