Abstract：Low-voltage multiple-source spot network has high supplying reliability and it is beneficial to integrate DERs (Distributed energy resources). It is the developing direction of low voltage distribution system. Economic operation strategy research of low-voltage multiple-source spot network with DERs is insufficient. Based on the output power characteristic of photovoltaic, fuel cell, micro gas turbin and so on, the economic operation strategy model of low-voltage multiple-source spot network with DERs is presented. Whole cost and power balance is considered in this model. Weight coefficient is adopted to convert the multiple objective optimal problem into one objective optimal problem. The weight coefficient influence is analyzed. Case analysis result shows the optimal operation strategy presented in this article can minize the power cost.
