A novel model of load supply capability evaluation in active distribution network

[摘要] The output of the controllable distributed generation (DG) is determined by the economic dispatch strategy of the active distribution network (ADN). When we calculate the load supply capability (LSC) of ADN, the influence of the economic dispatch results must be taken into account. This paper proposes a bi-level optimization model for maximum power supply capacity of ADN based on chance constrained programming. The upper level model is used to calculate the LSC, and the lower level considers the economic dispatch of controllable DGs. Based on the improved IEEE-33 distribution system, the results show that the model can get the maximum power supply capacity that meets the economic operation requirements of ADN.
