Abstract

In order to independently evaluate the supporting effect of a wind turbine on the voltage of the access point, the power component theory was used to separate the single power supply from the overall effect of all power supplies. On this basis, a comprehensive evaluation method was proposed, that is, the contribution of each power supply to the node voltage was considered separately to achieve an accurate evaluation of its supporting capacity. This method comprehensively considered three indicators of voltage-to-reactive power ratio, power factor and complex power efficiency in component form, and used the method of combining entropy weight method and analytic hierarchy process to empower the evaluation index. A relative reactive voltage comprehensive evaluation system was constructed to evaluate the ability of the power supply to support the node voltage relative to its own reactive power capacity. Taking the improved IEEE 33 node distribution network as an example, the support effect of each power supply on the same node voltage was analyzed and comprehensively evaluated. The results verify the feasibility and effectiveness of the proposed method, and explain the real contribution of new energy represented by wind turbines to the access point voltage.
