Adaptive robust optimal reactive power dispatch in distribution networks

It is increasing popular to integrate distributed generation (DG) into distribution systems, the traditional optimal reactive power dispatch approach is no longer able to cope with it. The robust optimization (RO) theory is introduced to deal with the uncertainty of large-scale DGs. Adaptive robust optimal reactive power dispatch (AR-OPRD) is proposed to reduce the conservation of RO. An adaptive function is constructed to derive the relationship between the optimal reactive power output and active power output of an arbitrary DG. A new cutting plane algorithm is introduced to solve AR-ORPD mathematical model efficiently. In this paper, examples have been used to demonstrate the validity and effectiveness of the method.
