ALLEVIATION OF LINE OVERLOADS AND VOLTAGE VIOLATIONS BY CORRECTIVE RESCHEDULING

This paper presents simple and efficient algorithms for the alleviatio n of line overloads and voltage violations by corrective rescheduling. The proposed approach utilises the decoupling of real and reactive po wer and the decomposition between optimisation without security constr aints and optimisation to satisfy security constraints. Highlights of the proposed approach are: (i) a choice of performance index which ens ures that alleviation of some of the existing violations does not crea te any fresh violations, thus avoiding the need for cycling in optimis ation and, (ii) the use of a classical optimisation technique for fast er solutions. Results for two sample test systems have been presented to validate the proposed algorithms.
