Abstract

The authors present a methodology for evaluation of optimum active power generation scheduling and alleviation of overvoltage and undervoltage conditions in a day-to-day operation of large power systems. Sequential optimization approach is adopted for active and reactive power optimization problems to take the advantage of loose coupling between the two problems. Minimization of fuel cost is considered as an objective function for active power optimization, while for reactive power optimization the objective function selected is to minimize the sum of the voltage deviations by the least square minimization technique. Voltage dependency of loads are included in the model. The method is computationally very fast and seems to be suitable to be implemented in real time dispatch centres. Results obtained for IEEE 30-bus test system are presented for illustration purposes
