An understanding of the power system losses is important not only to the power system engineer but also to the policy maker. The study focuses on improving the operating performance of electrical power system by reducing the power losses and improving the power quality. Control of the transformation ratio of power transformers and reactive power injection has been used to optimize the performance of the Jordanian electric system. The simulations have been implemented in MATLAB. Optimal transformation ratios and injected reactive power are determined for different actual operating modes (maximum, average and minimum load) for the Jordanian electric power system. Power losses versus the controlling variables are illustrated. Recommendations for optimal control variables of main substations are obtained, taking into account the limits of process control optimization. ER -
