I suggest R&D directions for wide-area angle and voltage stability controls in large power systems. Existing wide-area stability controls are mostly event-driven discontinuous actions, and are termed special protection systems or remedial action schemes. More sophisticated controls act on the measured response (swing) of electrical variables to disturbances. I describe applications of response-...

Meta-heuristics optimization methods are important techniques for optimal design of the engineering systems. Numerous methods, inspired by different nature phenomena, have been introduced in the literature. A new modified version of Teaching-Learning-Based Optimization (TLBO) Algorithm is introduced in this paper. TLBO, as a parameter free algorithm, is based on the learning procedure of studen...

Due to increased load demand, the power system developers are encouraged meet quality requirements. Using harmonic filter and capacitor bank is one of essential solutions in mitigating issues. This research aims mitigate harmonics improve voltage distribution systems by using ETAP. For this purpose, a Homs city considered, which part Syrian system. The banks designed numerical analysis Optimal ...

Reactive power plays an important role in supporting real power transmission, maintaining system voltages within proper limits and overall system reliability. In this paper, the production cost of reactive power, cost of the system transmission loss, investment cost of capacitor banks and absolute value of total voltage deviation (TVD) are included into the objective function of the power flow ...
