Abstract
Voltage and reactive power become one of the most critical aspects to monitor and sustain at an appropriate level in vast alternative current networks to ensure good functionality, load satisfaction, network integrity, and service quality. The network’s spending should be obtained by calculating the load flow or applying more controllable variables to it, defined as the optimization power flow. In this vein, this paper focuses on improving the network’s voltage profile, reactive power generation, and losses. The study begins with load flow estimation in various situations using the Newton–Raphson process, followed by an optimization capacity calculation using the simplified Reduced Gradient power flow method. For each system, four cases are simulated, one with and one without the SVC (Static Var Compensator) device, which is positioned in an ideal position on the IEEE 57 bus network. The confirmation of the data is carried out using the MATLAB program. A distinction is made between the two approaches based on the SVC device’s position and its reactive power generation into the network. The simulation results indicate that the generalized Reduced Gradient optimization approach (GRG-OPF) offers reasonable efficiency, quick iteration in the simulation results, the best power budget with minimal active/reactive losses and the best voltage profile specifically in the case where SVC reactive power is taken as a variant into the GRG-OPF method.
