Performance Analysis for Load Frequency Control of Interconnected Power Systems with Different Techniques
Abstract
In the interconnected power system, frequency is one of the most important criteria determining system stability. Since interconnected systems consist of more than one region, load frequency control (LFC) is very complicated. For this reason, load frequency control analysis has been performed for interconnected power systems consisting of two and four regions in this article. Vortex Search Algorithm (VSA), Salp Swarm Algorithm (SSA) and Sine Cosine Algorithm (SCA) are used to determine the filter coefficient proportional-integral-derivative controller (PID-N) parameters of these interconnected systems. The results obtained are analyzed for % overshoot (%OS), % undershoot (%US) and settling time (ST) values for each region. It is observed that different system performances are obtained using by these methods. In addition, all system performances are significantly improved with the selected methods.
