Abstract : The power system's operating point fluctuates constantly due to its extremely nonlinear nature. As a result, both actual and reactive power are impacted by the extremely low system performance. Real power shifts mostly impact the Changes in voltage magnitude are the primary determinant of changes in reactive power and system frequency. Reactive and real capabilities can therefore be managed independently. The Automatic Voltage Regulator (AVR) regulates the voltage magnitude and, therefore, the reactive power, whereas the Load Frequency Control (LFC) controls the actual power. The regulating of generator power output is known as load frequency control, or LFC, in an interconnected system. Generally speaking, fixed gain controllers are made for nominal operating settings and don't offer the optimal control performance under a variety of operating circumstances. Therefore, it is preferable to monitor operating circumstances and compute the control using updated parameters in order to maintain system performance close to optimal. Using the "Boundary Locus Method," a novel approach to identifying stabilising PID controllers for the LFC control system loop has been put forth in this study.
