Comparative Analysis of FOPID and 1+PI Controllers in Two-Area Load Frequency Control Systems under Dynamic Operating Conditions

For the purpose of preserving stability and reliability in the face of fluctuations and disturbances, the electrical grid is dependent on load frequency control, often known as LFC. The percentage decision point of view (FOPID) controller and the 1+PI controller are compared in this work within the context of two linear feedback control (LFC) domains. The controllers are put through their paces in this study under a variety of conditions, with the random wind generation in area 1 and the uniform wind production in area 2 being taken into consideration. Through simulation tests, FOPID and 1+PI controllers are evaluated for their capacity to manage system frequency and maintain network stability. In this evaluation, key performance parameters such difference, tie line fluctuation, and system stability are taken into consideration.
