Robust Multi-Objective H2/H∞ Load Frequency Control of Multi-Area Interconnected Power Systems Using TS Fuzzy Modeling by Considering Delay and Uncertainty

The main objective of this paper is to design a robust multi-objective H2/H∞ delayed feedback controller for load frequency control multi-area interconnected power system by taking into account all theoretical and practical constraints. To achieve more precise modelling analysis, the limitation valve position, governor, transmission delay are considered guarantee LFC system’s stability in applications. nonlinear approximated Takagi–Sugeno fuzzy model. Then, parallel distributed compensation scheme utilized designing overall system. proposed simultaneously minimizes H2 H∞ performance indexes. Finally, simulation results verify robustness effectiveness dealing with impact disturbances, model uncertainties, time delays, nonlinearities
