Optimized Type-2 Fuzzy Frequency Control for Multi-Area Power Systems

The objective of this study is minimizing the frequency deviation due to load variations and fluctuations renewable energy resources. In paper, a new type-2 fuzzy control (T2FLC) approach presented for (LFC) in power systems with multi-areas, demand response (DR), battery storage system (BESS), wind farms. BESS used reduce deviations caused by energy, DR utilized increase network stability fast changes. suggested T2FLC online tuned based on extended Kalman filter improve LFC accuracy coordination DR, BESS, dynamics are unknown, Jacobian extracted modeling simple multilayer perceptron neural (MLP-NN). designed evaluated through simulating 10-machine New England 39-bus test (NETS-39b) four scenarios. Simulation results verifies desired performance, indicating its superiority compared classical PI controllers, type-1 logic controllers (FLCs). mean improvement percentage about 20%.
