Implementation of Power System Stabilizer Based on Conventional and Fuzzy Logic Controllers

Abstract

To damp the low-frequency oscillations which occurred due to the disturbances in the electrical power system, the generators are equipped with Power System Stabilizer (PSS) that provide supplementary feedback stabilizing signals. The low-frequency oscillations in power system are classified as local mode oscillations, intra-area mode oscillation, and interarea mode oscillations. A suitable PSS model was selected considering the low frequencies oscillation in the inter-area mode based on conventional PSS and Fuzzy Logic Controller. Two types of (FIS) Mamdani and suggeno were considered in this paper. The software of the methods was executed using MATLAB R2015a package.
 

Conventional and Switched Capacitor Boost Converters for Solar PV Integration: Dynamic MPPT Enhancement and Performance Evaluation

“…PSO exhibits fast convergence, quickly adapting to changes in environmental conditions, and allowing the system to operate close to MPP in a timely manner [42]. Moreover, the simplicity and ease of implementation and robustness in handling noisy or fluctuating conditions marks this approach out, and it can be combined with other optimization techniques or control strategies [43,44]. These factors contribute to the effectiveness and widespread use of PSO in optimizing power extraction from PV systems.…”
