Optimal Power Flow Using Adaptive Fuzzy Logic Controllers

الملخص EN

This paper presents an approach for optimum reactive power dispatch through the power network with flexible AC transmission systems (FACTSs) devices, using adaptive fuzzy logic controller (AFLC) driven by adaptive fuzzy sets (AFSs).

The membership functions of AFLC are optimized based on 2nd-order fuzzy set specifications.

The operation of FACTS devices (particularly, static VAR compensator (SVC)) and the setting of their control parameters (QSVC) are optimized dynamically based on the proposed AFLC to enhance the power system stability in addition to their main function of power flow control.

The proposed AFLC is compared with a static fuzzy logic controller (SFLC), driven by a fixed fuzzy set (FFS).

Simulation studies were carried out and validated on the standard IEEE 30-bus test system.
