Frequency regulation of wind integrated power system using dual mode fuzzy

Owing to the increase in electrical load demand the dimension of interconnected energy system is increasing day by day and getting more complex with power injection from renewable technologies such as wind energy in order to supply and meet rising energy demands as well as to limit the dependency on conventional sources of power generation. However, the rising trends towards power generation via wind power will cause the challenging task to maintain the equilibrium between the power generation and load demand and hence to keep the power system frequency to standard value. Hence, in this work a new control design based on switching logic having additional fuzzy intelligence is proposed for wind integrated energy system. In addition, it is also tried to reduce the rule base for proposed design and hence to reduce the complexity of fuzzy based design. The proposed design is tested for standard load change and the results are matched with fuzzy PI and with natural response of the system to show the power of the proposed design. Further, it is also shown that doubly fed induction generator (DFIG) wind integrated system with proposed control design have the capability to improve the standard frequency profile in case of sudden change in the power demand of the energy system and hence it helps to deliver the required power to the modern clients.
