3. Summary of third chapter

The mentioned goals are followed by Chapter 3, where Anbarasi Jebaselvi and Meenakshi present modeling, simulation and analysis of permanent magnet synchronous generator (PMSG)-based wind energy conversion systems for both open- and closed-loop control strategy [8, 9]. Since the choice of wind turbine generator and optimum power from it can be achieved by matching the load and power lines close to each other [10], maximum power from wind using PMSG has been made possible by using intelligent controllers, namely fuzzy logic controllers. As PMSG suffers from strong decay of magnetic field, which tends to reduce the generated voltage at their stator terminals drastically with load, hence not much suitable for isolated operation and thus the whole analysis has been done with grid connected network. The other major limitation includes loss of flexibility in field flux control, and thus intelligent technique like fuzzy logic mechanism has been attempted along with Space Vector Modulation (SVM) to have a smooth control of field flux and load power management in PMSG. MATLAB Simulink has been used to simulate and analyze the PMSG-based wind energy conversion systems for both open- and closed-loop control strategies [11]. It is confirmed that sufficient revenue could be generated from the proposed model by implementing the same in real-time.
