Description: This Paper consists on the study of one part of wind energy system conversion, its AC side.
Renewable resources are in constant fluctuation. This situation could put in peril the energizing efficiency towards a given demand requirement.
Therefore, in order to maximize the efficiency of the renewable energy system, it is necessary to track the maximum power point of the input source, a study established under MATLAB/Simulink platform. For the wind system, the maximizing is assured while considering the optimal power curve as load characteristic, with the knowledge of the turbine characteristic Cp (λ).
Then, this work elaborates the analysis and simulation of a low speed Permanent Magnet Synchronous Generator (PMSG) driven by a vertical wind turbine through a Pulse-Width Modulation (PWM) voltage inverter, independently of the DC components of the wind system conversion, using MATLAB computer simulation. -This Paper consists on the study of one part of wind energy system conversion, its AC side.

Description: The paper presents the bacterial foraging optimization algorithm (BFOA) and particle swarm optimiza-
tion (PSO) algorithm based robust controllers for voltage deviations due to the variation of reactive power
in an isolated wind-diesel hybrid power system. The isolated wind-diesel system consists of wind energy
conversion system (WECS) utilizing a permanent magnet induction generator (PMIG). Further, a syn-
chronous generator (SG) is used with the diesel engine set for power generation. The mismatch between
generated and consumed reactive power in the system causes voltage fl uctuations, which will occur at
generator terminals. These oscillations further causes reduction in the stability and quality of the power
