Availability of renewable energy resources and their best utilization has now become most preferred research area among power and energy engineers. Due to the most promising features in terms of reliability and efficiency, wind energy can be kept in best corner among all green energy resources which are now being utilized for fulfilling electrical needs. The only negative point that degrades the performance of Wind Energy Conversion System (WECS) in terms of maximum utilization of available power is high variation in wind-velocity (ranging from 3 mts to 15 mts and above). Wind energy system has been widely researched so as to extract maximum active power at all possible wind speeds with least detrimental effects on overall performance of plant/system. Here sequential review on Maximum Power Point Tracking (MPPT) techniques is presented. Direct to concept approach is used to describe each method in a way that must be very useful for the beginners in this area. Proper comparison table and charts are used to summarize the work which makes readers more connected to the content. Criteria selected here for comparing different MPPT methods are efficiency, reliability, accuracy, ease in implementation, tracking speed and cost.
