Intelligent control systems are needed for stable and safe operation at variable wind speeds in wind energy systems that have been heavily invested in our country in recent years. The success of these control systems in wind energy systems established with large investments is tested by simulation programs. In this study, the influence of the pitch control system on the overall system stability for two different wind speeds in the 3 MVA power system created by the PSCAD simulation program is investigated.

This paper reviews different permanent magnet synchronous generator (PMSG) operated in wind energy systems and solar energy systems. A complete survey has been made towards the new contributions for harmonic compensation and new efficient topologies in the last five years to improve the efficiency, reliability and cost of the wind energy system. Different power electronic converters, which are connected between generator and the load/ grid, have been investigated on based on harmonic compensation, efficient working, and high power rating conversion. The wind generation system is still a challenge to extract smooth power from wind. To improve the power quality of the system such as islanding problem and power variation, different renewable storage systems are discussed and compared. Finally, discussion about the different controller is presented to fulfill the load or grid requirement.

Rural areas are either weakly connected to grid or have no grid access. Therefore, hybrid system is only solution for continuous undisrupted power supply. Also these rural microgrids have specific types of load. Small systems are more vulnerable to load disturbances and therefore, frequency and voltage variation have post disturbance effect on the system stability. Four different types of loads having exponential voltage and frequency characteristics are considered for the study. EPRI Load modeling has been considered based on aggregate index calculation. The system is studied for step increase/decrease in load as well as input power to the wind energy system and also the post effect of voltage & frequency change on the load with its influence on the system is considered for study purpose. The isolated microgrid proposed has wind energy system with PMSG and biogas genset (BG) with synchronous generator (SG). The system is designed in such a way that any increase/decrease in load and input power to wind is taken up by the biogas system. No additional reactive power compensator is envisaged. Accordingly, the controllers are tuned using Integral Square Error criterion for mitigate variation in load voltage & frequency.

Energy from wind is turning out to be a very promising alternative source technology in present and future power sector as it is environment-friendly and long-lasting with technological enhancements. Moreover, it occupies less space and has relative cost competitiveness. In the utility grid, the penetration of wind energy systems is expanding as the research progresses to capture greatest available wind power and operate the wind turbine (WT) with maximum possible aerodynamic efficiency. For this to accomplish a tracking controller is required to extract greatest wind power at all instants in the wide range of wind speeds. This paper presents a simple control technique for optimal power extraction from cut-in to rated wind speed range by sensing the dc-link power. It also embraces mathematical modeling of wind energy conversion system. The proposed algorithm shows excellent tracking capability under fluctuating wind conditions as revealed by power speed characteristic obtained in a wind energy system. The effectiveness of proposed strategy is verified by Matlab simulation.

This paper presents a control strategy that combines altitude and crosswind motion control for tethered wind energy systems with airborne turbines and generators. The proposed algorithm adjusts altitude and induces an appropriate level of crosswind motion to present the system with an apparent wind speed that most closely meets, but does not exceed, the rated wind speed of the on-board turbine(s), thereby tracking the turbine’s optimal power point. The adjustment of both altitude and motion control, along with the reduction in crosswind motion and altitude when the rated wind speed is exceeded, differentiates the proposed control architecture from other strategies proposed in the literature. Initial control laws and simulation results are presented for the Altaeros lighter-than-air wind energy system.

The interest towards renewable energy has been enhanced due to zero pollutant emission. Considering the present scenario, wind as a renewable source of energy is highly recommended. As it is freely available and free from pollution, wind can effectively play a role for energy generation. This can produce quality power during grid integrations as the load demands. Due to rapid variations in wind speed, wind energy systems need highly synchronized and powerful controller techniques for power regulations to overcome transients, voltage sags, and swells. A suitable and responsive controller is essential for power generation from wind energy. The controllers for wind energy system are categorized into five controller designs according to their locations to control the demand of the turbine system during grid integrations. In this chapter, various controller designs and implementations are highlighted with reference to previous works and existing studies.
