Linear generators used as direct-drive solution in wave energy conversion have the main advantage of higher efficiency and more simple and robust system. However there are some important drawbacks that should be solved to increase the reliability and feasibility. This paper will study in detail the problem of the power oscillation introduced intro the electric grid due to the zero speed point at the...
The wind energy generation, utilization and its grid penetration in electrical grid is increasing world wide. The wind generated power is always fluctuating due to its time varying nature and causing stability problem. This weak interconnection of wind generating source in the electrical network affect the power quality and reliability. The localized energy storages shall compensate the fluctuating...
Due to the recent expansion of renewable energy applications, wind energy conversion is receiving much interest all over the world. However, output fluctuations of wind generators cause network frequency variations in power systems. This can decrease the power quality and then cause a restriction of wind farm installation, especially in an isolated power system, for example, power system in a small...
