Recent Trends in the Hybrid HVDC with Wind Energy a Solution to the Future Challenges in Power Transmission

Abstract

As per the recent scenario the wind energy generation is the key source of energy to avoid the greenhouse effect, since the greenhouse effect as well the global warming is a serious threat to the environment. As the current research more predominantly address the greenhouse effect, this paper concentrates more on the Green power. Hence popular to the investors, government, and general public since the 1970s. The awakening of higher investments in wind energy was caused by growing need for energy security. There are, however, numerous problems and challenges, both short and long term, with developing wind power generation. The importance of wind speed Kinetic energy in wind can be captured by wind turbines and converted to mechanical energy. Generators produce electricity from the mechanical energy. Simply, wind turbines work like a fan operating backwards. Instead of electricity making the blades turn to blow wind from a fan, wind turns the blades in a turbine to create electricity The U.S. Department of Energy identifies several key challenges in wind power energy development: risk perception, the transmission and grid limits, the low competitiveness of wind energy, low speed wind location usage, lack of Infrastructure for transmission, regulatory policy, environmental policy, environmentalists, and general public opinion. Risk perception is a challenge since wind energy is perceived risky since it depends on the presence of wind. For example, globally agriculture too depends on whether (rain and sunny days), but for agriculture we have a long history and large data sample from which to estimate the risk.
