Designing a Sustainable Future with Offshore Wind Energy

If we wish to preserve ourselves along with our planet for a sustainable future, we will need innovative and renewable approaches in order to satisfy the world's expanding energy appetite. You would be hard-pressed to find anyone more adamant on this subject than North Dakota State University's (NDSU) assistant professor of electrical and computer engineering, Nilanjan Ray Chaudhuri. He and his colleagues have compiled a book examining techniques to power homes, businesses and industry, all with the use of offshore wind energy.

Multi-terminal Direct Current Grids: Modeling, Analysis, and Control is an informative and comprehensive insight to the achievable benefits of a new type of power grid technology. It is published by the Wiley-IEEE Press and explores the mystery behind alternate current and direct current interaction.

But what makes these methods so promising? It is, after all, just wind energy.

This is true, and you could easily be forgiven for reserving a degree of suspicion. But the fact is that providing huge amounts of energy from offshore winds to onshore locations would be ineffective at best. When considering the implementation, maintenance and costs, a venture of this nature would simply be too difficult and unprofitable with conventional methods. However, by rethinking the way the energy is transferred and stored, we open up many avenues for efficient and effective offshore to onshore wind energy use.

By publishing their research, Chaudhuri and his co-authors have basically released a manual guide that promotes techniques which enable the sustainable transmission of offshore wind energy to onshore power grids. Currently, no operational practices make use of these multi-terminal direct current (MTDC) grids, but a number of conventions and seminars proposing their use have received great responses, particularly in Europe.

A resistance to change has built the hardships that currently face the implementation of MTDC grids more so than anything else. A thorough comprehension of the interaction between the grids and that of their surrounding AC systems is yet to be established. Another factor would be the commercial availability of DC side fault interruption technology for voltage sourced converter systems. Removing these barriers would enable the mass provision of a cost-effective and secure electricity supply.

The research conducted by Chaudhuri and his colleagues does indeed, as their compilation title suggests, give an understandable modeling, analysis and control structure. Readers such as myself have been compelled by the compilation. An increase in support for a system such as this would result in greater overall energy stability .
