Energy Storage Systems and Renewable Energy in Rural Electrical Power Systems

Renewable energy storage systems to make the planet sustainable is a common thread to how electricity will be delivered in the twenty first century.

There is an increasing demand both by legislation and the public for a more secured, reliable and efficient power system using dispatchable and non-dispatchable renewable resources.  However, the existing design and operational practice of the electrical power grid does not lend itself easily to the incorporation of non-dispatchable renewable energy resources. Distributive Electrical Energy Storage (DESS) is a key to the development and future of all non-dispatchable renewable energy storage systems in the electrical power grid. This paper provides an overview, discusses the state-of-the-art status and will introduce how DESS can be used to incorporate non-dispatchable renewable resources into the power grid and also provide additional benefits to the power system.

Today renewable energy, global energy sustainability and climate change is a very common topic of discussions in the media, politics, society-at-large and academic institutions. Going Green through the use of renewable energy resources and make the planet sustainable and by so doing improve the air quality and environment is a common thread to the new paradigm shift in the thinking process, how electricity will be delivered in the twenty first century.  Even in the monthly residential bill, the utility companies are starting to identify their portfolio of power generation and offer the ability to pay for newer renewable energy resources.  To many this may seem as progress in making our power systems more efficient, flexible, secure and environmentally friendly.  To this end the United States government through legislation has required that by the year 2030 that 20% of the electrical energy generated in the U. S. will be by renewable resources.  The specifics and practicality of how to accomplish this, however, have not been determined and perhaps thought through.

There are many different types of renewable energy resources such as hydroelectric, biomass, wind, solar, tidal and geothermal.  The key to the usage of renewable resources is that they are replenished by nature.  In addition they also have the advantage of having low or no emissions of carbons which make them more environmentally friendly than their fossil fuel counter parts.
