Renewable energy and energy storage systems in rural electrical power systems: Issues, challenges and application guidelines

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 resources 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.
