Welcome To SSEES Website
The power grids throughout the world are changing by moving from centralized power sources and unidirectional power flows to distributed power sources and bidirectional power flows. The new grids are the so-called “smart grids”. Several initiatives are taking place worldwide to develop a “smart(er) grid” to satisfy reliability and robust requirements of the 21st century.
Sustainable community energy systems (SSEES) are an integrated approach to reduce the environmental impacts of supplying the energy requirements of a community. Here, community is a broader term, like control is. A community could be the University of Arkansas campus, a neighborhood, and industrial park, or the city of Fayetteville. An SSEES uses distributed generation with several enabling technologies, such as renewable energy sources, combined heat and power, and energy storage.
Additionally, the presence of distributed generation and energy storage improves reliability by allowing for islanded operation in the case of grid failure using the “local energy network” (microgrid) concept. This leads to tangible benefits; for example, reducing consumption and emissions from carbon-based fuels, long-term cost savings for both utilities and customers, and improving system reliability (SAIDI in the USA is significantly below countries like Japan and others).
The SSEES group works on making the enabling technologies mentioned above a reality. Work performed includes using energy storage more efficiently to integrate renewable generation in the power grid, and developing new power electronics topologies to connect distributed generation and energy storage to the grid with improved power densities and efficiencies.
