Sustainable microgrids: Economic, environmental and social …
Specifically, using reasonable assumptions regarding 10-MW incremental investments in a microgrid and in central-station generation with necessary transmission and distribution investments, the analysis indicates that, when considering the reliability, T&D investment deferral, local economic, environmental, and social costs and benefits of …
Economic analysis of a microgrid | IEEE Conference Publication
A microgrid is a small-scale power grid that can be operated independently or in combination with the area''s main electrical grid. Any small-scale localized station that has its own power resources, generation and loads and definable boundaries can be qualified as a microgrid. Microgrids can be intended as back-up power or to support the …
Effect of a Storage System in a Microgrid with EDR and Economic …
