ISGAN Smart Grid Glossary
The ISGAN Glossary is a project of the International Smart Grid Action Network, a multilateral collaboration between governments to advance the development and deployment of smarter electric grid policies, practices and systems. The Glossary utilizes OpenEI's collaborative, wiki-based platform to collect and organize definitions of smart grid concepts from a variety of high-quality international sources, and to make them freely accessible to policymakers and the public.
