Energy access constitutes one of the fundamental building blocks for economic growth as well as social equity in the modern world. Access to sustainable energy is needed to achieve sustainable development. A microgrid should not be seen as a competitor to the centralized grid but as a complement.
Through examination of several implemented cases from different parts of the world the following topics are considered:
- Analysis of the interaction between centralized grids and microgrids
- Analysis of stakeholder decision parameters for electrification
- Analysis of design differences and requirements for microgrids, depending on the intended purpose and the need of the end customers
It is determined that good planning, suitable requirements and clear regulations for microgrids (in relation to centralized grids) limits the risk of stranded assets and enables better business cases for the involved stakeholders.
The paper is based on the discussion paper The role and interaction of microgrids and centralized grids in developing modern power systems – A case review publiced by ISGAN (International Smart Grid Action Network) Annex 6: Power T&D Systems.
