Background Microgrid What is microgrid? A microgrid is a localized group of electricity sources & loads that typically operates connected to & synchronous with the traditional centralized grid but can disconnect & maintain operation autonomously as physical and/or [1] economic conditions dictate. Its characteristics: Source: Microgrid Institute • • • Greater Resilience Less Emission Limited Capacity Relatively High Cost Diverse stakeholders [1] U. S. Department of Energy. (2019). About Microgrids. Retrieved from: https: //building-microgrid. lbl. gov/about-microgrids
Background-preliminary Analysis Project goal • Establishing models to make a feasible plan of microgrid to further build a reasonable market structure for stakeholders. Related management tools & financial policies are also summarized based on the models. Important aspects • • Control all the inputs of the microgrid model – How to make reasonable assumptions? Chose components for microgrid and market Structure – How to optimize the modeling? Sensitive analysis – What are the inherent uncertainties? Stakeholder analysis – How will different stakeholders react to different choices?
