Decarbonization and decentralization are major trends in the transformation of conventional power systems. The increase penetration renewable electricity generation into mix contributes to reduction greenhouse gas emissions. At same time, one has ensure that reliability operational flexibility as measured by respective metrics meet specified standards. This calls for a solution set engineering, economic, institutional problems, list which depends on features specific countries regions question. is due differences requirements established technical regulations, rules governing wholesale retail capacity markets, consumption, well principles underpinning management expansion operation purpose this article provide rationale feasibility efficacy integrating hybrid community mini-grids balance terms allows them operate both grid-connected islanded modes without disrupting supply consumers. main sources distributed (DG) facilities, including those based renewables energy storage systems (ESS). Load dispatching performed an intelligent automatic control system (ACS) governed decentralized algorithms, provides coordinated emergency flow automatics. Integration can be accomplished through several transmission lines form interconnection. controlled such interconnection significant system-wide economic effects. We propose technique creating mini-grids. calculations metrics. integration makes it possible availability uninterrupted consumers, lifetime grid equipment.
