this paper discusses the control of flexible microgrids, consisting of a redox flow batteries (rfb) and a new power conditioning system (pcs) for the rfb. considering the importance of energy storage, this study is essential in power systems that are developed cautiously. rfb is connected to power system by a dc/dc or dc/ac converter to produce a dc voltage. it is very important that this conve...

This paper presents a microgrid planning model for determining the optimal size and the generation mix of distributed energy resources (DERs) as well as the microgrid type, i.e., AC or DC. Considering the growing ratio of DC loads and DERs, DC microgrids could be potentially more beneficial than AC microgrids by avoiding the need to synchronize generators, reducing the use of converters, facili...

Making smart grids and microgrids an overwhelming and successful reality implies the consideration of a lot of challenges coming from different domains and collaboration is a keyword to seize the high ground. SEAS Shared Intelligence (SEAS SI) is a platform for algorithms sharing and execution developed under the scope of Smart Energy Aware Systems (SEAS) project to promote the intelligent mana...

It is a great challenge for DC microgrids with stochastic renewable sources and volatility loads to achieve better operation performance. This study proposes an energy management strategy based on multiple operating states for a DC microgrid, which is comprised of a photovoltaic (PV) array, a proton exchange membrane fuel cell (PEMFC) system, and a battery bank. This proposed strategy can share...

Hybrid microgrids which consist of AC and DC subgrids interconnected by power electronic interfaces have attracted much attention in recent years. They not only can integrate the main benefits of both AC and DC configurations, but also can reduce the number of converters in connection of Distributed Generation (DG) sources, Energy Storage Systems (ESSs) and loads to AC or DC buses. In this pape...

To achieve carbon neutrality by 2050, additional measures must be taken, including the extensive incorporation of renewable energy sources (RESs) [...]

Smart microgrids offer a new challenging domain for power theories and compensation techniques, because they include a variety of intermittent power sources, which can have dynamic impact on power flow, voltage regulation, and distribution losses. When operating in the islanded mode, low-voltage smart microgrids can also exhibit considerable variation of amplitude and frequency of the voltage s...

o move microgrids from the potentially irritating “hype cycle” across the dreaded “trough of disillusionment” and up the slippery “slope of enlightenment” to reach the long-sought “plateau of productivity” might seem a daunting task, particularly given the obviously melodramatic language that often accompanies technology maturation and market acceptance. Nonetheless, the promise of microgrids f...
