Microconverters for Distributed Energy Resources

ended

The MiDER project introduces a radical redesign of the power conversion stages of distributed energy resources (DER), to ensure their large-scale incorporation in future smart grids, in which end-users will assume a prosumer role. This will be achieved through optimal incorporation of the wide band-gap technology and disengagement from magnetic components. The two main objectives of MiDER are: i) To develop a miniaturized and efficient multilevel converter (MMC) with GaN transistors and no magnetics, for grid-connected localized DERs. The advantageous characteristics of the GaN technology offer the foundations for the first monolithically integrated MMC on a single chip. ii) To study the advantages of eliminating magnetic components and filters in terms of dynamic response and power system stability. This novel approach is expected to result in efficiency improvement, notable weight and volume reduction and enhancement of the dynamic response of future DERs, while effectively addressing the oscillatory instabilities, commonly encountered during grid disturbances. The project is fully aligned with the EU policies for efficient energy generation from renewables and reduction of greenhouse gas emissions and is anticipated to have a positive socioeconomic and environmental impact. The project lies between different scientific fields, extending from material science to power electronics and power system control, aiming to provide a collaborative solution for addressing the challenges of future converter-based networks. The Fellowship offers a unique opportunity to the Researcher to acquire new knowledge and personal development skills and bridge the gap between academia and industry, through cross-sectoral training and decentralised dissemination and communication activities across Europe. Ultimately, the Action will enhance his future career perspectives, help him reach professional maturity and complete his profile as an independent researcher and project manager.
