Multistabile Energiegewinnung

Für eine sektorübergreifende Energieversorgung (Haushalt, Gewerbe, Industrie, Verkehr, Wärme-/Kältesektor) mit mehr als 80 % iger regenerativer Versorgung wären die Erzeugerleistungen mehr als zu vervierfachen (Umbach 2018).. Vor diesem Hintergrund steht das deutsche Verbundnetz auch aufgrund zunehmender Dezentralisierung der Erzeugungsanlagen

What is a multi-energy system (MES)?

In this context, in fact, significantly important and widespread cases of MES are the ones based on multi or polygeneration, which can be defined as the combined production of multiple energy vectors (e.g., electricity, heat, and cooling), from a unique source of fuel.

What is multi-energy?

Hence, for the purposes of this work the concept of “multi-energy” rather refers to considering a whole-system approach to optimization and evaluation of the specific case under study (for instance, a building or a country).

How can multi-energy systems improve performance?

MES (multi-energy systems) optimally integrate different energy sectors. This invited paper provides a comprehensive MES overview from various perspectives. MES can enhance performance relative to traditionally “separate” energy systems. Key concepts discussed include aggregation models and multiple assessment criteria.

What is energy optimization scheduling of a microgrid?

The energy optimization scheduling of a microgrid is a multiobjective optimization problem with multiple constraints. The maximal energy utilization efficiency, which is known as the exergy of the DER system, can be achieved and requires the proper scheduling of the DERs, ES, and power.

Are multi-energy systems the smart grid beyond electricity?

Multi-energy systems: the smart grid beyond electricity. Environmental energy technology division seminar Lobato E, Olmos L, Gomez T, Cossent R, Andersen M, Grohnheit E, et al. Barriers in the implementation of response options aimed at mitigating unpredictability and variability of wind energy.

What is the time resolution of a multi-energy load?

The time resolution considered in the study is normally associated to the level of detail the multi-energy load is known with and to the relevant market price resolution; this resolution can for instance be down to 5 min (as in some electricity balancing markets) or half-hourly/hourly (particularly depending on real-time electricity pricing).
