What is self-suficiency in energy systems?
The common definition of self-suficiency was originally designed for systems without storage. However, future systems will rely strongly on storage units. Storage units can introduce new levels of complexity to the calculation of self-suficiency, namely grid export of previously imported energy, differences in storage levels, and energy losses.
Is self-suficiency a metric for energy storage?
Abstract—Self-suficiency is an important metric for various energy concepts, as it reflects what share of the local consumption is covered by local generation. However, the equation commonly used in literature cannot be applied to systems with an energy storage that actively exchanges energy with the grid.
How do energy storage systems optimize energy self-sufficiency in residential buildings?
An innovative logic of the charge and discharge of the two storages as a function of energy generation and demand has been developed with the aim to optimize the energetic self-sufficiency of typical residential buildings.
What role does storage play in the calculation of self-suficiency?
Liu et al. analyse load matching in zero energy buildings, and define the self-suficiency as the ratio of directly used PV energy for the consumption of the buildings. However, it is unclear what role the storage in their investigation plays and how it is included in the calculation of self-suficiency.
Can thermal and electrical storage increase self-sufficiency of energy demand?
Currently, there is a very lack of studies that have investigated energy system configurations, which foresee the concurrent use of thermal (TES) and electrical (EES) storage having the objective to increase the self-sufficiency of energy demand for heating, cooling, and hot water production.
Can thermal storage systems increase self-consumed energy?
In order to increase self-consumed energy and minimize the energy exchange with the electricity grid, this study analyses the interaction between electrical and thermal storage systems in a building equipped with a photovoltaic plant for the on-site production of electricity and an electric heat pump used for space heating and cooling.
