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.
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.
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.
However, assuming a system operates in islanded mode with zero grid exchange, the self-suficiency is expected to be 100 %, since all local consumption is covered Fig. 4. Self-suficiency for varying levels of storage round-trip eficiency and locally produced energy. by local generation.
