How to calculate the self-consumption of energy storage containers

Does shared energy storage improve self-consumption?

As a result, shared energy storage increased self-consumption rates up to 11% within the prosumer community. The proposed method provides significant economic benefits and improved power quality. Additionally, prosumers need an ESS to improve self-consumption, especially as renewable penetration levels increase in the power grid.

Does shared energy storage improve power quality?

High penetration of renewables causes power quality degradation. Voltage fluctuations decrease with energy storage unless penetration reaches 200%. As a result, shared energy storage increased self-consumption rates up to 11% within the prosumer community. The proposed method provides significant economic benefits and improved power quality.

Does ESS improve self-consumption rates?

This study maximizes self-consumption rates for increasing penetration of solar energy and using shared energy storage. These results agree with other studies showing that ESS improves SCR and SSR, ensuring power balance and reducing capacity problems. Thus, the economic benefits of the prosumers are increased by utilizing RE using ESS.

How is the fraction of self-consumption calculated?

The fraction of self-consumption is calculated as a function of the ratio of PV energy available to the electricity demand (the ‘demand ratio’) during the time step, based on the field data (see graph below): A literature review was undertaken to look at relevant aspects of PV generation and self-consumption.
