Abstract

In this publication the technical benefits of a mutual battery storage compared to a solution with three individual battery storages is investigated. This has been done in the context of the EU funded project “GrowSmarter” in collaboration with Rheinenergie in the living area Stegerwaldsiedlung in Cologne. In the project area each of the three buildings has its own battery storage (size varies by building). This publication investigates the options for 3 buildings connected by a private residential grid instead of a public grid, with a central battery storage and the chance of energy self-consumption. This part consists of 3 houses with 167 apartments arranged around a common yard. The roofs are covered with photovoltaic modules with an installed power of 202,5 kWp. For this area Li-Ion batteries are installed in separate containers. They have a combined capacity of 200 kWh (130, 60 and 10 kWh) with varying maximum power (30, 20 and 5 kW). It is primarily used to optimize the use of the PV power. As a result, the grade of autarky can be improved from 41 % to 45% by use of a common battery storage.
