Abstract

In this paper a unique set-up of a battery storage integrated in a wind fam is presented. The wind farm Curslack in Hamburg-Bergedorf and a battery storage with a special controller set-up represent the project “Speicherregelkraftwerk. The wind farm and the battery storage share one grid. This paper presents a simulation model to estimate the potential cost savings for wind farm operators with the optimization of self-consumption of wind turbines by using a battery storage. This is one of multiple use cases that are tested in a research project that aims to make a proof of concept to combine different potentially technical benefits of a battery in a wind park grid. The goal of combining an optimized wind farm operation combined with ancillary services can generate a secure energy system without a dependency on fossil power plants. The battery is charged with wind energy and a locking mechanism assures that no grey energy is stored. When the wind turbines’ rotors are not rotating, the power consumption of the wind turbine for internal processes is mostly covered by the lithium-ion battery. An algorithm was set up to iterate through the second-based input data from the wind farm’s grid of measurement points. The developed simulation calculated savings of energy costs up to 50 % (variable energy costs depending on energy consumption) or total costs up to 39 % (with fixed cost)in comparison to the conventional coverage of the consumption through energy purchase from the grid for the month of May 2019.
