Due to the present \r\ninflexibility and the lack of sufficient throttling capabilities of lignite and nuclear power plants, a surplus of \r\nelectricity generation occurs during periods of high wind and solar power generation. While the specific CO2-\r\nemission is decreasing then ‒ due to the increased share of Renewables, the grid frequency is increasing (to a certain \r\nlimit). Using the grid frequency as an indicator to switch-on and off certain loads (loads that do not require power \r\npermanently (e.g. dishwashers, washing machines, dryers, fridges and freezers, heaters) could provide a simple, \r\ninexpensive demand-side management indicator to lower specific CO2‒emssions and costs (if a dynamic \r\nconsumption tariff is available). To check the truthfulness of that hypothesis, the grid and frequency data of the \r\nGerman grid of the year 2018 have been collected and a the correlation between grid frequency, power surplus, share \r\nof renewables vs. CO2-contents and price at the European energy exchange (EEX) have been calculated. The results \r\nshow: Correlation between frequency and share of renewables is quite low (r = 0.155) due to the fact that primary \r\ngrid control quickly compensates deviations from the 50 Hz nominal frequency. There is a good anti-correlation (r = -\r\n0.687) between the EEX‒prices and the share of renewables in the grid. Over the years, correlation between \r\nelectricity trading prices (EEX) and CO2 emissions is quite good (r =0.665), within the one year (2018) that \r\ncorrelation almost doesn’t exist, possibly due to the inflexibility of the bulky lignite power plants that even operate at \r\nnegative prices. \r\n"}],"ddc":["620"],"page":"1815 - 1817","title":"Triggering Demand‒Side‒Management: Correlation of electricity prices, share of renewables, CO2‒contents, and grid‒frequency in the German electricity grid.","publication":"Proceedings of the 37th European Photovoltaic Solar Energy Conference, 07 - 11 September 2020.","quality_controlled":"1","publication_status":"published"}
