Energy data management
With Energy Data Management ( EDM ) is defined as the management and calculation of energy data in the electricity and gas market. Since the industry-internal billing in the electricity market takes place every quarter of an hour, in the gas market it takes place every hour, it is necessary to keep track of the quantities delivered by suppliers to their customers with extensive time series data in order to be able to check whether they have also fed corresponding quantities into the networks at the same time.
The consumption of larger customers with an annual electricity consumption of more than 100,000 kWh is recorded in a quarter-hour grid or with an annual gas consumption of more than 1.5 GWh or an output of more than 500 kW in an hourly grid by means of registered power measurement. For customers with lower consumption, only the annual consumption is measured. This is distributed over all quarter hours or hours of the year using predefined standard load profiles , which are based on statistical average values for the corresponding customer group.
The consumption measured or calculated in this way is aggregated for every quarter of an hour or hour in so-called balancing groups in order to determine the sales of the suppliers to their customers for each period of time. The same is done for the feeds. Here, too, larger feeds are measured to the quarter of an hour or to the hour, for smaller feeds such as B. Photovoltaic systems, feed-in profiles and the annual feed-in quantity are used.
