The graph shows summary minute values of AnS in MW. Based on these values, preliminary evaluations of size and direction of the system deviation can be made. The direction is opposite to the activation of AnS. (Settlement of negative system deviation requires activation of positive AnS). At present, summary of activated AnS automatically includes following types of AnS: secondary control, tertiary control (positive and negative), quick start (pumps), Vltava river, cold reserve (gas turbines) and Regulation energy purchased in the Electricity Balancing Market for regulation energy.
