This paper introduces the concept of prosumption control where intelligent loads and distributed generation are aggregated and controlled to improve power system security. It is expected that intelligent load and generation units can respond to control / market signals and thus present an opportunity of available resources for changing the operating point (OP) of a system to one that is more secure. A prosumption pattern is then a signal to prosumers to shift their demand in time. This makes it possible to temporarily change the distribution of the power demand. A prosumption pattern is balanced, such that frequency can be maintained by other smart grid technologies. To find a prosumption pattern which can improve security, it is necessary to determine sensitivities of stability indicators such that beneficial load permutations can be identified. After introducing prosumption control and patterns, stability indicators for aperiodic small signal angular stability (ASSA) are examined, while the concept of prosumption is described. The methodology presented is shown to be able to assess the margin to instability and to predict how this margin can be affected if a load is changed in the grid. The resulting sensitivities are described and their suitability to be used to search for a prosumption pattern is evaluated.
