The new prosumer tasks in the energy management of buildings

A prosumer (energy producer-consumer) usually exchanges energy and information with a microgrid, taking into consideration at the same time also such economic aspects as buying or selling energy to the highest bidder based on current rates per kilowatt hour. The proposed study describes the implementation of a new approach that allows to manage in real time the different energy flows inside a building according to a general strategy of simultaneous optimization of electrical generation, storage and controllable loads. On a local level, management may also include more prosumer points, each connected to the microgrid. In this instance, the microgrid supervises and optimizes, at a higher hierarchical level, the various energy flows with consequent synergic, mutual advantages of the different systems, both private and public.
