Daily and Short Term Optimal Energy Management with Uncertainty

L’articolo presenta un’architettura di controllo per la gestione energetica intra day in una microrete. L’obiettivo è soddisfare un profilo accordato di scambio energetico con la rete prevalente, minimizzando i costi operativi.

This paper presents a two-level control architecture for the intra-day energy management of a microgrid. The aim is to comply with an agreed energy exchange profile with the main grid, minimizing the operating cost. The higher level is entitled for the definition of the nominal profiles of the controllable devices, based on the forecasts of demand and production.

The task of the lower level control is to reach the target energy exchange setpoint, correcting the scheduled setpoint of the controllable devices.While the high level optimization consists in the solution of a mixed integer linear programming problem, the low level controller has been implemented as a daisy chaining control scheme with a PI controller.This control architecture potentially helps to increase the reliability of the whole grid, by means of the aggregation of unpredictable energy resources and making their overall behaviour more predictable from the DSO point of view.
