Development of a district energy management system to benefit from the aggregated avaiable operational flexibility of the involved blocks of energy units aiming for auto-consumption and cost minimization

Classification for comfort related flexibilities Copyright: EBC Classification for comfort related flexibilities

Eletrical flexibilities within HVAC (heating, ventilation and air conditioning units) can be exploited to provide ancillary services for the grid and balance generation and load. The flexibility potentials relate to parameters that determine the human comfort in the building like e.g. temperature, humidity or air quality (represented via CO2-concentration). Within these parameters ranges exist that can be exploited to adapt electrical consumption without jeopardizing human comfort. These potentials can be used to comply with external consumption requests or on-site objectives like cost minimization or autoconsumption.

In this thesis, the potentials within the HVAC-units E.ON ERC main building are classified and quantified. The flexibility potentials within the HVAC-unit are determined via experiments. Based upon the experiments, forecasting data and a forecasting tool, electrical requests are recalculated into set-points for the comfort parameters that are sent to the BEMS (Building Energy Management System).
