Frequency control services by a building cooling system aggregate
No full textThis paper proposes a control strategy for managing an aggregate of commercial buildings equipped with Space Cooling Systems (SCSs), called to provide frequency control services to the main grid. The idea is to use the thermal energy stored into buildings to contribute to frequency regulation, during both normal and emergency operating conditions, always preserving the temperature comfort of end-users. Two specific algorithms are developed for two different classes of SCSs: inverter-driven SCSs, which allow the controller to define the current power demanded from the grid, and multi-state SCSs, which allow the controller to switch on-off one of the cooling units that compose the SCSs. In these two different cases, Model Predictive Control and Mixed-Integer Predictive Control, are respectively used to design a load aggregator algorithm able to coordinate the contribution to frequency regulation of each building, depending on their different thermal conditions. A test network model with a high penetration of renewable energy generation is implemented in a dedicated real-time simulation environment, in order to test the effectiveness of the proposed control techniques

No full textOperational constrained nonlinear modeling and identification of active distribution networks
No full textThis paper proposes a methodology for the identification of equivalent models of active distribution networks. Due to the increasing installation of distributed generation plants, distribution networks are acquiring an “active” role in the management of the overall power system. In this context, equivalent modeling is becoming essential for allowing transmission system operators to expand the system observability and improve the interoperability with distribution system operators. The present paper proposes a nonlinear model and an identification procedure able to take into account the prior knowledge of a given active distribution network. The result is an equivalent model, which can be easily adapted for reproducing the dynamical behavior of the network with different configurations. The proposed approach is validated through a simulation study on a Benchmark Medium Voltage Active Network
