This paper proposes a model of the thermal dynamics and of the end-use of amics and of the end-use of domestic refrigerators (fridges) and water heaters (boilers) in the foretasted scenario of the Sardinian electric network in 2020. This model is employed to evaluate the potential variations of power demand of the aggregates of fridges and...

Assessment of dynamic stability in a modern power system (PS) is becoming a stringent requirement both in operational planning and in on-line operation, due to the increasingly complex dynamics of a PS. Further, growing uncertainties in forecast state and in the response to disturbances suggests the adoption of risk-based approaches in Dynamic...

Il potenziale contributo dei carichi termostatici alla regolazione primaria di frequenza è analizzato rispetto alla disponibilità della risorsa nel tempo e all'efficacia dell'intervento, considerando anche le condizioni alle quali questo servizio potrebbe essere applicato.

In-depth security analyses of power systems (PSs) require to consider the vulnerabilities to natural and human-related threats, which may cause multiple dependent contingencies. On the other hand, such events often lead to high impact on the system, so that decision-making aimed to enhance security may become difficult. Introducing the...

This paper proposes a control framework for allowing domestic thermostatically controlled loads, such as refrigerators and electric water heaters, to provide synthetic inertia and primary frequency regulation services. The basic idea is to modify the standard thermostat logic as a function of local measurements of the grid frequency, using a...

The aim of this paper is the technical-economic assessment of the performance of the contribution of aggregated domestic thermostatic loads, as refrigerators and water heaters, to primary frequency regulation. The impact of a flexible management of this class of loads to the frequency control activities are evaluated in a power grid on a...

This paper deals with the control of aggregated domestic thermostatic loads, as refrigerators and water heaters, in order to provide an effective support to the primary frequency regulation, without compromising the secondary frequency regulation and the customer comfort. The analyzed control strategies are those defined by ENTSO-E and three...
