The increase of small size generation systems may cause congestions, hitherto unexpected, on the distribution network. To reduce the impact of congestions, the use of storage systems is one of the main countermeasure. In the paper, a storage management strategy based on a local energy market is proposed, in order to maximize the utility of an users(More)
In this paper the authors propose a novel method for tracking the maximum power point of a PV array. This method is derived by the well known incremental conductance method and the novelty consists in varying the duty cycle of the dc-dc switching converter used as MPPT tracker using a variable step size instead of a fixed step size. A practical way to(More)
This paper presents the application of a suitable control strategy for multibus microgrid applications. The control strategy, used with each distributed generation system in the microgrid is developed so as to combine the advantages of the current control and the voltage control strategies. The performance of the proposed application in terms of power(More)
During recent years the electricity supply chain (electricity production, consumption, distribution, storage, and load management) has changed. In this context a new term appears: the prosumer, that is both a consumer and producer of energy in the same entity. In the paper, an energy management approach of several prosumers aggregated in a coalition, the(More)
This paper proposes the application of the strategy control approach used for the shunt active power filter previously proposed by the authors to the inverter interface of each single micro-sources present in a Microgrid. In particular the attention has been focused on the power quality and var supporting issues. The main advantage of the proposed strategy(More)
In the last years, distributed generation (DG) and microgrid (MG) technologies have been used to moderate the stress due to main stream utility grid electricity demand increase. The dispatch of renewable distributed energy sources at present is performed in such a way that, when implemented at very large scale, their intermittency can impact on the grids,(More)
In the future Smart City, new information and communication technologies will enable a better management of the available resources. The Smart Grid infrastructure is emerging as a complex system where fine-grained monitoring and control of energy generating and/or consuming entities within the electricity network is possible. This will result to better(More)
In the last years the photovoltaic and wind power generation has been increased significantly. This paper proposes the use of a D-Statcom as inverter interface of each single micro-sources (PV and wind) present in the supply system for a water lift station situated in Marina of Strongoli (KR- Italy) for the reactive compensation to regulate PCC voltage. The(More)
The increase of renewable non-programmable production and the necessity to locally self-consume the produced energy led to utilize ever more storage systems. To correctly utilize storage systems, an opportune management method has to be utilized. This paper implements a multi-period management method for storage devices, using different management(More)
On the basis that a processing resource optimally calculates the loads scheduling one day-ahead for those prosumers operating in a demand response program, the question is: who acts the scheduling? This paper presents an electronic device named Smartbox as a low-cost and feasible home automation solution; so, given a processing resource which optimally(More)
