—This paper focuses on the development of a control strategy for integration of wind energy conversion systems (WECS) into the electrical distribution networks with particular attention to the combined provision of energy and ancillary services. Typically, a WECS is composed by a variable speed wind turbine coupled with a direct driven permanent magnet(More)
The aim of this paper is to describe the Smart Polygeneration Microgrid (SPM), which is being constructed at the Savona Campus of the Genoa University, also thanks to funding from the Italian Ministry of Education, University and Research (amount 2.4 Million Euros). Specifically, a detailed model of the grid is presented and an optimization problem is(More)
The combined use of multitaper estimation and wavelet thresholding has proved very attractive for achieving the true power spectrum of signals peculiar to digital wireless communication systems, and thus carrying out accurate and repeatable power measurements. Nevertheless, the computational burden induced is too heavy. The paper presents a GRID computing(More)
SUMMARY The lightning performance of an overhead Multiconductor Transmission Line (MTL) system is typically represented by means of curves reporting how many lightning faults per year the system may experience as a function of its insulation level [1]. In other words, it expresses the probability that the lines are subject to an overvoltage greater than(More)
The estimation of the lightning performance of a power distribution network is of great importance to design its protection system against lightning. An accurate evaluation of the number of lightning events that can create dangerous overvoltages requires a huge computational effort, as it implies the adoption of a Monte Carlo procedure. Such a procedure(More)
Energy management system (EMS) can be considered the brain of a smart Microgrid and its performance largely influences the optimal operation of the whole infrastructure. The benefits of integration of distributed energy resources such as PV systems, energy storages and gas microturbines is directly related to the way that these resources are managed and(More)
In the framework of the 2020 European strategy, that aims the EU to become a smart, sustainable and inclusive economy, several innovative and cost-effective research and development projects are centered on the smart microgrid and sustainable energy concepts. Moreover, the need to develop energy management systems, that permit to operate energy(More)
A bi-level approach is here proposed for the optimal control of smart grids, microgrids, virtual power plants and in general for power and energy systems that include distributed energy resources, renewables and storage devices. The upper decision level has the function of fixing the values of a certain set of parameters (reference values), to be applied at(More)
