A novel mechanical hardware in the loop platform for distributed generation systems

Distributed Generation and Alternative Energy Journal, vol. 28, no. 3, pp. 7-27 // 24 September 2013 The growing number of distributed generation (DG) plants has emphasized the need to perform tests before the plants begin to operate. DG systems are complex enough that setting up of an experimental phase requires high costs and efforts. Moreover,… Continua a leggere A novel mechanical hardware in the loop platform for distributed generation systems

Dispersed generation to provide ancillary services: AlpStore project

International Conference on Clean Electrical Power (ICCEP), pp. 133-138 // 29 August 2013 In the future, electrical systems should be able to integrate all users at the same time and guarantee power quality, stability and safety over time. The integration of renewable energy sources leads to new issues involving the intermittence of this generation typology.… Continua a leggere Dispersed generation to provide ancillary services: AlpStore project

Reduction method for active distribution networks

2013 IEEE Grenoble, 2013, pp. 1-6 // 20 June 2013 On-line security assessment is traditionally performed by Transmission System Operators at the transmission level, ignoring the effective response of distributed generators and small loads. On the other hand the required computation time and amount of real time data for including Distribution Networks also would be… Continua a leggere Reduction method for active distribution networks

Gas bills are falling – thanks to who?

www.huffingtonpost.it // june 2013 “In a scenario of strong contraction of the demand for energy, the new system of balancing introduced by the authorities in December 2011 has contributed -along with other regulatory interventions and recent European rules on transport capacity allocation and congestion management- to lowering the spread in the rest of Europe”. The… Continua a leggere Gas bills are falling – thanks to who?

Parallel-connected photovoltaic inverters: Zero frequency sequence harmonic analysis and solution

International Journal of Emerging Electric Power Systems, vol. 14, no. 2, pp. 199-2016 // 30 May 2013 High-power photovoltaic (PV) plants are usually constituted of the connection of different PV subfields, each of them with its interface transformer. Different solutions have been studied to improve the efficiency of the whole generation system. In particular, transformerless… Continua a leggere Parallel-connected photovoltaic inverters: Zero frequency sequence harmonic analysis and solution

Methods to detect and mitigate catalyst support carbon corrosion in PEM fuel cells

International Workshop on characterization and quantification of MEA degradation processes, Grenoble, France // 26 – 27 September 2012 Carbon black based electrodes are generally recognized as state of art for PEM fuel cell technology due to the high performance achieved with relatively low Pt content. However, the catalyst carbon support is prone to carbon oxidation.… Continua a leggere Methods to detect and mitigate catalyst support carbon corrosion in PEM fuel cells

Intelligent control for a DC micro-grid system

Universities Power Engineering Conference (UPEC), 2012 47th International, 2012, pp. 1-5 // 7 September 2012 This paper presents the dynamic response of a DC – micro-grid (DC-MG) controlled in master-slave mode. The benefits of the micro-grids (MGs) are the low cost in terms of power electronics converters and the high reliability and quality, even in… Continua a leggere Intelligent control for a DC micro-grid system
