20 May, 2020 Covid-related lockdown measures have triggered an unprecedented fall in commercial and industrial power demand, only mitigated by an increase in residential consumption from households transforming their homes into… offices, schools and workshops. Given the zero-marginal cost of renewable energy sources such as solar and wind, conventional power plants have taken the brunt… Continua a leggere Covid-19, power demand and… the role of energy storage

PowerTech, 2019 IEEE Milan This paper aims to present an analysis performed on real operation data of an islanded microgrid, located in Somalia. The study is carried out from the first months of deployment, in November 2015, up to October 2018, emphasizing relevant events occurred and the effects on the overall system. The investigation focuses… Continua a leggere Analyses of electrification and battery ageing processes in a real offgrid hybrid microgrid

PowerTech, 2019 IEEE Milan Microgrids are based on the same grounding schemes generally adopted in the low voltage radial distribution grids. Unlike traditional distribution grids, in islanded microgrids the neutral grounding becomes a complex problem due to different operating configurations. All the electrical devices connected to the microgrid must be modeled to guarantee the access… Continua a leggere Ground Fault Analysis in a Microgrid Scenario

PowerTech, 2019 IEEE Milan This paper presents the Multi-Good MicroGrid (MGMG) experimental facility that has been built at the Department of Energy of Politecnico di Milano to test and develop new innovative predictive optimization Energy Management System (EMS) for MGMG operation. After an introduction on the current literature status about EMS and microgrid (MG) test… Continua a leggere Numerical and experimental testing of predictive EMS algorithms for PV-BESS residential microgrid

Renew. Energy The high uncertainty associated with renewable power production limits renewable energy penetration in off-grid systems. Advanced control strategies allow for a more effective exploitation of nondispatchable sources. This paper presents a two-layer predictive management strategy for an off-grid hybrid microgrid featuring controllable and non-controllable generation units and a storage system. The upper layer… Continua a leggere Assessing the impact of a two-layer predictive dispatch algorithm on design and operation of off-grid hybrid microgrids’
