Communication-aware consensus for frequency restoration in islanded microgrids
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Conference report
Restricted access - publisher's policyMicroGrids (MGs) include spatially distributed generation (DG) systems and loads that may require operating autonomously in islanded mode. The operation of islanded MGs can benefit from consensus theory and practice, ... -
Transient analysis of PV-based industrial microgrids between grid-connected and islanded modes
(2016)
Conference report
Restricted access - publisher's policyThis paper presents a networked control scheme for a photovoltaic-based industrial microgrid to adaptably operate in both grid-connected and islanded modes, and even to transfer smoothly between these two modes. The ... -
Reactive power control for loss minimization in low-voltage distributed generation systems
(2016)
Conference report
Restricted access - publisher's policyDispersed small distributed generation (DG) systems in low-voltage (LV) grids pose diverse challenges for successful grid operation. The main one is to guarantee power quality by ensuring that voltages along all the feeders ... -
A general MILP model for the sizing of islanded/grid-connected microgrids
(2016)
Conference lecture
Restricted access - publisher's policyRecently, energy systems have experienced a change of paradigm, from a large-scale centr alized approach to the in-situ exploitation of renewabl e sources. Special atte ntion has been paid to microgrids, a particular case ... -
On the optimal reactive power control for grid-connected photovoltaic distributed generation systems
(2015)
Conference lecture
Restricted access - publisher's policyThe increasing deployment of distributed generation (DG) such as photovoltaic panels (PV) connected to low-voltage (LV) grids is becoming a common trend in urban areas. The advances of information and communication technology ... -
Performance analysis of frequency restoration for parallel voltage source inverters connected with a realistic communication channel
(2015)
Conference lecture
Restricted access - publisher's policyA topic of interest within the microgrid (MG) community is to achieve accurate sharing of active and reactive power among voltage source inverters (VSI) working in parallel while keeping the voltage frequency and amplitude ... -
Active damping based on Ackermann's formula for a three-phase voltage source inverter with LCL filter
