PowerPoint Presentation RESEARCH CHALLENGES IN MICROGRID TECHNOLOGIES PostDoc - DFF Juan C. Vasquez [email protected] Professor Josep M. Guerrero [email protected] 2 Microgrid Definition and Operation Microgrid Research Programme in AAU Microgrid Research activities and laboratories International Conference on Power Electrical Systems - SSD 2014 3 What is a Microgrid? Main Utility Grid PCC Household appliances and electronics DC Coupled Subsystem International Conference on Power Electrical Systems - SSD 2014 Hybrid AC/DC Microgrids Main Utility Grid PCC Household appliances and electronics DC Coupled Subsystem 4 Modes of Operation: ISLANDED International Conference on Power Electrical Systems - SSD 2014 Main Utility Grid PCC Household appliances and electronics DC Coupled Subsystem 5 Modes of Operation: GRID CONNECTED International Conference on Power Electrical Systems - SSD 2014 6 Primary Control Tertiary Control Secondary Control Modeling + Inner loops + droop Control (P/Q Sharing). International Conference on Power Electrical Systems - SSD 2014 Power Import/export from/to the grid. f/V Restoration (Island) Synchronization (Island to grid Connected mode) 7 Problem: Harmonics in Microgrids Possible solutions: - One DG unit could give more harmonics than another. (harmonic current sharing) - Voltage Harmonic Reduction (Control strategies for HC) International Conference on Power Electrical Systems - SSD 2014 Problem: Unbalances in Microgrids Possible solutions: - By means of sec. control, PCC voltage unbalances can be compensated by control signals to the primary level. - Voltage Unbalance Compensation (Control strategies) Test and verification that the proposed solutions follow the European power quality standards IEC 61727 and IEC 61000-3-6. 8 Timbus et Al.
