Impact of Optimised Distributed Energy Resources on Local Grid Constraints

The impact of optimised distributed energy resources investment decisions in Distributed Energy Resources Customer Adoption Model (DER-CAM) were tested on the connecting network grid constraints. The test case study was a mid-rise apartment. Electricity demand data (weekdays, peak days and weekend days) for the mid-rise apartment used in the paper can be accessed from https://building-microgrid.lbl.gov/projects/how-access-der-cam . The output from the DER-CAM model is read by a MATLAB script and send to a text file for power flow analysis in NEPLAN software, NEPLAN is a power system analysis software (http://www.neplan.ch/). The output of the power flow analysis is plotted as voltage profiles (available as: voltage_profiles.xlsx) for three day-types (week, peak, weekend) each representing the 12 months of the year (24 × 12 = 288. Data points standings is available as: data_points.xlsx). Multiplying the data points by the three day-types gives a total of 864 data points for the power-flow in NEPLAN. The energy losses are plotted for the overall microgrid and is available as: energy_losses.xlsx). The microgrid network data is available as: microgrid_network.pdf.
