  1. GridLAB-D and OpenDSS: Better Together 5 September 2019 Thomas E. McDermott Thomas.McDermott@pnnl.gov

  2. GridLAB-D originated to handle buildings, controls, grid and markets. OpenDSS Domains Thomas.McDermott@pnnl.gov

  3. OpenDSS originated from harmonics analysis and DER siting optimization. Auto-adding DG at yellow sites to defer feeder and substation upgrades Injecting harmonic currents into a grid model Thomas.McDermott@pnnl.gov

  4. OpenDSS solves time-series power flow with two loops; power flow (fixed point) and controls (queue). Note: phases are numbered and flexibly connected Thomas.McDermott@pnnl.gov

  5. Which one is better? It depends… Thomas.McDermott@pnnl.gov

  6. Example 1: feeder model conversions between CYMDIST, OpenDSS, CIM and GridLAB-D An SCE circuit layout in OpenDSS Thomas.McDermott@pnnl.gov

  7. Example 2: automates OpenDSS via Framework for Network Cosimulation (FNCS), as with GridLAB-D Total Feeder Load with Switching and PV Add 285 kW PV Open At Noon fncs_player fncs_broker opendsscmd Thomas.McDermott@pnnl.gov

  8. Example 3: linking OpenDSS power flow to GridLAB-D houses and weather over FNCS irradiance power voltage Thomas.McDermott@pnnl.gov
