%0Computer Program %TLeast-cost Optimal Distribution Grid Expansion (LODGE) v1 %XLODGE finds the least-cost portfolio of traditional distribution system upgrades to integrate new loads and behind-the-meter DERs in combination with advanced non-wire alternative (NWA) planning solutions, such as utility-owned storage and distributed PV. Working with a set of least-cost solutions per feeder/substation allows us to benchmark and compare techno-economic performance of different traditional and NWA planning solutions. An important aspect of the LODGE model is that it includes power flow operation constraints. This means that the least-cost planning solutions delivered by LODGE are technically feasible. Available projects in LODGE portfolio include: 1) feeder reconductoring; 2) transformers upgrades; 3) non-wire alternatives, such as strategic siting and sizing of storage and distributed PV; 4) voltage regulators. %AHeleno, Miguel %AValenzuela Meza, Alan %AMoreira da Silva, Alexandre %ARodriguez Garcia, Luis %Rhttps://doi.org/10.11578/dc.20240711.4 %Uhttps://www.osti.gov/doecode/biblio/134364 %CUnited States %D2024 %GEnglish %2USDOE %1AC02-05CH11231 2024-05-10
