The Oracle Utilities NMS Distribution Management System uses DERMS forecast updates of various fuel source types (such as wind, solar/photovoltaic, diesel, etc.) for power flow analysis. The forecast updates are loaded into the NMS PF_DER_FORECAST, PF_DER_DEMAND_RESPONSE_FORECAST, and PF_WEATHER_ZONE_FORECAST database tables. These tables may be populated by any mechanism suitable for the project's business processes and data sources. An NMS script, nms‑DERMSAdapter, can be used to load the tables with data from a CSV file or an RDBMS table.
