Economic Transmission Analysis

Economic Transmission Analysis 

EnCompass enables economic transmission analysis by performing a security-constrained unit commitment (SCUC) and economic dispatch (SCED) using a detailed DC powerflow, including contingency constraints. As part of a nodal simulation, EnCompass calculates the locational marginal price (LMP) for each node and hub in the network on an hourly or sub-hourly basis.

LMP reports show the statistics for average, on-peak, off-peak, minimum, and maximum LMP as well as the congestion and marginal loss components. EnCompass also identifies binding transmission constraints.

You can model transmission lines with planned outages and unplanned forced outages. You can use powerflow control devices such as phase-shifting transformers and DC ties to manage congestion.

Summary reports display the total congestion value of binding constraints to help identify transmission projects with economic value. Complete nodal datasets are available for ERCOT, WECC, and the Eastern Interconnection, including all detailed transmission elements with selected contingency constraints.

EnCompass Nodal Data Models

EnCompass nodal data models are available for each of North America’s interconnects (Eastern Interconnect, ERCOT, and WECC). Each data model may simulate the system at the nodal transmission level of detail.

EnCompass nodal data models build on Horizons Energy’s National Database, which includes all the generating resources, load forecasts, fuel forecasts, emissions assumptions, and zonal topology for North America. These data models allow you to further analyze the system by connecting the powerflow and related transmission constraints to the National Database.
