Market Flow definition

Market Flow contribution of each unit in the Market-Based Operating Entity’s area = (GLDF) (Real-Time generator output) (Participation Percent/100) GLDF is the Generator to Load Distribution Factor Real-Time generator output* is the present MW level of the generator Participation Percent is the share of the unit participating in the Market-Based Operating Entity’s market

Market Flow contribution of each unit in the Market-Based Operating Entity’s area = (GLDFAdj) (Adjusted Real-Time generator output) and, GLDFAdj is the Generator to Load Distribution Factor Where the generator shift factor (GSFAdj) uses Adjusted Real-Time generator output and the load shift factor (LSFAdj) uses Adjusted Real-Time bus loads. GLDFAdj = GSFAdj - LSFAdj The real-time and one-hour ahead projected “Market Flows” will be calculated on-line utilizing the Market-Based Operating Entity’s state estimator model and solution. This is the same solution presently used to determine real-time market prices as well as providing on-line reliability assessment and the periodicity of the Market Flow calculation will be on the same order. Inputs to the state estimator solution include the topology of the transmission system and actual analog values (e.g., line flows, transformer flows, etc…). This information is provided to the state estimator automatically via SCADA systems such as NERC’s ISN link. Using an on-line state estimator model to calculate “Market Flows” provides a more accurate assessment than using an off-line representation for a number of reasons. The calculation incorporates a significant amount of real-time data, including: • Actual real-time and projected generator output. Off-line models often assume an output level based on a nominal value (such as unit maximum capability), but there is no guarantee that the unit will be operating at that assumed level, or even on-line. Off-line models may not reflect the impact of pumped-storage units when in pumping mode; these units may be represented as a generator even when pumping. Additionally off-line models may not reflect the impact of units such as wind generators. A real-time calculation explicitly represents the actual operating modes of these units. • Actual real-time bus loads. Off-line assessments may not be able to accurately account for changes in load diversity. Off-line models are often based on seasonal winter and summer peak load base cases. While representative of these peak periods, these cases may not reflect the load diversity that exists during off-peak and shoulder hours as well as off-peak and shoulder months. A real-time calculation explicitly accounts for load diversity. Off-line assessments may also reflect load reduction programs that are only in effect during peak periods. • Actual real-time breaker status. Off-line assessments are often bus models, where individual circuit breakers are...
