Fuel scheduling and accounting

A new fuel scheduling and accounting (FSA) function that allows the Houston Lighting and Power Company to schedule dispatch accurately and efficiently and monitor fuel usage throughout the entire system is described. In addition to minimizing the total cost of generation using the classical economic dispatch approach, FSA dispatches generation taking into account various fuel delivery and operational constraints. FSA provides real-time support to the dispatcher by estimating the actual fuel usage throughout the entire system and tracks the difference between actual and scheduled fuel flows. The estimation approach uses fuel flow telemetry where available compared to calculated flows based on unit input/output characteristics.<>
