METHODS AND SYSTEMS FOR ENHANCING CONTROL OF POWER PLANT GENERATING UNITS
First Claim
1. A control method for optimizing a fleet of generating assets in which groupings of the generating assets comprise remotely located power blocks that operate so to collectively generate a fleet output level for a market, wherein the fleet comprises multiple possible generating configurations, the method including the steps of:
- receiving real-time and historical measured values of operating parameters related to an operation of each generating asset, the measured values of the operating parameters including process inputs and process outputs;
for each of the generating assets, deriving a relational expression between the measured values of the process inputs and the measured values of the process outputs;
defining a selected operating period, the selected operating period representing a prospective operating period for the fleet;
selecting competing operating modes for the fleet for the selected operating period, wherein each competing operating mode defines an unique one of the possible generating configurations of the fleet;
based on the relational expressions and the generating configuration for each of the competing operating modes, calculating a result set for the operation of the fleet proposed during the selected operating period;
defining a cost function; and
evaluating each of the result sets pursuant to the cost function and, based thereupon, designating at least one of the competing operating modes as an optimized operating mode;
wherein the optimized operating mode comprises a power sharing recommendation between the power blocks of the fleet for generating the fleet output level.

Abstract
A method for optimizing a fleet of generating assets in which groupings include remotely located power blocks that operate so to collectively generate a fleet output level. The method may include: receiving real-time and historical measured values of operating parameters; for each of the generating assets, deriving a relational expression between the measured values of the process inputs and the measured values of the process outputs; defining a selected operating period; selecting competing operating modes for the fleet; based on the relational expressions and a generating configuration of the competing operating modes, calculating a result set for the operation of the fleet proposed during the selected operating period; defining a cost function; and evaluating each of the result sets pursuant to the cost function and, based thereupon, designating one of the competing operating modes as an optimized operating mode. The optimized operating mode may include a power sharing recommendation between the power blocks of the fleet.
