Development of an emissions constrained dynamic economic dispatch methodology for real time application in energy management system.

摘要

The environmental challenges in the area of Power System Operation and Control are due to the Clean Air Act Amendments (CAAA) 1990. Important provisions of the act will constrain the operation of the power generating units such that the system total emissions of SO;The primary objective of this research is to develop and evaluate an Emissions Constrained Dynamic Economic Dispatch methodology. As all modern power systems are controlled in real time by an Energy Management System (EMS), it is required that the methodology so developed is fast enough to be solved in real time and suitable for implementation in an Energy Management System environment.;The work deals with the development of a faster variation of the Successive Approximations based Dynamic Programming (SADP) technique, named as Successive Range Adjusting Successive Approximations Dynamic Programming (SRA-SADP). Emissions Constrained Dynamic Economic Dispatch methodology is developed using a Penalty Function based optimization principle with SRA-SADP as the optimization engine for the solution in real time.;The salient points of the CAAA 1990 as applicable to Power Systems and some SO
