A multi-criteria optimization of ancillary services in a competitive energy market

Abstract

This paper reports on a management system, which supports the power system operator to provide ancillary services in a competitive energy market under economical as well as technical objectives. In a combined optimization the minimization of the costs for providing reserve aid for covering transmission losses are presented as well as several parameters of power system operation, which represent the reliability and quality of the system like frequency control, voltage control or transmission capacity. Since the objectives compete, a Pareto-based evolution strategy was selected, in order to solve this multi-criteria optimization problem. The mathematical models representing the competitive objectives are presented and exemplary case study results are given.
