Abstract: A concentrated solar power (CSP) plant with energy storage systems has excellent scheduling flexibility and superiority to traditional thermal power generation systems. In this paper, the operation mechanism and operational constraints of the CSP plant are specified. Furthermore, the uncertainty of the solar energy received by the solar field is considered and a robust economic dispatch model with CSP plants and renewable energy resources is proposed, where uncertainty is adjusted by the automatic generation control (AGC) regulation in the day-ahead ancillary market, so that the system security is guaranteed under any realization of the uncertainty. Finally, the proposed robust economic dispatch has been studied on an improved IEEE 30-bus test system, and the results verify the proposed model.
