RETRACTED: Self-scheduling of a novel hybrid GTSOFC unit in day-ahead energy and spinning reserve markets within ancillary services using a novel energy storage

Abstract

Solid oxide fuel cell (SOFC) and gas turbine (GT) systems are the capability to achieve 75% efficiency of their potential, because of the high flexibility of fuel and load efficiency. So, by integrating the SOFC and GT, a novel hybrid framework with high efficiency is created for implementation in the power plant systems to minimizing operating costs in the energy market. In most of the paper, only the energy market of the day-ahead is considered and the ancillary service and participation in these markets are not seen. However, one of the biggest advantages of limited energy resources is the possibility of their presence in the ancillary services markets. In this paper, at first, a novel structure of hybrid a GTSOFC and new energy storage based on a reversible solid oxide fuel cell coupled with metal hydrides and waste steam is employed in power system for selling and buying energy from the energy market and ancillary services market then to increase the efficiency a new method based on the self-scheduling method is proposed for obtaining the best result. Finally, the proposed method is implemented in a sample unit and the results proved that the proposed method is suitable for the optimization problems.
