Wind energy impact in fossil fuel management: A multi-energy OPF approach

The increasing penetration of wind generation in electric power systems has made evident the necessity of a unified energy infrastructure interdependency analysis, in order to explore the optimal use of fossil fuel-based generation and the security constraints associated with different energy infrastructures. In this context, the optimal generation dispatch of online generating units is important in the daily operation planning. This paper proposes a multi-energy day-ahead optimal power flow (OPF) approach in order to assess the wind energy penetration in an electric power system and its impact on the fossil fuel-based generation management. The applicability of the proposed approach is demonstrated by integrating a 15-node natural gas network and a 4-node coal distribution system with the IEEE 118-bus power system.
