Abstract

The invention relates to an electricity-gas interconnection system unit combination linear model and system considering electricity-to-gas coupling. According to the electricity-gas interconnection system, bidirectional coupling of the electricity-to-gas conversion technology and the gas turbine is considered, the unit combination problem of the gas interconnection system is studied, the lowest comprehensive operation cost of the whole system serves as the target, multiple safety constraints of an electric power system and a natural gas system are considered, and an electricity-gas interconnection system unit combination model is established and linearized to obtain a linear model. Through simulation calculation, the existing nonlinear model and the linear model are compared, the solving efficiency of the nonlinear model and the linear model is compared, meanwhile, the system operation cost and the operation state under the scenes of considering electricity-to-gas and not considering electricity-to-gas and electricity-to-gas are analyzed, and the result shows that the linear model improves the combination solving efficiency of the electricity-gas interconnection system unit, and the application of electricity-to-gas also helps to improve the economical efficiency of the electricity-gas hybrid connection system.
