Coordinated Operation of the Electricity and Natural Gas Systems with Bi-directional Energy Conversion

Research output: Contribution to journalConference article in Journal

Abstract

A coordinated operation of the natural gas and electricity network with bi-directional energy conversion is expected to accommodate high penetration levels of renewables. This work focuses on the unified optimal operation of the integrated natural gas and electricity system considering the network constraints in both systems. An iterative method is proposed to deal with the nonlinearity in the proposed model. The models of the natural gas and power system are linearized in every iterative step. Simulation results demonstrate the effectiveness of the approach. Applicability of the proposed method is tested in the sample case. Finally, the effect of Power to Gas (P2G) on the daily economic dispatch is also investigated.
