Coordination of Interdependent Electricity Grid and Natural Gas Network—a Review

The fast growth of gas-fired generating units and the new emerging power-to-gas (PtG) technology have intensified the interdependency of the electricity grid and the natural gas network. Indeed, the security and economy of one system could directly and significantly affect that of the other. In observing these new trends and changes, a coordinated optimization between the two energy systems has attracted increasing attentions in recent years, which is believed to derive much more satisfactory solutions than optimized separately. Thus, this paper provides a comprehensive review of existing works on the coordination of interdependent electricity grid and natural gas network.
