“…Different methods and models have been presented based on MILP [66][67][68][69]. For instance, a longterm and multistage model for supply and interconnection expansion planning of integrated electricity and natural gas networks was proposed in [67] to determine the optimal location of new facilities; Unsihuay et al presented another integrated planning approach for hybrid power and natural gas systems [69]; and an energy hub and coupling matrix were proposed in [70][71][72] to achieve the optimal energy conversion between gas and electricity.…”

With the intensifying energy crisis and environmental pollution, the Energy Internet and corresponding patterns of energy use have been attracting more and more attention. In this paper, the basic concept and characteristics of the Energy Internet are summarized, and its basic structural framework is analyzed in detail. On this basis, couplings between the electric power system and other systems such as the cooling and heating system, the natural gas system, and the traffic system are analyzed, and the operation and planning of integrated energy systems in both deterministic and uncertain environments are comprehensively reviewed. Finally, the research prospects and main technical challenges of the Energy Internet are discussed.

Gas and power networks are tightly coupled and interact with each other due to physically interconnected facilities. In an integrated gas and power network, a contingency observed in one system may cause iterative cascading failures, resulting in network wide disruptions. Therefore, understanding the impacts of the interactions in both systems is crucial for governments, system operators, regulators and operational planners, particularly, to ensure security of supply for the overall energy system. Although simulation has been widely used in the assessment of gas systems as well as power systems, there is a significant gap in simulation models that are able to address the coupling of both systems. In this paper, a simulation framework that models and simulates the gas and power network in an integrated manner is proposed. The framework consists of a transient model for the gas system and a steady state model for the power system based on AC-Optimal Power Flow. The gas and power system model are coupled through an interface which uses the coupling equations to establish the data exchange and coordination between the individual models. The bidirectional interlink between both systems considered in this studies are the fuel gas offtake of gas fired power plants for power generation and the power supply to liquefied natural gas (LNG) terminals and electric drivers installed in gas compressor stations and underground gas storage facilities. The simulation framework is implemented into an innovative simulation tool named SAInt (Scenario Analysis Interface for Energy Systems) and the capabilities of the tool are demonstrated by performing a contingency analysis for a real world example. Results indicate how a disruption triggered in one system propagates to the other system and affects the operation of critical facilities. In addition, the studies show the importance of using transient gas models for security of supply studies instead of successions of steady state models, where the time evolution of the line pack is not captured correctly.

“…With the surge of shale gas development, the amount and proportion of gas-fired power generation will be increased as well, while the power-to-gas technology will help with the integration of the intermittent excessive electric power [6]. These factors have strengthened the interaction of a gas transmission network, and a power grid in planning [7] and operating [8]. In addition, the thermal energy generated from distributed gas power generation and cogeneration has promoted the interconnection between heat supply networks and power distribution networks.…”

What needs to be developed from the concept of ''Smart Grid'' is that: when renewable energy sources are absolutely prevailing in power generation, distributed power generation and distributed energy storage systems are widespread across the grid, and electric vehicle charging loads are prevailing in power load demands, how can the power grid support electric power as a core secondary energy source, undertake the role of a bridge between primary energy and end-use energy, and achieve the coordination and the optimization in macro energy perspective; how to guarantee the security of both macro energy and environment as well as the reliability of electricity. If a new term is needed, it should be Comprehensive Energy Network, not Energy Internet.
