Integrated Electricity–Gas Operations Planning in Long-term Hydroscheduling Based on Stochastic Models

Combined Operational Planning of Natural Gas and Electric Power Systems: State of the Art

“…Correia & Lyra (1992) present also a generalized network flow model including only hydroelectric, NG and sugar cane bagasse as energy resources. Bezerra et al (2006) present a methodology for representing the NG supply, demand and transmission network within a stochastic hydrothermal scheduling model. The NG demand at each node is given by the sum of forecasted non-for-power gas and NGFPPs consumptions.…”

Optimal Expansion Planning of Energy Hub With Multiple Energy Infrastructures

“…An optimization method is introduced in [5] for enabling a long-term planning of natural gas networks with technical and economic conditions. Further studies were focused in recent years on the impact of interdependent operations of electricity and natural gas networks on power system security in [6]- [9]. The impact of natural gas infrastructure on the short-term operations of electric power system is discussed in [6].…”

“…A steady-state natural gas network flow model is presented in [8] in order to analyze the impact of natural gas on the short-term unit commitment problem. A methodology for representing the natural gas supply, demand, and transportation network in the hydrothermal power system scheduling model is introduced in [9] to address the coordination between hydrothermal generation and natural gas.…”

Globalization of the Natural Gas Market on Natural Gas Prices in Electric Power Generation and Energy Development

“…Hydro plants are able, during most of the time, to displace thermal energy production, which are then operated in complementation mode. This is achieved through hydrothermal coordination [25].…”
