Book Description
The U.S. power sector has become increasingly reliant on gas pipeline networks to deliver fuel to natural gas power plants. In addition to supplying relatively low-cost fuel, gas networks offer generators flexibility in their operations through the ability to deliver fuel when needed by using gas storage facilities or linepack if the gas network is at an operating point below its design capacity. However, disruptions or stress events on the gas network - like those occurring in the Northeast and Texas in recent years - can result in limitations on gas availability to generators at times when generation is in short supply. Here we examine a period of stress that occurred in the winter of 2022 in the Western United States. Using data on the region's natural gas pipeline network and electric generators, we build an integrated gas and electric model that closely replicates the actual dispatch of the period. We then evaluate the implications of removing flexibility employed by the gas network operator, which during that period curtailed scheduled gas deliveries to other parties to increase deliveries to natural gas power plants, which requested more gas than initially forecasted. We find that without the flexibility supplied by the gas network operator, there would have been curtailment of gas generation due to gas offtake constraints, requiring the power system operator to redispatch relying on more expensive generation or to potentially shed load. A sensitivity exploring a wind drought further exacerbates the strain, illustrating the potential challenge of managing gas and grid interactions as systems move to higher shares of variable renewable electricity. Based on this example, we discuss potential coordination strategies between the two system operators to ensure that the power system can successfully utilize and rely on the flexibility offered by natural gas networks.

Resiliency of Interdependent Gas and Electricity Systems

Languages : en
Pages : 60
Book Description
According to the Presidential Policy Directive 21, the natural gas and the power systems should be able to recover quickly following a disaster and also be able to anticipate high-impact, low-probability events, rapidly recover, and absorb lessons for adapting its operation and structure for preventing or mitigating the impact of similar events in the future. All of this brings in a growing need for resiliency as the natural gas and electricity systems need to have robust recovery strategies in the face of physical, environmental, cybernetic, security or societal threats. The importance of gas and electricity system resilience increases even further, as the interdependency of the two sectors deepens, especially here in New England, where natural gas now accounts for 50% of region's total power plant capacity. In this thesis, a mixed integer linear programming (MILP) model of integrated gas and electricity system is used to do contingency analysis and determine components of both systems that are critical to improve resilience. The model's main contribution is that it represents gas dynamics accurately. Using this model, we looked at several threats at the junction of gas and electricity systems. Based on the model results, higher line-pack, and pressures, as well as additional compressor capacity investments, were shown to improve system resiliency. The model could be used as a decision support tool for policy-makers to do contingency analysis of gas-electricity systems.
