Dynamic Game-based Maintenance Scheduling of Integrated Electric and Natural Gas Grids with a Bilevel Approach. (arXiv:1712.09443v1 [math.OC])
来源于:arXiv
This paper proposes a dynamic game-based maintenance scheduling mechanism for
the asset owners of the natural gas grid and the power grid by using a bilevel
approach. In the upper level, the asset owners of the natural gas grid and the
power grid schedule maintenance to maximize their own revenues. This level is
modeled as a dynamic game problem, which is solved by the backward induction
algorithm. In the lower level, the independent system operator (ISO) dispatches
the system to minimize the loss of power load and natural gas load in
consideration of the system operating conditions under maintenance plans from
the asset owners in the upper level. This is modeled as a mixed integer linear
programming problem. For the model of the natural gas grid, a piecewise linear
approximation associated with the big-M approach is used to transform the
original nonlinear model into the mixed integer linear model. Numerical tests
on a 6-bus system with a 4-node gas grid show the effectiveness of the 查看全文>>
