Optimization of Power Systems Infrastructure Planning with High Renewables Penetration
by Ignacio Grossmann


We consider the long-term planning of electric power infrastructures involving coal, natural gas and nuclear power with high renewable penetration (wind, solar) . To capture the intermittency of these sources, we propose a deterministic multi-scale MILP formulation that simultaneously considers annual generation investment decisions and hourly operational decisions. To overcome the computational challenges of treating hourly operational decisions within a monolithic multi-year planning horizon, we propose a decomposition algorithm, which can be extended to the case of uncertainty in power demands. Furthermore, we also consider the explicit incorporation of reliability to account for the failure of power generators.
