Optimization methods for planning in electric power grids

Partially Adaptive Stochastic Optimization for Electric Power Generation Expansion Planning

Electric Power Generation Expansion Planning (GEP) is the problem of determining an optimal construction and generation plan of both new and existing electric power plants to meet future electricity demand. We consider a stochastic optimization approach for this capacity expansion problem under demand and fuel price uncertainty. In a two-stage stochastic optimization model for GEP, the capacity...

Implementing Virtual Buffer for Electric Power Grids

The electric power grid is a vital network for every aspect of our life. The lack of buffer between generation and consumption makes the power grid unstable and fragile. While large scale power storage is not technically and economically feasible at present stage, we argue that a virtual buffer could be effectively implemented through a demand side management strategy built upon the concept of ...

Optimal Load Shedding in Electric Power Grids

We consider the optimal load-shedding problem in electric power systems where a number of transmission lines are to be taken out of service. The nonlinear power flow equations and the binary decision variables lead to a mixed-integer nonlinear program. We show that the load-shedding problem has separable structure that can be exploited by using the alternating direction method of multipliers. W...

Expansion Planning for Electric Power Systems

Electricity is so basic to the world economy that certain electricity indices are used to express a country's economic standing (consumption or production of electricity per capita) and the standard of living enjoyed by a people (per capita electricity consumption in the domestic sector). Moreover, electricity supply has special characteristics which make the service unique as compared to other...
