Title:

Resource Allocation for Electrical Power Networks

Abstract: 

The idea of upgrading today's electrical power grid into a Smart Grid has been seriously considered by the electric power industry, regulators, and government agencies to improve efficiency, reliability, economics, and sustainability of electricity services. Smart grid architecture should support distributed generation units, renewable energy, electric vehicles and demand-response mechanisms. In this talk, I will first outline my research projects on different aspects of the smart grid, namely control & stability of distributed generation units, renewable & storage, operation planning, and electricity market. Then, I will mainly focus on the operation planning problem.

Optimization problems for the operation planning such as resource allocation, state estimation and scheduling, are hard to solve due to the nonlinearity introduced by physical laws. I will show that there is an efficient method to tackle this nonlinearity by exploiting the physics of a power circuit. In particular, I will talk about the optimal power flow (OPF) problem, which has been studied for nearly 5 decades. Despite the fact that OPF is NP-hard in the worst case, I will prove that practical OPF problems are likely solvable in polynomial time due to the physics of a power network. I will derive various theories by studying different layers of an electrical network separately. Finally, I will talk about our recent solver for large-scale OPF problems, which is able to globally solve a 10,000-bus nonlinear (non-convex) OPF problem in a fraction of a second on a single-core machine.
