Tools and Algorithms

Co-optimization of energy and ancillary services that takes proper account of reliability requirements (e.g., contingencies) is at the heart of tool development. This work is based upon the idea that a proper "SuperOPF"—one that is grid-wide in scope and where all limits and "products" are properly priced—is fundamental to being able to move forward with long and short-term market design and operation.

Projects

Agent-Based System Planning and Market Assessment PI: Talukdar, Sarosh This task was focused on the development of a next generation computation/simulation tool that may be of use to the emerging industry. A joint effort between Cornell, Sandia, and Carnegie Mellon University, this project involved agent design as well as...
Attribute Preserving Optimal Network Reductions PI: Tylavsky, Dan The goal of this project is the development of a unified method for generating power system network modeling equivalents with applications to traditional system analysis as well as optimization.
Benchmarking and Integrating Chance-Constrained Stochastic Unit Commitment Solution for Optimal Management of Uncertainty PI: Anderson, Lindsay This project is exploring approximate optimization methods to improve security-constrained unit commitment (SCUC) by: (a) developing robust scenario-reduction methods with assessment of impact optimality of the SCUC solution; (b) including...
Commercialization of the SuperOPF Framework PI: Chiang, Hsiao-Dong The objective of the SuperOPF project is to develop a framework that will provide proper allocation and valuation of resources through true co-optimization across multiple scenarios. Instead of solving a sequence of simpler and approximate sub-problems...
Development and Testing of New Tools PI: Zimmerman, Ray This project is developing modeling and simulation tools that take into account uncertainty in the context of multi-period scheduling and pricing for wholesale centralized electricity markets—such as those operated by ISO/RTOs. The current focus is on...
Development of Attribute Preserving Network Equivalents PI: Overbye, Tom This project is developing algorithms to construct equivalent system models that preserve desired attributes and behaviors of an interconnected electric power grid. Special emphasis is placed on applying the algorithm to develop “backbone” equivalents...
Efficient Algorithm for Finding the Global Optimizer to AC Optimal Power Flow PI: Oh, HyungSeon This project is developing an efficient algorithm to find the global solution to the AC optimal power flow problem for large power systems.
Proxy Limits and Congestion Metrics PI: Lesieutre, Bernie The purpose of this study was to determine the best way to incorporate “proxy-limits” in a DCOPF to preserve features of the solution of a more detailed ACOPF. Specific voltage and stability limits cannot be directly represented in a DCOPF and are...
Random Topology Power Grid Modeling and Automated Simulation Platform PI: Wang, Zhifang This project is developing approaches for automatically generating hypothetical power grid models that preserve key attributes of real power grids—which can then be used to study issues that affect these grids but do not require provision of sensitive...
SuperOPF Optimization Solver Enhancement PI: Chiang, Hsiao-Dong The objective of the SuperOPF project is to develop a framework that will provide proper allocation and valuation of resources through true co-optimization across multiple scenarios. Instead of solving a sequence of simpler and approximate sub-problems...
