This paper presents a novel hybrid method for solving the security constrained unit commitment (SCUC) problem. The proposed formulation requires much less computation time in comparison with other methods while assuring the accuracy of the results. Furthermore, the framework provided here allows including an accurate description of warmth-dependent startup costs, valve point effects, multiple f...

Environmental concerns and depletion of nonrenewable resources has made great interest towards renewable energy resources. Cleanness and high potential are factors that caused fast growth of wind energy. However, the stochastic nature of wind energy makes the presence of energy storage systems (ESS) in wind integrated power systems, inevitable. Due to capability of being used in large-scale sys...

Wind power is one of the fastest growing renewable sources of generation in the U.S. and many other countries. As wind-generated electricity continues to grow, electric utilities increasingly grapple with the challenges of connecting that power to the grid although maintaining system security. It is difficult to predict and control the output of wind generation because of wind intermittency and...

This paper summarizes the technical activities of IEEE Task Force on Solving Large Scale Optimization Problems in Electricity Market and Power System Applications. was established by Technology Innovation Subcommittee to first review state-of-the-art security-constrained unit commitment (SCUC) business model, its mathematical formulation, solution techniques solving electricity market clearing ...

As part of the day-ahead market clearing process, MISO solves one of the most challenging Security Constrained Unit Commitment (SCUC) models. With the footprint expansion and increased financial activities, the day-ahead market unit commitment may encounter performance challenges from time to time. This paper reviews MISO’s day-ahead market clearing process and identifies the factors contributi...
