The electric power system is one of the most complex engineered systems. It is, thus, a challenge to design a market that is efficient, transparent, and provides the proper incentives to market participants. Existing market models employ constraint relaxations, which enable various constraints to be relaxed (violated) for a high penalty price. This paper examines the practice of allowing transmission...
Spinning reserve (SR) is one of the most important resources used by system operators to maintain system security, but excess amount of SR which goes against economy must be avoided. A new unit commitment model is proposed in the paper, which adds expected customer interruption cost (ECOST) into the objective function. Thus a pretty tradeoff between system security and economy can be achieved while...
Security constrained optimal power flow programs are important tools for ensuring correct dispatch of supply while respecting the many constraints imposed by the delivery system. In addition to getting the dispatch right, locational prices must be calculated with equal precision in order to infuse market participants with the proper incentives for operation and investment. In this paper we discuss...
