Facing the challenges posed by the penetration of a new fleet of renewable energy resources which are variable and distributed in nature, transmission organizations and grid operators around the world are in the process of enhancing their dispatch systems with broader capabilities and higher economic efficiency. Traditionally, static line rating (SLR) of a line is conservatively calculated under the...
Facing the challenges posed by the penetration of a new fleet of renewable energy resources which are variable and a lot of them are distributed in nature, transmission organizations and transmission operators around the world are in the process of enhancing their dispatch systems with a broader capability and higher economic efficiency. Traditionally, static line rating (SLR) of a line is conservatively...
Day-Ahead Unit Commitment is a typical business process of regional transmission organizations (RTO) and some vertically integrated utilities to ensure enough generation capacity is committed day-ahead to meet the load for the next day. In many cases, transmission constraints are required to be taken into consideration under the framework of security-constrained unit commitment (SCUC). Transmission...
Incorporating line switching as a part of security enhancement could more effectively alleviate overloads of branch equipment in system operations. In market operations, co-optimizing transmission topology and generation dispatch could be a viable way to improve economic efficiency. This paper discusses the integration of line switching in energy and market management systems (EMS/MMS) for control...
Transmission lines are traditionally treated as non-dispatchable assets by electric utilities and regional transmission organizations. Co-optimizing transmission topology and generation dispatch could be a viable way to improve economic efficiency of market and system operations. Optimal transmission switching (OTS) can leverage grid controllability for enhancing system performance. This paper discusses...
Transmission elements are traditionally treated as non-dispatchable asset in the network. Co-optimizing transmission topology and generation dispatch could be a viable way to further maximize the market surplus and improve economic efficiency. This paper will discuss the mathematical formulation of optimal transmission switching. The benefit gain by deploying the transmission switching model will...
