Abstract

Abstract: As a key link in the clearing of the power market, unit commitment(UC) is of great significance for preparing power generation plans and ensuring the safe and economic operation of the power systems. With the construction of a unified national power market and the increasingly complex operating environment of power grids, the requirements for optimal operation of power systems continue to increase, and the research and application of UC problems have received increasing attention and concern.In this context,the modes, mathematical models and solving methods of UC are summarized, an overview of its current applications at home and abroad is provided, the challenges faced by unit commitment nowadays are analyze, and its future developmentis anticipated.

Key words: unit commitment(UC), power market, power generation plan, optimization method, novel power system
