Unit commitment using dynamic programing for planning optimization and emission reduction

This paper presents a dynamic programing method for solving unit commitment (UC) problem considering the profit maximisation and emission minimisation. The UC problem is considered as tow linked optimization sub-problem: the unit-scheduled problem that can be solved by the DP method for the minimization of the transition cost, and the economic dispatch (ED) problem that can be solved by the lambda iteration method for minimization of the production cost. The studied system consists of 10 thermal units, PV system, a wind plant in order to minimize the CO2 equivalent emissions of gas turbines.
