The new increase implies a doubling of variables that allows the relaxation of the coupling between the generator time constraints and the instant system constraints. This framework allows the possibility of compromising the units that are required for the VArs they can produce, as well as for their real power. In addition, although the algorithm is very CPU intensive, the Lagrange separation structure allows its implementation in parallel computers. His work is based on that of Batut and Renaud (1992), as well as that of Baldick (1995).
Unit commitment is a complex decision-making process because of multiple constraints that should not be breached while the optimal or near optimal commitment program is in place. The article discusses the application of genetic algorithms to determine the order of short-term commitment of the thermal units in the generation of energy. The objective of the optimal compromise is to determine the on / off states of the units in the system to meet the load demand and the spin reserve requirement in each time period, so as to minimize the total generation and Several operational restrictions are met. The article examines the feasibility of using genetic algorithms and reports preliminary results to determine an order of near optimal compromise of thermal units in a studied energy system.
