Possibilities of algebraic modelling and solving of power system optimization problems

The main goal of this paper is to present some possibilities of algebraic modelling of optimization problems in the area of power systems and their solving using General Algebraic Modelling System (GAMS). GAMS language has wide spectrum of usage from a purely mathematical problem solving to the usage in the industry problems such as chemical, electrical industry, or economy. The way of solving and modelling of specify system certainly depends of the nature of the problem and the area which it belong to. This paper will present some of optimization problems in the field of the power system, in which test results will be given for the case of multi-periodic optimal power flow conducted on a system with 4 nodes and three generators. On this particular system is performed optimization of the generator production usage during 24 hours, in which, all restrictions of presented problem has, as well, to be fulfilled.
