Search for feasible solutions by interior point algorithms

... Vol.9. No.3. 2016. P.191-206. DOI: 10.1134/S1995423916030022 A family of interior point algorithms for linear programming problems is considered. In these algorithms, entering the feasible solution region of the original problem is presented as an optimization process of an extended problem. This extension is performed by adding a new variable. The main objective of the paper is a theoretical justification of the procedure of entering the feasible region of the original problem under the assumption ...

Optimum load distribution between heat sources based on the Cournot model

... a heat supply system with two heat energy sources operating on integrated heat networks. The mathematical approach to the solution search is represented in the graphical form and illustrates computations based on the stepwise iteration procedure for optimization of levels of loading of heat energy sources (groping procedure by Cournot) with the correspond ing computation of the heat energy price for consumers. нет

Strategic behavior of generation companies in the generation scheduling process

... medium-term generation scheduling. Power producers project the levels of market prices and predict prosperous decisions of System Operator. Power producers prepare data taking into account possible behavior of rivals. The paper presents a two-level optimization problem for the data preparation by strategic producers. Nash equilibrium is modeled to represent the behavior of generation companies. Case study demonstrates that producers tend to distort cost functions. An increase in profit of power ...
