Development of model for optimizing thermal power plant operation regimes while taking into account the criteria of efficiency and reliability

The article emphasizes the importance of tasks involving operation regimes with single-criteria to multicriteria transitions. The most important criteria for short-term and long-term operation regime optimization were defined. Mathematical model of multicriteria optimization based on economic (marginal income) and reliability (thermal power plants operational readiness factor) criteria was developed. To solve the two-criteria optimization task the mathematical method of "successive concessions" was used. Suggested model was put to test in modelling stationary operation regimes for 100 MW power unit and yielded positive results. Using the developed model will lead to increased TPP (Thermal Power Plant) competitiveness in energy marked field by reducing the fuel usage from 0.5 to 1.5%.
