Muravyov I.K., Golubev A.V., Korovkin A.V., Shitov R.A.  Simulation-based investigation of environmental indicators of GTE-110 gas turbine under operation and environmental changes

The paper presents the investigation results that enable assessing the influence of operation and environmental parameters on combustion process stability in the combustion chamber of GTE-110 turbine and establishing the compliance of environmental indices with guidelines in a wide range of turbine operation modes under existing process and design constraints of heat-mechanic equipment. The implementation of a simulation model of a gas-turbine unit in SimInTech simulation environment is discussed.

Keywords: gas-turbine unit, combustion chamber, NOx emissions, simulation model of a steam-gas power unit.

Shikhin V.A., Abd Elraheem A.K., Pavlyuk G.P.  Fuzzy model-based approach to integrated assessment of microgrid operating effectiveness

An approach to the estimation of microgrid operating effectiveness indicators is offered where a microgrid is represented as a multiagent system. Unified representation of agents is introduced, which is applicable to a dynamic systems class formalized as continuous, discrete, and discrete event models. The developed scheme for microgrid operating effectiveness assessment underlies the real-time optimization of microgrid performance. Standard engineering, economic, and environmental objective functions are considered as effectiveness criteria. A fuzzy model can be used as a criteria convolution tool. The algorithm proposed was tested in the design of an environmentally safe hybrid generation system for arctic application.

Keywords: multiagent system, microgrid, arctic enclave, microgrid effectiveness, fuzzy sets, multi-objective optimization, environmentally friendly technology.

Ustyugov N.V., Protalinsky O.M.  Controlling equipment power consumption profiles based on maximum power consumption forecast in a region

The paper offers an algorithm for predicting user’s power consumption allowing for the sampling time of maximum power consumption in the region. The forecast allows the end user to decrease power purchase for three planned hours on workdays that results in power cost savings without total consumption decrease. The forecast is based on the approximation techniques which enables the reduction in data processing and the decision-making based on key information. Testing results of algorithm testing on a real-life plant data are included. The algorithm offers end users the tool for effective self-dependent control of power consumption profiles for their equipment.

Keywords: control, forecast, peak hours, electric energy, power consumption profile.
