Efficiency of using joint schemes in dispersed generation systems

The work on competition of a Master’s degree on a speciality 8.05070108 -«Energy managament». National technical university of Ukraine «Kiev
polytechnical institute», Kiev, 2016.
Master's thesis is devoted to the models’ development formation of joint
(bivalent) schemes to meet the needs of different types of load funds, and their
performance through using of alternative energy sources.
In the master's work produced new science-based theoretical results on the
efficient using alternative energy sources, connected to each other in the bivalent
schemes. To assess the effects of different types of schemes implementation
capabilities, connecting to various types of applications in the field of alternative
energy sources in the network, depending on the desired objectives.
Analyzed the current weather database for bivalent implementation
schemes, using renewable energy sources in terms of power consumption of
existing regimes, as well as to meet the heating needs of the facility. The analysis
world experience and trends of development of alternative energy sources, as well
as the analysis of the potential of alternative energy sources in Ukraine on the basis
of which proved the feasibility of using means of distributed generation on the
basis combination of different sources in the bivalent schems.
According to the tasks created mathematical models and methods of
determination and substantiation of technical and economic efficiency of joint
schemes in the dispersal of generation systems.
Using meteorological data, simulated electrical and thermal load,
determined the economic feasibility and the relevance of bivalent schemes
implementation for a segment of consumers.
On the basis of mathematical analysis and simulation of the models using
bivalent modes of alternative energy generation technologies to solve the electrical
and thermal load consumers.
An algorithm for determining the cost-effectiveness of the implementation
of joint schemes using alternative energy sources, taking into consideration saving
money when they are used, as well as additional funds from the sale of electricity
by green tariff, and depending on the type of technical equipment network
connection.
