Formation of power supply system with the use of energy alternative sources

The aim of the work is to determine the specific technical and economic criteria that allow carrying out hierarchical decomposition of projected energy supply system that uses alternative sources of energy. A methodological approach that consistently carries out a comparative analysis of variants of such systems is considered in the design of innovative energy supply system. The result is a methodological approach, in which the base is the following sequence of operations: determination of the baseline modeling - decomposition - inform ation support - synthesis of model - checking the adequacy - specification (identification) model. There are substantiated the expediency of: carrying out decomposition of energy supply system at the design stage; the necessity of using criteria such as "efficiency-cost". To evaluate the completeness of component elements of energy innovation system it is proposed to use the criteria for an estimation of efficiency that are thermal, resource, construction, reliable etc. Scientific novelty lies in the fact that, in accordance with the proposed methodological approach, it is encouraged to undertake the decomposition not to the level of the basic components of the energy system and functional connections between the structural elements and interconnections, but to the level occurring in most parts of the system. The practical importance is when using the principle of decomposition it is possible to obtain reliable information about the state of subsystems at each level of organization of the whole power supply system that uses alternative energy sources. The use of the obtained results will allow at the designstage to predict the effectiveness of the developed system of energy supply. This involves a consideration of the mutual influence of its subsystems. This approach allows optimizing structure of energy supply system, improving the efficiency of the structural elements of the system.
