Abstract


The article considers the possibility of reconciliation graphics of the load and generation of renewable source of energy with the help of morphometric analysis. It is shown that inconciliation between the graphics of the load and generating of renewable sources of energy increases the irregularity of the graphics of the electrical loads.

As renewable energy sources belong to conventionally driven energy sources the reconciliation of their work with the load will be organized by the moving of the graphics of the electrical loads to a maximum daily generation of renewable energy sources particularly solar power plants. As the matter of reconciliation graphics of the electrical loads and generation of renewable sources of energy morphometric analysis has been proposed.

The main morphometric parameters of the graphics of the load and generation of renewable source of energy such as roundness, compactness, convexity and elongation have been analysed. According to the integral characteristics of these indicators we were able to prove the appropriateness of levelling of the graphic of electrical loads and reconciliation of the graphics of generating of the renewable sources of energy.

A special software package has been created for that purpose. The software provides main morphometric parameters for the graphics of the load and generation.

Keywords
