OPTIMIZATION OF EQUIPMENT COMPOSITION BASED ON RENEWABLE ENERGY SOURCES IN ELECTRIC SUPPLY SYSTEMS FOR LOW POWER AUTONOMOUS CONSUMERS

Abstract

The article deals with the methodology of complex foundation and optimal choice of composition and parameters of equipment of hybrid energy complex (EC) based on renewable energy and traditional energy sources. Optimization is made by criteria of energy and economic efficiency. The experimental studies are in numerical simulation of selection process of equipment composition. For estimate calculation with a lack of initial information, simulation is performed in Microsoft Excel. For accurate optimization calculation using detailed initial information, the simulation dynamic model is developed in the environment of MATLAB Simulink. The methodology determines the optimal composition and parameters of the EC equipment based on renewable energy for power supply valve stations in real placement of gas pipeline under construction, that allow us to replace electricity consumed with renewable energy 93,5 % for a year. The economic efficiency of the project is substantiated. The methodology and calculation models can take into account the additional conditions and restrictions, the original data and models of energy converters, which give the flexibility and versatility to the methodology and calculation models. Using the methods and guidelines in the design phase will increase the competitiveness and cost effectiveness of the EC based on renewable energy sources, and optimize the total cost of electric supply low power autonomous consumers.
