Mathematical modeling use of Solar energy for hot water and cooling milk on dairy farms
Journal Title: Аграрна економіка - Year 2014, Vol 7, Issue 1
Abstract
Aggravation of the global environmental and energy crisis stimulate the development of renewable energy use in energy production systems. One of the most perspective sources of renewable energy is solar energy because of its availability, sufficiently high flux density and relative determinism. Full or partial replacement of traditional energy with solar energy can have a positive impact on a number of indicators such as environmental safety and economical efficiency, the change nature of work, etc. The highest efficiency in power supply system can be achieved through optimization of the production of traditional and renewable energy, what we will research in this article. Currently, much attention is paid to the formation of power supply systems in industrial objects from the position of physical saving and the use of renewable energy, but issues of structure optimization of equipment in energy systems with RSE usage is not sufficiently open. The main task of this research is to create a mathematical model for optimizing the structure of the hybrid energy system, composition and sizes of power equipment using solar energy. The mathematical model of the use of solar energy in technological processes hot water supply and cooling milk on dairy farms we will solve as integer optimization task of mathematical programming in which the number of thermal solar collectors for hot water supply system and their capacity, power of compression chillers will be taken as the independent variables factors. The constraints system includes inequalities that reflect energy demand for hot water supply and cooling milk on dairy farms, financial capacity of the company to purchase technological equipment for the use of solar energy, cost of energy that is produced using various power equipment. We will solve the optimization problem by carrying out minimizing the objective function, which is the cost of energy. Optimization of composition of power equipment for solar energy using will provide decrease costs for energy supply in the new version, compared to the existing from 20123 UAH to16595 UAH , payback period of additional investment will be 2.4, taking into account economic and environmental effects.
