ANALYSIS OF THE WORK OF INTEGRATED ENERGY CONSUMERS BY SIMULATION
I. Antypov
In recent years, Ukraine is widely distributed construction of individual houses in suburban areas where there is no central heating and gas supply. Under these conditions, promising is the use of energy from renewable energy sources. However, given the uneven geographical distribution and stochastic nature of its revenues, had the specific concentration of energy resources and the high cost of power generating equipment of alternative energy, there is a need for multiple disparate sources and battery power as part of a system that can provide savings surplus generated by the system energy, its further use in other periods of time for which the need for it grows. However, interest is the analysis of the feasibility of introducing energy into the batteries of the system of assessment of their impact on the efficiency of energy consumers in general.
The purpose of research – evaluation of the effectiveness of the system integrated energy consumers using solar energy and battery power by various types of simulation modeling.
Materials and methods of research. Summarizing the results of a number of scientific research and practical experiments, both domestic and foreign researchers proposed system integrated energy consumers, which is based on the use of solar energy and/or electricity network with the possibility of accumulation of excess in the batteries of electric and thermal energy advanced design.
By using simulation model of the integrated energy using alternative sources of energy was conducted feasibility of introducing energy accumulators of the proposed system with the assessment of their impact on the efficiency of energy consumers in general.
Results of research show that exercise per day consumed 14170 W·h of electricity and 7000 W·h of heat. However, alternative sources of energy converters produced: photovoltaic panels – 4410 W·h; solar collector – 4650 W; accumulated a group of batteries of electricity – 15650 W·h and heat – 6250 W·h.
Thus, the results show that the share of alternative energy in energy consumption for a given model parameters is within 31 % for electricity and 66 % – for the heat accordingly. However, the effectiveness of cover load consumers through the use of electrical energy is accumulated within 95...100 %, and the heat – 84...89 %.
Conclusions
As a result of the research proved the feasibility of using batteries of electric and thermal energy as part of a comprehensive energy-saving power supply of consumers using solar energy. In particular, establishes the following:
- The fate of alternative energy in energy consumption for a given model parameters is within 31 % for electricity and 66 % – for the heat accordingly.
- Efficiency cover load consumers through the use of electrical energy is accumulated within 95...100 %, and the heat – 84...89 %.
