Power Supply System and Smart Management of Agriculture Land Using Renewable Energy Sources

Abstract

The paper presents the realization of a power supply system based on renewable energy sources (sun and wind) which is used for irrigation of vegetable crops and for smart management of agricultural land on a plot of 10 ha at the location of the village "Belegiš". The results presented in this paper are part of the project of the Mihajlo Pupin Institute, "Smart management of agricultural land and natural resources using modern technologies". The project is supported by the United Nations Development Agency and the Ministry of Environment of Republic Serbia. The implemented technical solution was awarded as one of the 11 best innovative and climate-smart solutions within the program "Local Development Resistant to Climate Change" implemented by the United Nations Development Program (UNDP) in partnership with the Ministry of Environment, with financial support from the Global Environment Fund (GEF). Within the power supply system are realized the solar power plant with an output power of 8 kW, the wind generator system with a power of 0.5 kW and battery bank of 48 Vdc / 720Ah, as primary power sources and a diesel electric generator (DEA) with a power of 7.5 kW as an auxiliary power source. In addition to this power supply system, a system for remote management of irrigation and smart management of land and natural resources has been implemented. In addition to the mentioned systems, the project also included a system of protection against atmospheric discharges and a complete video surveillance system on a given plot.
