The proposed study of a hybrid system with renewable energy sources powering a livestock farm falls into three directions prioritized in contemporary political, scientific and public life, namely: the use of renewable energy sources (RES), the provision of food for the population of the Earth and the utilization of various wastes.

Meeting the nutritional needs of a growing human population requires increasing the efficiency of agriculture and animal husbandry. Livestock farms are among the largest consumers of electricity in agriculture due to the energy intensity of various processes directly related to the quantity and quality of production. In addition, these farms are a source of organic waste, which, if landfilled, emits greenhouse gases, while with proper processing, biogas can be obtained from it, from which energy can be obtained without using fossil fuels with harmful emissions.

After extensive literature research and on the basis of more than 20 years of experience of the team members, conclusions were drawn and the goal of the project was formulated. The main goal of the project is the creation of a methodology for the optimization of a hybrid system (HS) with RES (autonomous or connected to the electrical grid) with application in a livestock farm. The object of the study is CH, including photovoltaic and wind generators, biogas and storage devices (SDS) (accumulators or production, storage and use of hydrogen). It is designed for powering pig and poultry farms. The methodology will allow optimization of the power of the generators and the capacity of the ZU. It will be possible to compare the efficiency of using unconventional storage devices using biogas and hydrogen with classic batteries.

Achieving the goal will be achieved through the synergy of knowledge in four areas: technical sciences, microbiology, animal husbandry and meteorology, with the main research emphasis in the field of technical sciences and microbiology.

The synergistic result will be expressed in the creation of a methodology for research and optimization of a hybrid RES system, using innovative models of wind and photovoltaic generators, obtaining energy from biogas and taking into account the peculiarities of the consumption of livestock farms. Optimization procedures will be applied based on small-step simulations of system performance over a given period of time. This allows the optimal sizing of the elements in the system (including storage devices) and increases the efficiency and security of its operation. The methodology will allow the multiplication of the obtained results for random farms and locations. Also, the possibilities of increasing the production of biogas from animal waste and other waste products from the technological process of the livestock farm and obtaining energy from it with a predictable time distribution will be investigated. These possibilities will be realized on the basis of the study of poorly studied or unstudied mixtures of organic waste, with the energy needs of the anaerobic biodegradation system being covered by a photovoltaic system.

The realism of the methodology is guaranteed by conducting the intended experiments. The purchase of specialized equipment is planned for the creation of new or for equipping existing scientific infrastructure.

A scientific team consisting of teams from three organizations with complementary competences and experience has been formed to fulfill the tasks of the project.

A plan has been drawn up for the wide dissemination of the obtained results.
