One of the ways to reduce the cost of power generation in micro networks is the use of generating capacity using renewable energy sources (wind power, micro and mini hydropower plants, solar power plant, natural gas-fired plant using biogas as fuel).

Objective studies - optimization of the distributed system using the generation of different types of sources.

Materials and methods of research. To optimize the distributed system using generation sources on different physical principles necessary control system, providing the optimal input and output generating capacity, depending on the specific conditions at each time. Operational management of the generation of electricity, depending on the load curve will significantly reduce the cost of generating a kilowatt-hour by maximizing the use of renewable energy sources and implementation of the operational management of the generation with the help of a distributed control system.

The results of research. Distributed Control System provides control of generating capacity so that at any given point in time power generation was carried out from the source, with a minimum cost of power generation.

A distinctive feature of using the method of information exchange and the use of distributed generation control system is scalable microgrids and integration in the energy system, running a single system control algorithm as a whole.

Using the information exchange on the electrical network data provides the possibility of implementing power generation system using renewable and non-renewable energy sources when working together in a single low-voltage power grid.

The method comprises environmental data analysis environment (wind direction and speed, the values of solar radiation, the water flow rate, volume and biogas line pressure), the voltage and frequency on the power input from the main power line and load power. On the basis of the received data is realized the selection algorithm of the optimal power generation to provide electricity to consumers at the lowest cost of electricity generation. When you change the state of the environment and (or) consumption of electricity changes the generation source.
