Local Power Systems Based on Renewable Energy Sources

Popis výsledku v původním jazyce

The paper shows the possibility of forming local electric power systems (LES) based on renewable energy sources (RES) as balancing groups in the electric power system (EPS), which can maintain their performance and provide offline power supply to consumers. The article considers the problem of balancing power and electricity in a power system in which electricity consumption and generation by renewable energy sources are proportional to each other. The principle that what is generated is consumed by its own consumers is realized in the power system. At the same time, a power plant is a part of an electric power system (EPS) with thermal and nuclear power plants and is considered a separate balancing group. Power grids are designed in such a way that they can operate autonomously in both normal and wartime conditions. The sources of electricity in the transmission system are small hydroelectric power plants (SHPPs), photovoltaic power plants (PVPPs) and wind power plants (WPPs), whose electricity generation is unstable due to dependence on natural conditions. Therefore, the structure of the RES power plant includes an energy storage system with sufficient reserves to compensate for the instability of generation and balancing. As a backup, the transmission system uses the existing maneuverable capacities, electrochemical storage, hydrogen technologies and biogas plants. The system also uses a method of coordinating the schedules of electricity generation and consumption by active consumers. The need for a phased development of the electricity storage system in the power grid is taken into account. For this purpose, the composition of methods and means of RES reservation in a power system is optimized, where the optimality criterion is the cost of the energy storage system. Since the information on the cost indicators of the storage facilities is incomplete or absent, the criterion method of similarity theory is used as an optimization method. It gives satisfactory results for pre-design analysis. It is shown that from the analysis of the proportionality and sensitivity of the relative costs of possible methods and means of RES storage, it is possible to determine the relative advantages of some compared to others. An example of a power transmission system consisting of individual microgrid is given.
