Aspects of integration into the electric network of decentralized generation based on renewable energy sources: an overview of issues and tasks for the sustainable development of the energy system.

The article is devoted to an overview of the issues associated with the integration of distributed generation based on renewable energy sources into the electric power system and their impact on the operation of the electric network. The main tasks for ensuring the sustainable functioning of the integrated electric power system are considered. The application of hybrid renewable energy systems and the concept of Smart Grid and Micro Grid technologies are considered as a tool for solving the identified problems. The structure of the hybrid renewable energy system for increasing the stability of power generation in the Micro Grid is considered. The main tasks of the energy management system for an integrated Micro Grid with various renewable energy sources are described. The structure of the information technology of integrated monitoring and energy management of the hybrid renewable energy system is proposed. Information technology is a combination of a number of complex subsystems of a single system of data storage, search, display and analysis. Creating information technology based on the principle of modularity and openness allows changing its structure. One of the results of information technology work is the construction of a load profile model in the Micro Grid, which takes into account the power consumption model (taking into account the cyclical changes caused by the influence of climatic, seasonal and social factors) and the generation model from each type of renewable energy source of the hybrid system (taking into account the influence of weather factors). Predictive models are the basis for planning electricity generation from renewable energy sources and planning the load profile in the Micro Grid to implement demand side management strategies.
