Building Systems for Automatic Control of Distributed Energy Resources on the Basis of Digital Platform

The large-scale development of distributed energy resources (DER), integrated in the medium- and low-voltage distribution networks of energy systems requires the building of the mode automatic control systems (ACS). This is due to the variety of possible circuit-mode situations that arise depending on the generation and consumption modes at a certain moment in time. These conditions make impossible the manual control of the modes of the DER distributed networks based on the visual recognition. Developing the individual DER ACS requires the correct integration and interaction with related ACSs and distribution management systems (DMS), which, according to the existing practice, seems to be quite complicated. Using the platform approach to DER control allows obtaining the optimal technical and economic control solution, including by means of the optimization algorithm application. The article describes the functional, information, software and technical architecture of the digital platform, their purpose and main functions. It reviews the features and advantages of the digital platform use for building DER ACS, describes seven main subsystems, their purpose, as well as the composition and the data flows intensity. The article also presents the objectives, components and features of the simulation modelling. Using a digital platform facilitates effective DER control, reliable functioning of the DER-based distribution networks and uninterrupted power supply to consumers.
