Approaches and Instruments for Overcoming the Challenges of the Smart Grids Control

The paper considers the challenges which the modern energy systems control faces - introduction of renewable energy sources, rapidly changing loads, and energy markets liberalization. Some possible approaches for overcoming these challenges are outlined like introduction of thousands of actuating, sensing and controlling devices, smart sensor networks development, decentralized control systems implementation, web-based SCADA organization, Internet of Things (IoT) networks building. A model of a smart metering transducer is described and an architecture of a transducer network using a PLC as a gateway is developed. The key to sustainable operation of complex systems, such as the power system, and all blocks of them from one side is the collection, processing and archiving of large amounts of data about the parameters of the system and on the other hand is the fast and accurate transmission of control information. The adoption of cloud technologies in the power grids control can contribute for a safe operation and energy efficiency increase.
