Flexibility of electricity systems to balance generation and demand, in smart grids with high RES penetration and coordination of transmission and distribution network services
Summary:
Thesis deals with one of the newest and most important terms in the energy sector, the term flexibility and in particular the flexibility of electricity systems for the balancing and demand of electricity in smart grids, with a large penetration of Renewable Energy Sources and coordination of network services transmission and distribution of electricity.
Initially, various definitions of the term flexibility in power systems are mentioned and analyzed, and various terms of balancing and congestion management that are likely to take place in transmission and distribution systems are described. In addition, the concepts of energy managers [Transmission System Operators-(TSO), and Distribution System Operators-(DSO] are given and the importance of coordination between them for the smooth operation of the network is highlighted.
Then, both some network services and various improved functions are analyzed, combined with new digital functions able to integrate RES more easily and increase the flexibility of the existing system.
In addition, smart grid technologies such as line technology [Dynamic Line Rating – (DLR)] are described, their advantages and applications, as well as technologies and types of energy storage (batteries) for providing network services. In addition, the concepts of active consumers (prosumers or active consumers), Distributed Energy Resources (DER) and whether they can play a decisive role in the additional management of a power system are mentioned. In addition, some computing platforms and innovative technologies from the financed European programs Horizon 2020 and the active management of a power system [Active System Management – (ASM)] and how it contributes to the economic and efficient management of an electric power system.
Finally, the main pilot energy programs financed by the European Union in regions of Greece are mentioned, which aim to provide better flexibility in the power systems, and the electricity market of our country is described, as well as research projects that have been carried out or are in progress, with the participation of Independent Power Transmission Operator.
