The electrification of heating and transportation along with the penetration of renewable energy in electricity networks has necessitated the evolution of low voltage distribution grids into smart grids. Contemporary, smart grids are realised by smart meter installations to electricity end users. In the literature, these meters aim at online metering of the grid status. Depending on this status, proactive...
Power-to-Gas is recently attracting lots of interest as a new alternative for the regulation of renewable based power system. In cases, where the re-powering of old wind turbines threatens the normal operation of the local distribution network, this becomes especially relevant. However, the design of medium-voltage distribution networks does not normally follow a common pattern, finding a singular...
High penetration of distributed energy resources (DERs) creates various protection challenges, such as protection blinding, false tripping, unsynchronized reclosing, etc. Additionally, adaptation of active network management approaches namely demand response and network reconfiguration also threats existing protection practice. In this study, a combination of a local adaptive and communication assisted...
Recent technological developments have facilitated the emergence of smart grids. In the smart grid perspective, metering and communication functionalities of the grid are greatly enhanced, thus boosting its observability and load management capabilities. This is an ideal scenario which is frequently encountered in contemporary literature. Unfortunately, in reality, operational and financial reasons...
Increased environmental awareness in the recent years has encouraged rapid growth of renewable energy sources (RESs); especially solar PV and wind. One of the effective solutions to compensate intermittencies in generation from the RESs is to enable consumer participation in demand response (DR). Being a sizable rated element, electric vehicles (EVs) can offer a great deal of demand flexibility in...
In the Smart Grid context, one of the most broadly investigated areas is the matter of flexibility. This term is still not defined in a unified way. As such, it is frequently encountered in both transmission and distribution system studies, nonetheless, with various perspectives. To some extent, the reason for this is that flexibility is a multidimensional commodity. It can be associated with a unit...
The smart grid is the digitized, modernized, updated version of archaic traditional electric grid. Advanced Metering Infrastructure (AMI) is an imperative part of the smart grid. It has replaced legacy metering, as it reports the energy consumption to the utility automatically through communication channels. AMI is also featuring to communicate control functions from utility to the smart meters. So,...
According to the new energy policy agreements, a conceptual and technological re-structuration of the Danish energy sector is expected. One of the key points for its successful implementation is the partial electrification of the heating and transportation systems. This fact, which reflects an enormous load increase, influences already the design and planning of the future power system. Great percentage...
Load forecasting is an essential part of a power system both for planning and daily operation purposes. As far as the latter is concerned, short term load forecasting has been broadly used at the transmission level. However, recent technological advancements and legislation have facilitated the installation of smart meters in many utilities. Thus, historical residential consumption data are now present...
Demand response (DR) is considered as a potentially effective tool to compensate generation intermittency imposed by renewable sources. Further, DR can instigate to offer optimum asset utilization and to avoid or delay the need for new infrastructure investment. Being a sizable load together with high thermal time constant, heat pumps (HP) can offer a great deal of flexibility in the future intelligent...
