Modelling Approaches for Local Energy Community
Due to the absence of well documented experiences from implementations of Local Energy Communities (LECs), it is very difficult to infer implications of increased LEC integrations for the distribution network as well as for the wider society. To conduct quantifiable assessment of different control...
A Control Strategy for Seamless Interconnection of Microgrids in a Multigrid Configuration
Reference minigrids and minigrids controllers for rural India
Interconnection Protocols for Minigrids
Grid Interconnection of largely dispersed minigrids
Improving smart grid security through 5G enabled IoT and edge computing
This article investigates and analyzes the security aspects of 5G specifications from the perspective of IoT-based smart grids. As the smart grid requires high-speed and reliable communication to enable real-time grid monitoring via Internet of Things (IoT) devices, 5G can be considered a catalyst...
Review of Grid Interconnection Requirements and Synchronization Controllers for Dispersed Minigrids
As of 2019, the world population without electricity access is estimated to 770 million with most of these communities residing in sub-Saharan Africa. Nevertheless, between 2000 and 2019 the Indian population with electricity access has grown from 43% to 99%. Minigrids have played a major role in...
Electric water heater flexibility potential and activation impact in system operator perspective – Norwegian scenario case study
Simultaneous activation of demand side flexibility on thermostatically controlled loads will cause adverse impacts later in the form of rebounds. Distribution system operators must know the characterisation of the impact, as they are responsible for voltage quality of power delivery and suffer the...
Comprehensive classifications and characterizations of power system flexibility resources
Due to the increasing integration of renewable forms of generation, ageing network infrastructure, and rapid increase in peak load demand, flexibility is becoming economically more viable and hence significant role player in the future power system. There is vast amount of literature on flexibility...
