PRIVACY-PRESERVING METERING AND LOAD CONTROL IN SMART GRID
In the last decade, electrical grids have experienced an impressive evolution towards the so called Smart Grids, inspired by the Internet model. Indeed, the main driver for this evolution is the exploitation of communication networks for enabling the integration of renewable energy sources and making the energy demand closer to the time-varying production. While witnessing to the incremental deployment of Smart Grids and novel services for Smart Grids, we note a growing awareness on the risks associated to the collection of many sensitive users data. For example, monitoring the temporal trace of the energy consumption data of a given residential customer, may reveal a lot of information on …
Flexibility of grid interactive water heaters: The situation in the US
2023
Among different solutions to increase flexibility of electricity system, grid interactive water heaters (GIWHs) can make a large contribution, against a relatively low cost. They can advantageously be used within a single building, a local energy community or within an entire distribution grid, thanks to the very fast response time, low cost, highly distributed resource and widely demonstrated technology. In the near future, the flexibility potential of GIWHs will certainly increase, thanks to the advantageous flexibility programs that have been implementing in some area of the world, with the aim of coordinating several million of GIWHs with the electricity network. In this study, we asses…
Demand Response Service Certification and Customer Baseline Evaluation Using Blockchain Technology
2020
The use of Distributed Ledger Technologies such as Blockchain for certifying Demand Response services allows for the creation of a distributed system in which customers can communicate with the system operator to provide their flexibility, in a secure, transparent and traceable way. Blockchain technology also supports incentive mechanisms for users taking part in the service through the generation of utility tokens to recognize the user's contribution. This paper presents the experimental test of a novel methodology for Demand Response programs implementation by using the Blockchain technology. The latter is employed for defining a distributed Demand Response service and a new system for it…
Pašregulējoša aizsardzība pret sistēmas pārslodzi
2018
Maģistra darba mērķis ir izveidot no sistēmas veiktspējas atkarīgu sistēmas pārslodzes vadības mehānismu, kas, darbojoties fonā, mēra kopējo sistēmas slodzi un balstoties uz iegūtajiem rezultātiem regulē sniedzamo servisu apjomu. Nepietiekamas veiktspējas gadījumā tiek veidotas gaidītāju rindas jaunajiem lietotājiem, tā ļaujot efektīvi pabeigt iesāktās darbības sistēmā esošajiem lietotājiem. Lietotāji, kas atrodas gaidītāju rindā, tiek informēti par aptuveno gaidīšanas laiku, pēc kura varēs piekļūt pieprasītajai funkcionalitātei. Darbā ir aprakstīts risinājums, kas veicina augstāku servisu saņemšanas kvalitāti, izvairoties no sistēmas pārslodzes radītām atteicēm un samazinot ar sistēmas lēn…
