Controlling production units and consumers with an energy management system

Trendi in napovedi velike rasti rabe električne energije v svetu, vse bolj spodbujajo razvoj ne le proizvodne tehnologije, ampak tudi tehnologije za optimizacijo rabe električne energije z razvojem sistemov za upravljanje z energijo (v nadaljevanju EMS - »Energy Management Systems«). Slednji obetajo ne le optimizacijo proizvodnje in rabe električne energije in s tem prihranke, ampak tudi možnost izvajanja storitev fleksibilne proizvodnje in rabe energije tako za potrebe trga z energijo kot tudi za potrebe upravljavcev prenosnih in distribucijskih omrežij [23]. Osnova izvedbe tovrstnih sistemov je komunikacija s porabniki in proizvodnimi enotami. Ta nam preko meritev relevantnih fizikalnih veličin omogoča napovedovanje proizvodnje in porabe električne energije. Na podlagi napovedi lahko nato ročno (uporabnik sam/preprosti EMS) ali avtomatsko (pametni EMS) sprejmemo ustrezne odločitve in na koncu ponovno preko komunikacijskih povezav krmilimo proizvodne enote in porabnike. Glavni izziv pri izvedbi komunikacijske povezave z napravami predstavljajo raznolikost naprav na trgu, mnogoterost uporabljenih komunikacijskih tehnologij in protokolov ter velika možnost izbire tehnologij hranjenja in obdelave merjenih podatkov. Cilj tega projekta je bil fizično in komunikacijsko povezati porabnike in proizvodne enote znotraj eksperimentalnega sistema v Laboratoriju za energetiko FERI. S tem omogočiti meritve ključnih fizikalnih veličin in krmiljenje teh naprav za potrebe razvoja inteligentnega EMS nove generacije, hkrati pa zagotoviti stalno spremljanje (monitoring) vseh naprav v eksperimentalnem sistemu.Trends and predictions of the large increase in the use of electricity in the world are increasingly encouraging the development of not only production technology but also technologies for optimizing the use of electricity by developing energy management systems (hereinafter EMS). The latter are promising not only the optimization of the production and use of electricity, and thus the savings, but also the possibility of providing flexible production and use services for both the energy market and the needs of transmission and distribution network operators [23]. The basis for implementing such systems is communication with consumers and production units. Through measurements of relevant physical quantities, this enables us to predict the production and consumption of electricity. Based on the forecast, you can then manually (user / simple EMS) or automatic (smart EMS) to make the right decisions, and finally, through the communication links, we control the production units and consumers. The main challenge in implementing a communication link with devices is the variety of devices on the market, the variety of used communication technologies and protocols, and the great choice of technologies for storing and processing the measured data. The aim of this project was to physically and communicate the consumers and production units within the experimental system in the Faculty of Electrical Engineering and Computer science of Maribor in Laboratory for Energy. This enables the measurement of key physical quantities and control of these devices for the needs of the development of the intelligent EMS of the new generation, while ensuring constant monitoring of all devices in the experimental system
