Opis:: Smart Grid is both a concept and a way to mitigate infrastructural deficiencies and counteract the effects of the growing demand for electrical energy. One of the ways ensuring an increase in power grid’s management efficiency is utilization of the latest communication solutions by use of IT technologies. Such solutions ensure reduced energy consumption and evened 24-hour loads, decreased losses and – thanks to automated energy balancing – increased transfer security. Such solutions will directly translate into increased efficiency of the entire power grid. The present article contains an introduction to smart power grids, perspectives for their development in Poland, as well as an extended discussion of related issues concerning security on the organizational level.

Tytuł:: ITC system security in the context of contemporary challenges for electric power industry
Autorzy:: Czechowski, R.
Rosołowski, E.
Powiązania:: https://bibliotekanauki.pl/articles/410573.pdf
Data publikacji:: 2015
Wydawca:: Politechnika Wrocławska. Oficyna Wydawnicza Politechniki Wrocławskiej
Tematy:: smart power grid
digital security
transport protocol
smart metering
remote control
security policy
Opis:: In recent years, electric power systems, in order to improve their efficiency, are increasingly using the latest innovations in the field of information and communication technologies (ICT) starting from wireless communication and fiber optics systems. Both used for industrial automation purposes and complex data analysis. Those systems, year by year, have made use of more and more sophisticated communication algorithms leading to automatic management of energy distribution process as well as undertaking the system resuscitation tasks as a result of failure. The use of ICT communication equipment in electric power systems is certainly a big advantage, but it also entails some safety issues. The traditional understanding of smart grid cyber security involves the general requirements (placed on existing systems) as well as specific solutions for detection and intrusion prevention (for individual parts of the system infrastructure). Implementation of security policy in management process of the power system, with means of modern technical of digital information transmission, will increase efficiency and reliability of those systems.

Tytuł:: Short-Circuit Current Contribution from Large Scale PV Power Plant in the Context of Distribution Power System Protection
Autorzy:: Bejmert, D.
Sidhu, T. S.
Powiązania:: https://bibliotekanauki.pl/articles/410525.pdf
Data publikacji:: 2012
Wydawca:: Politechnika Wrocławska. Oficyna Wydawnicza Politechniki Wrocławskiej
Tematy:: grid-connected PV power plant
transient analysis
fault contribution
overcurrent protection
Opis:: The interconnection of distributed generators (DG) to existing network may give rise to many technical problems. To ensure appropriate power quality and stability of the grid these problems should be recognized and solved. For this purpose, behaviour of such energy sources, under various disturbances, must be studied and known to the distribution grid operators. In this paper fault current contribution from large scale photovoltaic (PV) power plant as well as protection issues concerning such DGs are discussed. The mentioned problems were investigated in PSCAD model of 50 MW grid--connected PV power plant where various operating condition of the network and penetration levels of PV were considered.
